SECTION 1
PRECAUTIONS
1.1 SAFTY PRECAUTIONS
Prior to shipment from the factory, JVC products are strictly
inspected to conform with the recognized product safety and
electrical codes of the countries in which they are to be
sold.However,in order to maintain such compliance, it is equally
important to implement the following precautions when a set is
being serviced.
1.1.1 Precautions during Servicing
(1) Locations requiring special caution are denoted by labels
and inscriptions on the cabinet, chassis and certain parts of
the product.When performing service, be sure to read and
comply with these and other cautionary notices appearing
in the operation and service manuals.
(2) Parts identified by the symbol and shaded ( ) parts
are critical for safety.
Replace only with specified part numbers.
NOTE :
Parts in this category also include those specified to
comply with X-ray emission standards for products
using cathode ray tubes and those specified for
compliance with various regulations regarding
spurious radiation emission.
(3) Fuse replacement caution notice.
Caution for continued protection against fire hazard.
Replace only with same type and rated fuse(s) as
specified.
(4) Use specified internal wiring. Note especially:
• Wires covered with PVC tubing
• Double insulated wires
• High voltage leads
(5) Use specified insulating materials for hazardous live parts.
Note especially:
• Insulation Tape
• PVC tubing
•Spacers
• Insulation sheets for transistors
•Barrier
(6) When replacing AC primary side components (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of
wires securely about the terminals before soldering.
Fig.1-1-1
(7) Observe that wires do not contact heat producing parts
(heatsinks, oxide metal film resistors, fusible resistors, etc.)
(8) Check that replaced wires do not contact sharp edged or
pointed parts.
(9) When a power cord has been replaced, check that 10-15
kg of force in any direction will not loosen it.
Fig.1-1-2
(10) Also check areas surrounding repaired locations.
(11) Products using cathode ray tubes (CRTs)In regard to such
products, the cathode ray tubes themselves, the high
voltage circuits, and related circuits are specified for
compliance with recognized codes pertaining to X-ray
emission. Consequently, when servicing these products,
replace the cathode ray tubes and other parts with only the
specified parts. Under no circumstances attempt to modify
these circuits.Unauthorized modification can increase the
high voltage value and cause X-ray emission from the
cathode ray tube.
(12) Crimp type wire connectorIn such cases as when replacing
the power transformer in sets where the connections
between the power cord and power trans former primary
lead wires are performed using crimp type connectors, if
replacing the connectors is unavoidable, in order to prevent
safety hazards, perform carefully and precisely according
to the following steps.
•Connector part number :E03830-001
•Required tool : Connector crimping tool of the proper
type which will not damage insulated parts.
•Replacement procedure
a) Remove the old connector by cutting the wires at a
point close to the connector.Important : Do not
reuse a connector (discard it).
Fig.1-1-3
b) Strip about 15 mm of the insulation from the ends
of the wires. If the wires are stranded, twist the
strands to avoid frayed conductors.
Fig.1-1-4
c) Align the lengths of the wires to be connected.
Insert the wires fully into the connector.
Fig.1-1-5
d) As shown in Fig.1-1-6, use the crimping tool to crimp
the metal sleeve at the center position. Be sure to
crimp fully to the complete closure of the tool.

1.1.2 Safety Check after Servicing
Examine the area surrounding the repaired location for damage
or deterioration. Observe that screws, parts and wires have been
returned to original positions, Afterwards, perform the following
tests and confirm the specified values in order to verify
compliance with safety standards.
(1) Insulation resistance test
Confirm the specified insulation resistance or greater
between power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks,
earphone jacks, etc.).See table 1 below.
(2) Dielectric strength test
Confirm specified dielectric strength or greater between
power cord plug prongs and exposed accessible parts of
the set (RF terminals, antenna terminals, video and audio
input and output terminals, microphone jacks, earphone
jacks, etc.). See Fig.1-1-11 below.
(3) Clearance distance
When replacing primary circuit components, confirm
specified clearance distance (d), (d') between soldered
terminals, and between terminals and surrounding metallic
parts. See Fig.1-1-11 below.
Fig.1-1-8
(4) Leakage current test
Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed
accessible parts (RF terminals, antenna terminals, video
and audio input and output terminals, microphone jacks,
earphone jacks, etc.).
Measuring Method : (Power ON)Insert load Z between
earth ground/power cord plug prongs and externally
exposed accessible parts. Use an AC voltmeter to
measure across both terminals of load Z. See Fig.1-1-9
and following Fig.1-1-12.
Fig.1-1-9
(5) Grounding (Class 1 model only)
Confirm specified or lower grounding impedance between
earth pin in AC inlet and externally exposed accessible
parts (Video in, Video out, Audio in, Audio out or Fixing
screw etc.).Measuring Method:
Connect milli ohm meter between earth pin in AC inlet and
exposed accessible parts. See Fig.1-1-10 and grounding
specifications.

SPECIFIC SERVICE INSTRUCTIONS
2.1 Handling Microdrives
Microdrives are used in GZ-MC100 and GZ-MC200. Although the appearance is different, a Microdrive is exactly the same as a hard
disc that is used in a PC. Therefore, unlike handling conventional tapes, caution must be paid in handling Microdrives.
The handling of Microdrives is explained in this section.
2.1.1 The structure of Microdrives
The detailed inside structure of Microdrives is not disclosed as it is treated as trade secrets. However, it is essential to have knowledge
of the structure of Microdrives in order to carry out service properly. Some information about Microdrives is given here.
A Microdrive is mainly consisted of the following parts.
• A magnetic recording disk that is coated with magnetic ma-
terial. (Disk)
• A reading/ writing head. (Head)
• A motor that turns the disk.
• A circuit board that is loaded with electrical circuit which con-
trols the motor, the head positioning, and input/ output of the
signal.
1 head type Microdrives use one side of the disk, and 2 head type
Microdrives use both sides of the disk with heads on each side
of the disk.The disk and the head do not contact and there is
certain space kept between them. The head reads the pre
recorded servo information to control the head itself. When the
head is not in access to the disk, it is kept in a shelter to avoid
damaging the disk with shocks from outside.
The difference between a 2GB Microdrive and a 4GB Microdrive
is only whether it has one head or two heads and there is no
difference in performance, as shown in the specification list. A
2.5 inch hard disk that is used in a note PC is shown as a
reference. As a 2.5 inch hard disk is bigger than a Microdrive, it
has more disks and heads resulting in more capacity. On the
contrary, it seems impossible to increase the disks for a
Microdrive because of size restriction. High capacity will be
achieved by improving the areal density and rotation speed of the
future products.
Shock tolerance during non-operation is remarkably high. Micro-
drives are designed to tolerate shock during non-operation as
they are removed or carried out more often than other hard disks.
However, Microdrives are vulnerable to falls and shocks just like
other precision instruments.
Microdrives are made in conformity with the standard of Com-
pactFlash Type II. The thickness of the drive is less than 5.5mm,
thus failures can occur by folding or twisting the disks. The stan-
dard for torsional stress is 6kg approx. and for flexing stress is
4kg approx. Be sure to carry Microdrives in protection cases on
the service sites, and strongly recommend the customers to do
so, too.

2.1.2 Precautions on handling Microdrives
Main causes of failures in hard disks including Microdrives are
listed as follows.
(1) Failures caused by shocks
(2) Failures caused by static electricity
(3) Failures caused by power cut during the operation
2.1.2.1 Failures caused by shock
One of the causes of the Microdrive failures is a crash between
the disk and the head caused by falls or shocks. The results of
the crash are listed as follows.
• The scratch on the surface of the disk (crash scar) disables
reading/ writing of the damaged part.
• The magnetic material that came off by the crash (disk frag-
ment) causes head reading failure.
• The head distortion deteriorates the read/ write attribute.
• The change in the space between the head and the disk dis-
ables the normal read/ write.
Stronger shocks result in the motor axis distortion, causing axial
runout and deterioration in performance such as disabling the
trace of normally recorded signal.
Pay extra caution not to drop or give shocks to the Microdrive
while servicing, and make sure to store the Microdrive in a pro-
vided plastic case.
NOTE:
The shock of 200G(G:Gravity), a maximum impact value in
operation, is equivalent of the impact of dropping from 20-
30cm above the hard floor. The shock of 2000G, a maximum
impact value in non-operation, is equivalent of the impact of
dropping from 75 - 100cm above the hard floor.
2.1.2.2 Failures caused by static electricity
Microdrives are designed to tolerate static electricity up to 15kV
approx. However, head destruction or boot failure will occur as a
result of high static electricity given to the magnetic head of a Mi-
crodrive that is very vulnerable to static electricity.
As same as handling other electronic parts, make sure not to
take charge of static electricity before touching a Microdrive for
checking or repairing.
In addition, make sure to store the Microdrive in a provided plas-
tic case when it is not in use.
The voltage of 15kV has enough power to break Microdrives de-
stroying heads etc. Errors in Microdrives may occur with lower
voltage. Asking the customers about the recording condition:
whether it was inside the car in winter, right after getting off the
car or in the carpeted area of a hotel etc., is recommended to in-
vestigate failures with poor reproducibility.
2.1.2.3 Failures caused by power cut during the operation
When the power is cut off while writing the data on the Micro-
drive, writing failure occurs in the writing sector (512 byte). As a
result, an error will occur while reading the data.
The effects on the system, given by the bad writing sector, de-
pend on the types of the written files on the sector.
If it is user data, the recorded movie may not be replayed.
To prevent failure in writing, do not insert/ remove the Microdrive
or cut off the power unless otherwise indicated or needed.
"Read Sequential Error" may be detected if Full Check of the Mi-
crodrive is performed with the DDD.
NOTE:
"Read Sequential error" may be detected as a result of defec-
tive Microdrive disables the reading. Abnormal reading may
also occur when the user removes the power plug or the bat-
tery while the Microdrive is in operation; the writing is not com-
pleted and the reading cannot be performed normally.
In the latter case, the failure will be corrected by running the
Full Check after the DDD Clean Disk has been performed.
Running the Clean Disk is recommended when the recorded
movies cannot be read or the Read Sequential Error occurs.
If an error is detected even after running the Full Check, other
causes of the failures are considered.

2.1.3 Microdrive backup
Unlike the information on tapes, customers' information on
Microdrives can become unreadable in an instant. Backing up
users' record is strongly recommended to avoid any accident.
The above data shows: the elapsed time of copying the recorded
information on a Microdrive to a PC and the elapsed time of
formatting the Microdrive with the PC.
From the results of the measurement, it is clear that the data
transfer with a commercial USB2.0 Reader/ Writer is about twice
as quick as transfer with a PCMCIA card.
Using USB2.0 Reader/ Writer is recommended when frequent
data backup or data re-writing on the Microdrive is required.
Backup should be performed all the recorded files on the Micro-
drive.
Formatting must be done with the main unit that operates nor-
mally.
If a Microdrive that is more than 2 GB is formatted with the main
unit, it is formatted as FAT (FAT16), and a drive that is more than
2GB is formatted FAT32.
2.1.4 Checking the main unit/ Microdrive good or bad
In order to repair or check MC100 - 200, judging the cause of the
failures, whether it is the main unit or the Microdrive, is essential.
The product failures that are brought into repair/ check fall into
the following categories.
(1) Microdrive failures caused by the users handling such as
fall, shocks, and submergence.
(2) Main unit operation failures caused by the Microdrive fail-
ures.
(3) Microdrive operation failures caused by the main unit fail-
ures.
NOTE:
Unlike DVC tapes, the Microdrives of MC100 - 200 are recog-
nized as parts of the main unit. It is essential that the main unit
and the Microdrive are brought in as a pair for service. Basical-
ly, do not accept the main unit alone for repair or check.
2.1.4.1 Separations of the parts failures
The procedure to identify the causes of the failures whether it is
in the main unit or in the Microdrive is explained in this section.
2.1.4.2 Microdrive failures caused by user handling
As previously explained, Microdrive failures may possibly be
caused by falls or shocks. Further more, dropping Microdrives in
the water causes crucial failures to Microdrives.
Supplied Microdrives (not all the commercial Microdrives) have
the same type of Water Exposure Seal that are used in cellular
phones.
Before checking the failures, check whether there is a Water Ex-
posure Seal display appeared.
In addition, check whether there are any significant scratches,
bends, or dents that shows the sign of falls or shocks.
Other check items are as follows.
(1) Check whether there are any letters written with a pencil or
a pen on the label of the Microdrive. The pen pressure
gives distortion on the Microdrive, resulting in an operation
failure. It is noted in the Instruction Book.
(2) Check whether there are any stickers affixed on the Micro-
drive. The space between the Microdrive and the housing
is very little. Affixing unnecessary stickers may lead load-
ing the Microdrive in a wrong position, resulting in contact
failure or remove disk failure. There is a hole on the reverse
side of the Microdrive for ventilation through special filter.
Sealing the holes gives effect on the operation.
(3) Check whether the Microdrive label is peeled or turned. If
there are peel or turn in the label, the loading failure may
occur. Peels or turns will not occur under normal condi-
tions, thus storage or usage under hot and humid condi-
tion, near organic solvent, or exposure to the direct sunlight
are considered.

2.1.4.3 Main unit operation failures caused by the main unit/
Microdrive failures.
2.1.4.2 There is a possibility of a Microdrive being damaged even
though there is no notable failure in appearance.
Main unit failures also result in abnormal operation in a Micro-
drive.
Identifying the causes of the failures in the main unit is explained
in this section.
In the diagram, MD stands for a Microdrive, CG for a compact
flash card, and SD for a SD card.
2.1.4.4 Operation failures caused by main unit failures
2.1.4.3 Judging from the separation of the main unit and MD, the
operation failure is more likely to be caused by the main unit fail-
ure. However, the main unit failure has not been determined yet,
as there is a possibility of the user MD failure causing the main
unit damage. The following procedure shows how to determine
the main unit failure.
2.1.4.5 Disabled read/ write with other devices
When read/ write cannot be done with the main unit, the main
unit failure is considered in most cases. Recognition failure
caused by the main unit writing bad data can be considered.
The causes of read/ write failures are as listed below.
(1) Damaged mechanism parts or electric parts inside the MD.
(Hardware failure)
(2) Damaged information in the MD. (Software failure)
In the case (1), it seems very difficult to recover, but there is a
possibility of recovery in the case (2) by using commercial software.
The following procedure shows how to figure out whether the
damage is in the hardware or in the software, and whether it is
recoverable or not.
2.1.4.5.1 Microdrive hardware failure
Although no failure was found in the MD appearance at the time
of the separation of 2.1.4.1, actually there is considerable dam-
age disabling the operation. In this case, "Shipping Damage"
(damage caused by the transportation) is displayed as a result of
DDD diagnosis. Surely, a possibility of the products damaged on
route from the production plants to the shops and then to the con-
sumers cannot be denied.
However, MDs are stored in protection cases or in main units and
the transportation shock that damages only the MDs is unrealis-
tic. A failure cause by the user handling is more likely considered.

The main unit operation failure may be
caused by an unrecognizable MD after
user's editing works such as formatting
and adding/ deleting files or
maintenance works such as
defragmentation and check disk done
with a device other than the main unit.

(No.YF058)1-9
Recovery method
Asking a data recovery company (a data salvage company)
seems the only way.
Even if the MD is not recognized a drive, a transmission may be
possible with the MD (light hardware failure). In this case, system
recovery software such as Norton Utilities in Norton System-
Works 2004 (NOTE1: ) may help drive recognition.
Once the drive recognition is recovered, the record may be re-
covered by the method mentioned in 4.5.2 MD software failure.
However, if it is a hardware failure, banning the use of the MD is
strongly recommended.
2.1.4.5.2 Microdrive software failure
Most of the software failures are caused by the unrecognizable
MD after user's editing works such as formatting and adding/ de-
leting files or maintenance works such as defragmentation and
check disk done with a device other than the main unit.
Many cases under this condition, recovery can be done by using
recovery software, which can recover MPEG2 data, such as Final
Data 2.0 Premium. It enables the drive recognition and the data
reading. Once the data is recovered, follow the below procedure.
NOTE1:
Norton SystemWorks 2004 (Latest version on 2004/ 9/ 29)
It is Symantec's data recovery software.
For system requirements and other details, please check their
web site.http://www.symantec.com/region/jp/products/
NOTE2:
Final Data 2.0 Premium Office (Latest version on 2004/9/29)
It is AOS Technologies' data recovery software.
Although there are some kinds of recovery software as FINAL-
DATA series from this company, this is the cheapest one that
can recover MPEG2.
For system requirements and other details, please check their
web site.http://www.finaldata.ne.jp/
2.1.4.5.3 Reusing Microdrives
If a Microdrive of a user is reused for another user, normal data
deletion may not completely erase the previous user's informa-
tion (images) and the previous user's information may come
back. Unlike hard disks of PCs, most of the recorded contents of
Microdrives are images and audio data, thus there is a little pos-
sibility of recorded personal information in Microdrives. However,
proper handling in reusing Microdrives is required as a business
organization.
There are levels in erasing data in disks.
• Level 1: Zero Write method (once)
• Level 2: Random Write method (once)
• Level 3: Random/ Zero Write method (twice)
• Level 4: US Department of Defense (DoD5220.22-M)
• Level 5: US Department of Defense (DoD5220.22-Expanded)
• Level 6: Guttmann method
At least level 3 data erasure is recommended.
Data erasure software is commercially available from software
companies. It seems convenient to use Final Data 2.0 Premium
as there is a data erasing function in it.
2.1.5 Combinations of media and a main unit
MC100 - 200 can record movies, pictures, and audio on compact
flash cards, SD cards in addition to Microdrives. Recording mov-
ies is partially limited. Characteristics of each medium, available
or limited operation items, and available operation time are ex-
plained in this section.
2.1.5.1 Types of media
Commercially available maximum capacity
MC100 - 200 are basically designed to record movies by using
Microdrives.
MC100 - 200 have 2 types of slots, one for a Microdrive or a
Compact Flash card, and the other for a SD card.
From the menu, movies/ pictures/ audio can be selected for a
medium in either one of the slots.
As movies, pictures, and audio can separately select the slots,
using one slot for all recording mode is possible. However, as
movies require large capacity and high transmission speed, the
available recording mode (image quality) is limited.
(Refer to 5.2.3 Image quality and support media.)
Recording movies in Microdrive setting is recommended.
2.1.5.2 Movies
Movies are recorded SD-VIDEO1.1 standard, (images) MPEG-
2-PS (with RDI),(audio) Dolby Digital AC-3, NTSC 60 frame as-
pect 4:3

2.1.5.2.2 Recording time (approximately minutes)
2.1.5.2.3 Image quality and support media
As shown above, Microdrives of 1GB or less, Compact Flash
cards, and SD cards that are not for high transmission speed
cannot record movies except in the economy mode.
If a recording mode other than economy mode is selected and
the recording is started, " Recording cannot be done with this
Medium speed" is displayed.
Microdrives can be judged by the capacity whether they are for/
or not for the movie recording. However, Compact Flash cards
and SD cards are difficult to judge from the appearances.
A Toshiba SD card and a LEXAR Compact Flash card are com-
pared below.
SD card that is operation checked as a high-speed type has
transmission speed of 10MB/s or more. High-speed products
with less capacity (9MB/s etc.) may operate, but operation can-
not be guaranteed.
Compact flash card that is operation checked as a high-speed
type has transmission speed of 40x or more. High-speed
products with less capacity may operate, but operation cannot be
guaranteed.
2.1.5.3 Pictures
Pictures are recorded as JPEG compression picture Exif2..2,
DCF2.0, PictBridge, DPOF standard conformity. There is no re-
striction of picture recording media or spec, but equivalent trans-
mission speed as for movies is required for rapid shooting.
Picture recording is explained as follows.
2.1.5.3.1 Image size and recording numbers
The value varies slightly according on each medium, Microdrive,
Compact flash card, and SD card. In addition, these values are
theoretical values, and it does not guarantee the recording num-
bers.

In the actual display, 2GB and 4GB are converted to Byte. So
it is displayed under the Microdrive display of 2G or 4G with
MB.
5. Testing details
When FullCheckMicrodrive_jvc.pid is carried out, the six kinds
of testing are performed.
(1) Drive Initialization
The test checks whether the drive can recognize or not.
Errors will be detected if it cannot recognize at all as a re-
sult of fall, shock, or submersion. It is more likely to have
a failure in electrical circuit than a mechanical one (mo-
tor).
Checking items:Submersion mark, scratch on the exteri-
or, dent, and bend.
(2) Check Servo Data (DFT)
The test checks whether the disk is decentered or not.
If the motor shaft is decentered as a result of fall or
shock, the interior head cannot pick up the recorded sig-
nal on the disk.
Checking items:Scratch on the exterior, dent, and bend.
(3) Check for Scratches on Media
When a cluster error occurred, an alternative area is cre-
ated to avoid the use of the damaged cluster. This test
checks the distribution of the alternative area. It does not
detect scratches of the user data area caused by fall or
vibration.
Checking items:None
(4) Check Product Internal Error Logs
This test collects the error information that was recorded
at the time of production.
It carries two tasks, checking the Error Logs and the
numbers of the alternative sectors.
Checking items:None
(5) Check GMR Head Amplitude
This test checks the output of the head. Read and write
errors by electrostatic, by shock that changes the dis-
tance between the head and the disk may cause errors
on writing or reading.
Checking items:scratch on the exterior, dent, and bend
(6) Media Test(s)
This test checks whether the written information can be
correctly read or not by comparing writing data and read-

data area. Read the data and write in other data in that ar-
ea, then read the data again to check if the correct read/
write can be performed. Two tests, CSO Read- Write-
Compare and Read Sequential Test that checks all the
sector including the red\cording area, are performed.
Checking items:scratch on the exterior, dent, and bend.
6. Comment on the results of the test
The comment is displayed by totally judging from the six test
on 5. results, and by speculating the cause of the Microdrive
failure.
If there is no problem at all, a comment "DO NOT RETURN TO
YOUR SUPPLIER" is displayed.
If any failure is found on the Microdrive, a comment "RETURN
THIS DRIVE TO YOUR SUPPLIER" is displayed. In the early
stage, the defected parts are analyzed for modification. Please
follow the instruction from JVC.
7. The time and date of the start and end the testing are dis-
played here.
The time and date of the start and the end of the test, and the
testing time are displayed here.
(e.g.) If it was started at 4:30:09 p.m. on Monday, September
13th, 2004, and finished at 4:45:23, and the testing time is 15
minutes and 14seconds, it will be shown as below.

8. Test results
The test results of the six test on 5. are displayed.
If there is no problem at all, "Drive passed Explorer WITHOUT
a problem." Is displayed.
If any failure is found, "READ SEQUENTIAL TEST ERROR" is
displayed to show where the errors are found. Decide the
countermeasure not by this comment but by the comment
sown on 6.
2.1.6.6.3 CleanDisk.pif
The CleanDisk.pif (CleanDisk) is a file which restores the Micro-
drive to its factory settings. It is use to restore the Microdrive to
its factory settings when it does not operate properly as a result
of a failure in format etc. It can also be used to completely delete
the user information on the Microdrive.
(1) Load the PCMCIA card adapter with the Microdrive to be
clean disked, and insert it into the PC card slot of the PC.
*If there are two PC card slots, use the first slot.
CF readers/ writers using USB or drives that can be di-
rectly connected CF cards to the PC can be recognized
as drives on the PC.
However, they cannot to be recognized as media on DDD.
Therefore, please use the PCMCIA card adapter.
(2) Click My Computer to check if the drive is newly recog-
nized.
Usually when recognized on the PC, a new drive letter is
given.
(3) Double click the copied CleanDisk.pif icon on the desktop to
start DDD.
(4) Take off the check at the next of SCSI.
(5) Press the media recognition button ( shown above) to rec-
ognize the medium.
