OptiPac 6611MD User's Manual 1

Congratulations on purchasing what we think is the finest removable
cartridge system on the market. Bering OptiPac drives are built for years
of reliable service. We're sure you'll agree as you begin to work with
your drive.
Features The Bering OptiPac 6611MD subsystem is a 1.3GB Magneto-Optical
removable cartridge disk drive with a 1.3GB fixed disk compatible with
Hewlett-Packard 1000E, M, or F computers running RTE-IVB and RTE-
VI. In this manual we refer to the Bering OptiPac disk drive as OptiPac
and all HP systems as computer, unless otherwise indicated.
Note: The Bering OptiPac 6611MD magneto-optical cartridge drive supports
1.3GB and 640MB cartridges. These cartridges are available through
Bering Technology’s sales department.
Serving a wide range of storage needs, the OptiPac comes in the
following configuration with HP7906M emulation. This provides a plug
and play solution to the aging inventory of HP7906M, 7920, and 7925
disk drives.
•6611MD – a 1.3GB Magneto-Optical cartridge drive with a 1.3GB fixed
disk
The OptiPac 6611MD subsystem uses a 3.5 -inch removable cartridge
which can store 1.3GB. This means:
•Each cartridge contains multiple rings, so physical removal is not
required to change to another ring. Each ring emulates a 10MB HP
7906M cartridge.
•Your storage capacity is limited only by the number of cartridges you
use.
•Your data is portable and secure. Just remove the cartridge from the
drive and take it with you, or store it in a safe place.
•Your data cartridge is protected in a durable case.
•Your OptiPac can be used to back up the data on fixed disks.
The OptiPac provides fast, reliable storage that's always on hand. No
software or hardware modifications are required. The OptiPac supports
the AMIGO HP disk command sets.
The fixed disk and each cartridge is split into multiple 10.1 MB Rings,
which emulate a 10MB cartridge in the HP 7906M. The fixed disk has
100 (H0–H99) rings and each removable 1.3GB cartridge has 100 rings
(0–99), depending on the cartridge capacity and sector size. Selecting a
INTRODUCTION

ring from the front panel of the OptiPac is equivalent to changing the
cartridge in the 7906M. The first ring on the fixed disk (H00) emulates
the fixed disk in the 7906M, and is not accessible from the front panel
controls.
The rings on the fixed disk will all have an ID on the LCD display
beginning with “H.” Each ring on the removable cartridge is just a
number. So ring 23 on the hard drive will be displayed as “H23,” while
ring 23 on the cartridge will be displayed as “23.”
▲DANGER: Use of the OptiPac other than as prescribed in this manual may result in
exposure to hazardous invisible laser radiation if the case is open during
operation. Avoid direct exposure to laser radiation. Do not operate the
OptiPac while the cover is removed.
Compatibility The OptiPac subsystems read, write, and format ISO 128MB, 230MB,
640MB cartridges, and the GIGAMO 1.3GB MO cartridge. The number of
rings is smaller on any cartridge smaller than 1.3GB. Use the “Show
Cartridge Information” function using the front panel control buttons
to determine the number of rings on an inserted cartridge.
Regenerating the
Operating System
Your HP operating system does not require regeneration if the 2000MX
MAC controller board replaces an HP 13037 MAC controller in the same
slot where the HP MAC controller was removed from.
If the 2000MX is inserted into any other slot, the operating system will
have to be regenerated.
Magneto-
Optical
Technology
All of the Bering OptiPac disk drives are based on magnetic and optical
technology. Like hard disks, a Magneto-Optical drive writes data to the
cartridge using a strong magnet that changes the magnetic fields at
specific locations from 1's to 0's and vice versa. But because of the
polycarbonate surface of the cartridge, the magnet is not powerful
enough to change the polarity of a bit by itself. This is where the optical
part of the write process comes in. In order for the magnet to change
the polarity of a bit, the area must be heated to a high temperature by
a focused, fine-point laser.
Because of the polycarbonate substrate on the cartridge, data stored on
Magneto-optical cartridges is highly secure for a long period of time.
The estimated storage life of data stored on this media is greater than
twenty years. Also the magnetic head does not “float” next to the surface
such as fixed disks. This means it is virtually impossible for the head
to crash.

Conventions in this Manual
OptiPac 6611MD User's Manual 3
Conventions in
this Manual
We'll use the following conventions to make the information in this
manual more clear and predictable:
•Keys on the keyboard are indicated by capital letters enclosed in square
brackets, e.g., [ENTER], regardless of whether the characters on your
keys are actually capitalized. On the other hand, buttons on the OptiPac
are indicated by underlined capital letters alone followed by the word
button, e.g., ENTER button.
•A font like this indicates text you should see on the LCD. The bold font
will otherwise follow the conventions herein.
•Italics in any type face, like this, have a limited number of possible
meanings:
Words as words, letters as letters, or numerals as numerals, e.g., “the
word enter can be confused with the key on your keyboard, therefore
we will use type in its place.”
Titles of books, booklets, or disks, e.g., Bering OptiPac 6611MD User's
Manual
Symbolic of variable words, characters, or numerals. That is, something
must be in the variable's place, but the exact contents vary with different
situations and cannot be specified without knowing a particular
situation. Variable is not synonymous with optional. Frequently the
letter(s) n(for numerals), or x(for words or characters) are used to hold
the place of the variable, e.g., “the program will respond that there are
nwidgets.”

Ejecting a Cartridge It is important to remove the cartridge before you turn off the OptiPac.
If you leave the cartridge in the drive, the shutter remains open and the
recording media itself is vulnerable to dust. If the OptiPac is turned off
prior to cartridge removal, the automatic disk spin-down operation
does not occur and the cartridge disk will spin freely for up to 45
seconds. Attempting to remove the cartridge during this time may
damage the media.
The OptiPac must be turned on before you can unload a cartridge. If the
Drive button is enabled, which is the default, just press the eject button
on the front of the MO drive and proceed directly to step 3. If the drive
button is disabled perform the following steps to eject a cartridge.
1. With the time function displayed on the LCD, push the SELECT button
on the front panel.
The Unload cartridge function(s) will be displayed. For the 8602 dual-
drive system two options will be available:
Unload cartridge
2. Push the ENTER button to execute the command.
The cartridge will spin down and eject from the drive.
Note: NEVER eject a cartridge while the file system is mounted on your
operating system.
3. Remove the cartridge carefully and place it in the protective plastic
storage case immediately.
Remember to label and date the cartridge for future reference. Do not
mark on labels with a graphite pencil. The graphite dust may
contaminate the disk surface. Refer to Chapter 5, “Caring for The Disk
Drive & Cartridge,” for further information on cartridge care.
Ejecting a Cartridge
Without Power
While the OptiPac is not powered on, you can manually eject a cartridge.
