: Cleaning
(For cleaning, use a lint-free cloth danpened with pure isopropyl alcohol.)
Use the following table as a guide to maintain the mechanical parts in good operating condition.
CARES WHEN USING THE PICKUP
1. The laser light having wavelength 650 nm is emitted from the objective lens. BE CAREFUL SO THAT THE LASER
LIGHT DOES NOT ENTER DIRECTLY INTO YOUR EYE.
2.Thesemiconductorlasermaybeeasilydamagedbyelectrostaticcharges.Whenhandlingthepickup,takecaresothat
the electrostatic charge is not generated.
3. The semiconductor laser may be easily damaged by overcurrent. Use the power supply unit which does not give any
spike current when the power is turned on and off.
4. Carefully remove the dust and dirt from the objective lens with the lens blower.
When handling the objective lens, take due care so that it is not contaminated with fingerprint, etc. If the objective lens
is contaminated, impregnate the cleaning paper with a small quantity of solvent (isopropyl alcohol), and gently wipe to
clean.
5. The ozone layer depleting components (ODC) are not used in the production process for the product.

7. EXPLANATION OF MECHANISM
(1)Tray loading mechanism
When the tray loading motor rotates counterclockwise, motion is transmitted to the slide rack D through the intermediate
gear 1 A , intermediate gear 2 B and tray pinion C , resulting in insignificant motion in the arrow direction.
The slide rack is linked with the operating chassis. It lowers the pickup mechanism.
The protrusion of slide rack E is linked with the tray through the groove at the rear side of tray, so that the tray is
pushedaheadalittle.When thetrayispushedout,thesliderack isdisconnectedfromthetraypinion,and at thesame
time the gear at the rear side of tray is connected with the tray pinion, and the tray is pushed ahead.
Whenthetrayispushedoutfully,thesliderackmovesfurtherinthearrowdirectionthroughthegrooveattherear side
of tray. The tray position detection switch F is turned on, and the tray loading motor stops.
When the tray closes the operation is as follows. If the tray OPEN/CLOSE button or tray is pressed and the detection
switch is turned off, the tray loading motor rotates clockwise, so that the tray is retracted. When the detection switch
is turned on again, the tray loading motor stops.

When the sled motor A rotates, the rack C moves through the sled pinion B so that the pickup D is moved to the
internal or external periphery.

(3)Disc rotation mechanism
The spindle motor is used to rotate.

8-4. SIGNALS OF PICKUP
8-4-1. Tracking drive signal (TR+, TR-)
The signal drives the tracking servo mechanism which projects the beam on the track by moving the objective lens (OL) to the outer
or inner circumference (at a right angle against the track) of the disk.

8-4-2. Focus drive signal (FO+, FO-)
The signal drives the focus servo mechanism which aligns the focus on the pit of the disk
by elevating OL (vertically against the disk surface.)
The VR terminal is connected to GND.
8-4-3. Monitor Diode (PD)
Since the laser diode largely varies output of the laser light even if the flowing current is slightly varied, the projection
light is detected with the monitor diode to control the laser light to be equally output.
Since the current varies on the monitor diode according to the intensity of the received light of the laser diode, the drive current of
thelaserdiodeisreducedifthecurrentofthemonitordiodeincreases.Onthecontrary,thedrivecurrentofthelaserdiodeisincreased
if the current of the monitor diode decreases.
As the projection light of the laser diode becomes stronger, the current of the monitor diode increases to increase the current which
flows into the monitor diode output (PD). This is input to the pin 44 of IC303 and is compared with the reference voltage to control
the drive current of the laser diode.
The circuit is called ALPC (Automatic Laser Power Control).
8-4-4. Laser diode drive current control (LD)
Power supply to drive the laser diode
8-4-5. High-frequency convolution module power supply (VOSC)
The high-frequency convolution imposes the high-frequency signal on the DC current to impose the high frequency on the drive
current of the laser. Thus, the interference of outgoing light and reflected light is prevented.
8-4-6. HF Signal (VA, VB, VC, VD)
Signals recorded in the disk When the quantity of laser light increases, the current shown in
figure increases and the PD terminal voltage rises.
IC303 is used to control. The LD terminal voltage lowers, and
the quantity of light reduces. (IC303 is actuated by voltage
input.)
