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. The semiconductor laser may be easily damaged by electrostatic charges. When handling the pickup, take care so that
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
pushed ahead a little. When the tray is pushed out, the slide rack is disconnected from the tray pinion, and at the same
time the gear at the rear side of tray is connected with the tray pinion, and the tray is pushed ahead.
When the tray is pushed out fully, the slide rack moves further in the arrow direction through the groove at the rear 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.
This groove is linked with the pawl of
pickup mechanism.

(2) Pickup feed mechanism
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.
When it is moved to the innermost periphery, the position detection switch E is pushed by the rack, so that the position

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.)
2-focus objective lens
The VR terminal is connected to GND.
Actuator assembly
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
the laser diode is reduced if the current of the monitor diode increases. On the contrary, the drive current of the laser diode is increased
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).

8-4-5. 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.

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.)

After measurement is ended in the servo
step test mode,the servo adjustment value
reading-out mode is selected.
After the servo step test, the internal circumference
SW value (ID) display is not defined.
In the servo adjustment value reading-out mode,
the focus offset value is first displayed. Every input
of PLAY key, the displayed data is changed as
shown in the left.
