18. Measurements and Adjustments

Note:

Because this unit uses the optical magnetic recording, the unit outputs over 10 times more laser than a CD player does. In adjustment mode, the laser is always being output. Therefore, be

Page 34

especially careful not to look laser beam directly or to touch the laser beam when adjusting the unit and checking its operation.

18.1. Laser Power Adjustment

Adjust each laser power: read power for reading (play) and write power for writing (record).

18.1.1. Necessary Instruments

- Laser power meter (LE8010)

- Test disc (Pre-mastered disc RFKV0006 or RFKV0014)

- Recordable disc available on sales route (with music recorded)

- Insulated driver for adjustment such as a ceramic driver

18.1.2. Set the Unit to the Adjustment Mode

Perform the (Step 1) and (Step 2) in the item 7.2. Checking for the MD servo P.C.B. in Operation Checks and Component Replacement Procedures.

Caution:

1. About handling the MD unit

- The magnetic head is precision unit and is very fragile. Do not deform it.

- Laser diode in the optical pickup may be destroyed by the static electricity generated in your clothes or body. Be especially careful with the static electricity.

- The optical pickup is structured extremely precisely. Do not subject to the strong impact or shock. Do not touch the lens.

2. About handling the magnetic head When replacing the magnetic head, do not tighten the mounting screw (RHD17022) too firmly. If the screw is tightened too much to deform the resin, the position of the head is moved, and this affects its recording operation. Recommended torque for mounting screw: / 700±100 g cm

Reference:

This is the same force as using a screwdriver with a 15-mm diameter grip, you fasten the screw naturally with your thumb and index finger.

3. About the driver for adjusting laser power Use only insulated driver such as a ceramic driver. With the metal driver, it is not possible to adjust properly because of induction noise. Also, if it short-circuits with the chassis, it may destroy or

Page 35

damage the laser diode. Recommended driver: VESSEL 9000 1.8-30 / (Ceramic driver)

Caution on optical pickup:

- The optical pickup and the magnetic head are structured precisely;

therefore, they are very fragile. Be careful not to touch them with the edge of laser power meter.

- The sensor of the laser power meter is a very fine part. Be careful

not to touch it to the optical pickup lens.

- The focus point of the laser reaches to 180°C. Therefore, avoid

using laser power for a long time because the sensor of the laser power meter may be burned.

- Do not allow the write power to even momentarily reach or exceed

5.5 mW. Doing so will result in damage to the optical pickup.

- Do not set the unit to the laser power adjustment mode with the

MD loaded. Doing so may result in damage to the MD.

18.1.3. Adjustment Procedure

1. Remove the MD unit from the system unit.

2. Short-circuit the IC10-pin 67 (TP77) and GND (TP74) with the lead wire. (This enables the unit to enter the operation mode and to active the operation switches on the front panel.)

3. Set the MD unit in the system unit and turn on the power. The LED of REC and PLAY will light up.

4. Slide the sensor cover of the laser power meter. / Refer to Fig. 18-

Fig. 18-1.

5. Position the sensor of the laser power meter directly above the optical pickup. Refer to Fig. 18-2.

Fig. 18-2.

Page 36

6. Press the CD EDIT button and confirm that the reading of the laser power meter is within the specified range. If it is not within the specified range, adjust by turning VR1. Refer to Fig. 18-3.

Fig. 18-3.

Specified range (read power): 600 W or lower

Caution:

Proceeding on to the subsequent adjustment procedure with the read power exceeding 600 W will result in damage to the optical pickup.

7. Press the CD EDIT button and read the write power. Specified range (write power): 4.8 mW±0.1 mW

8. If it is not within 4.8 mW±0.1 mW, adjust by turning VR1. Refer to

Fig. 18-3.

Caution:

Do not allow the write power to even momentarily reach or exceed

5.5 mW. Doing so will result in damage to the optical pickup.

9. Press the CD EDIT button, the read power will be displayed again. / Confirm that the read power is within 540 W ~ 660 W.

10. Then, again press the CD EDIT button. The laser power recorded in the laser ROM will be displayed. Confirm that it is within 540 W ~ 660 W.

Page 37

11. Press the STOP button and exit the adjustment mode.

12. Turn off the power and remove the lead wire between the IC10pin 67 (TP77) and GND (TP74). This ends the adjustment mode.
