(DRW2080)
DRW2080
(DRW2069)
DRW2069
1. The ON/OFF(ON:low level,OFF:high level) status of the
CLAMP signals for detcting the loading state are detected
by the drive CPUs, and the design prevents
laser diode oscillation when the CLAMP signal turns OFF.
In normal operation, if no disc is clamped, the laser diode
oscillation is disabled.
However, the interlock does not always operate in the test
mode. *
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 3A
laser beam.
Additional Laser Caution
* Refer to pages 38.

5. PCB PARTS LIST
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

are as follows:
Baud rate
: 38400 (fixed)
Character length
: 8 bit
Stop bit
: 1 bit
Parity
: none
Flow control
: none
Others
: LSB 1st

6.2.4 Radial Tilt Circuit Adjustment
[Procedure]
(1) DVD
"3TL" (Initialize the tilt)
• Enters code "4TL" in the state that does not clamp a disc.
• Calmp the unrecorded DVD-RW disc and enters code "5TL".
• Calmp the DVD-ROM (Dual) disc and enters code "6TL".
• Calmp the DVD-ROM (Single) disc.
"3DT" (Selects DVD-ROM (Single) mode)
"1XN" (Set the CLV normal speed)
"+100000+PL" (Search for address 100000h)
• Connect the jitter meter to RFEQOUT.
"1TL" (Tilt UP) / "2TL" (Tilt Down). Jitter of T edge looks for the point which becomes the minimum.
"7TL" (Obtain the TILT TARGET)
"RJ" (REJECT)
• Clamp the recorded DVD-ROM (Single) disc.
"3DT" (Selects DVD-ROM (Single) mode)
"1XN" (Set the CLV 1th speed)
"+100000+PL" (Search for address 100000h)
• Connect the jitter meter to RFEQOUT.
"1TL" (Tilt UP) / "2TL" (Tilt Down). Jitter of T edge looks for the point which becomes the minimum.
"7TL" (Obtain the TILT TARGET)
"RJ" (REJECT)
(2) CD
• Clamp the Recorded CD-R disc.
"1DT" (Selects CD-R mode)
