Disc Type Check
Judge automatically the loaded disc. As
the judged result is displayed at the
bottom of screen, make sure that it is
correct.
If Disc Check Memory menu has not
been executed after EEPROM default
setting, the disc type cannot be judged.
In this case, return to the initial menu
and make a check for three types of
discs (SL, DL, CD).

2. Servo Control
On this screen, the servo on/off control necessary for replay is
executed. Normally, turn on each servo from 1 sequentially and
when CLVA is turned on, the usual trace mode becomes active. In
the trace mode, DVD sector address or CD time code is
displayed.
This is not displayed where the spindle is not locked.
The spindle could run overriding the control if the spindle system
is faulty or RF is not present. In such a case, do not operate

For reference, the drive has been designed so that the gain center
value is 20 and offset value is 80. Other values will be in a range
of 10 to 80. If extreme value such as 00 or FF is set, adjustment
will be faulty. In such a case, check for disc scratch or cable
disconnection, then perform adjustment again.
