15. Disc distinction threshold value (CD and unrecorded
disc)
Threshold value of the disc distinction. Distinguish it from
CD if bigger than this value, and distinguish it from an
unrecorded disc if small.
16. Current jitter value
Indicate the value that was read in from the MY-CHIP in
DVD, and indicate the value that was read in from the servo
DSP in CD.
17. Focus balance setting value of L0
18. Focus balance setting value of L1
19. Current mechanism controller inside mode
(it does not support in this unit)
It can indicate to a maximum 10 modes. Indicate only a nest
share of the mode.
20. Processing step of 11 inside modes
(it does not support in this unit)
It can grasp the current mode, the mode reaching it and
transition of step by watching 19 and 20.
21. Spindle control state of MY-CHIP
(it does not support in this unit)
OFF
: Motor off condition
A/B : Accelerator and brakes
FG : FG servo
RVP : Rough speed phase servo
ORVP : Rough speed phase servo of offset addition
22. Rotation number of spindle motor
Do not FG read in ? indication (during spindle stop).
23. Tracking error generation system
(it does not support in this unit)
1: 1 beam (DPD)
3: 3 beams
24. TZC count value
(it does not support in this unit)
The value that counted the number of TZC for one rotation in
the tracking open state.
When this value is more than 512 with CD, set it in 1 beam
because the eccentric is large.
DVD does not measure it because it is 1 beam fixed
(indication is 0000).
25. It indicates the frequency that entered the focus backup
Hexadecimal number indication. Counter does not reset till
turns the power off after turning it on. Due to a 1 byte
counter, next of FF becomes 00.
26. It indicates focus backup limit frequency with the
hexadecimal number
Initial value is 14H, it does decrement whenever enter the
focus backup and it gives up backup if it became 0. Then the
error is generated. After reverted from the backup, When not
enter the backup and pass fixed time (1500ms), return to
initial value again.
27. It indicates the frequency that entered the internal
circumference plunging into backup of the sled
Hexadecimal number indication. Counter does not reset till
turns the power off after turning it on. Due to a 1 byte
counter, next of FF becomes 00.
28. It indicates the frequency that entered the tracking
overrun backup
Hexadecimal number indication. Counter does not reset till
turns the power off after turning it on. Due to a 1 byte
counter, next of FF becomes 00.
29. It indicates the limit frequency of tracking overrun
backup with a hexadecimal number
Initial value is 03H, it does decrement whenever enter the
tracking overrun backup and it gives up backup if it became
0.
30. It indicates the frequency that entered sled overrun
backup
Hexadecimal number indication. Counter does not reset till
turns the power off after turning it on. Due to a 1 byte
counter, next of FF becomes 00.
31. It indicates the limit frequency of sled overrun backup
with a hexadecimal number
Initial value is 03H, it does decrement whenever enter the
sled overrun backup and it gives up backup if it became 0.
32. It indicates the frequency that entered the tracking close
NG backup
Hexadecimal number indication. Counter does not reset till
turns the power off after turning it on. Next of FF is be a 1
byte counter in 00.
The hexadecimal number indication which indicates the
frequency that reads
33. ID/subQ, and entered NG backup
Hexadecimal number indication. A counter does not reset it
till cuts it off after turning it on. Due to a 1 byte counter, next
of FF becomes 00.
34. An address to indicate in 35
Set it by using RS232.I
(an address) Set it with DA.
35. Contents of an address indicated in 34.
