Code Description Error remedy method Refer to section
02-1A0 Optical block assembly
Ch-1B is recording data with
the maximum laser output.
(On side 0) 1. Eject a cartridge.
2. Check laser parameter 1 of hours meter.
When laser parameter 1 of hours meter has:
• not reached the end of replacement cy-
cle:
There is something wrong with the op-
tical or electrical system in optical
block assembly (OP-1).
• reached the end of replacement cycle:
It is likely laser in optical block as-
sembly (OP-1) reached to the end of its
life cycle.
3. Replace optical block assembly (OP-1).

02-1A5 Optical block assembly
Ch-1B detected a laser out-
put error. (On side 0) 1. Eject a cartridge.
2. Check laser parameter 1 of hours meter.
When laser parameter 1 of hours meter has:
• not reached the end of replacement cy-
cle:
There is something wrong with the op-
tical or electrical system in optical
block assembly (OP-1).
• reached the end of replacement cycle:
It is likely laser in optical block as-
sembly (OP-1) reached to the end of its
life cycle.
3. Replace optical block assembly (OP-1).

02-1A7 Laser drive overcurrent was
detected in optical block as-
sembly Ch-1B. (On side 0) 1. Eject a cartridge.
2. Check laser parameter 1 of hours meter.
When laser parameter 1 of hours meter has:
• not reached the end of replacement cy-
cle:
There is something wrong with the op-
tical or electrical system in optical
block assembly (OP-1).
• reached the end of replacement cycle:
It is likely laser in optical block as-
sembly (OP-1) reached to the end of its
life cycle.
3. Replace optical block assembly (OP-1).

02-820 Data was played with the
maximum laser output in op-
tical block assembly Ch-0A.
(On side 0) 1. Eject a cartridge.
2. Check laser parameter 0 of hours meter.
When laser parameter 0 of hours meter has:
• not reached the end of replacement cy-
cle:
There is something wrong with the op-
tical or electrical system in optical
block assembly (OP-0).
• reached the end of replacement cycle:
It is likely laser in optical block as-
sembly (OP-0) reached to the end of its
life cycle.
3. Replace optical block assembly (OP-0).
