Causes if with a DVD
An ID could not be read for 1 second or more.
An ID could not be read within 1 second after the
AFB adjustment had been finished.
A command could not be issued to DSP because
Command Busy (XCBUSY) was in force
(XCBUSY = L) for a specified time (about 200
mS).
Command Busy (XCBUSY) was in force for a
specified time (about 200 mS) before and after a
coefficient read command was issued to DSP, or
the address echo-back after command issuance
did not match the setup address.
Command Busy (XCBUSY) was in force for a
specified time (about 1024 mS) before and after
the coefficient write command was issued to
DSP.
Command Busy (XCBUSY) was in force for 200
mS during continuous coefficient writing, or
before and after a continuous write command
was issued to DSP.
In the tracing state during the backup sequence, codes could not be read for 1
second or more. In the backup sequence, tracking ON sequence of the servo DSP
could not be completed even if more than 500 mS after the tracking ON command
was issued.
Tracing impossible after retring the tracking ON for 3 times in the backup sequence.
During tracing, runaway was detected after three iterations of backup operations for
detecting runaway.
During playback, the overcurrent detection port was at L for 300 ms or more
continuously.
While the power was on, the overcurrent detection port was at L for 40 ms or more
continuously.
The tray switch that had been Open mode was forcibly changed to a mode other than
Open by an external force.
Loading, unloading or clamping could not be completed within a specified time (about
5 seconds).
The following error occured eight times.
(1) Focus ON sequence could not be completed even if more than two seconds after
the focus ON command (to the servo DSP) was sent.
(2) Focus IN sequence was finished, actually focus IN was not completed.
