@ During TOC reading with an LD, the spindle servo was not locked within 60
seconds from the start of the spindle run.
@ When CAV/CLV determination is not finished within 60 seconds from
spindle servo lock.
@ The codes could not be read for 10 — 15 seconds consecutively for an LD or
7 — 10 seconds for a CD/CDV and the spindle servo was not locked.
@The speed exceeded 2100 rpm during LD start up.

@ "In the "no disc" state, a setup command was received from the mode
controller.
@ When LD is out of focus when slider is moved to starting position during set

@ During start-up, the maximum slider servo duty continued for 3 loops or
more.
