Special conditions
· If the host doesn’t reserve the next disc or track, the Next Disc NO and Next Track
NO(Byte711) should be “0” .
· accepting play command which specifies the same track as current track,It ignores the
command. If the next disc or track of this command is different from the current one ,It renews the next
disc or the next track.
· This command is valid only when the system status is Disc Sense Complete (3).
· When the current track becomes paused during continuous playing, the unit proceeds to a
reserved track by issuing the PLAY command again. Only PLAY and STOP commands are available in
the automatic pause status.
· In the multi-zone mode, a disc used in a zone (specified as a current disc) cannot be specified
as a current disc in the other zone. It can be specified as a next disc in the other zone. However, to start
reproduction of the next disc, it is required that the disc by the current zone has been completed and
returned to the rack.
· When an non-existing track is specified before TOC reading is completed, the maximum track
is reproduced in case the track is outside the maximum track or the minimum track is reproduced in
case the track is before the maximum track.
· When the current and next disc numbers are the same, and only when the next track number
is one track larger than the current track number, the player starts playback of the next track upon
completion of the current track, without entering auto-pause mode.
