are returned together as a 10-digit integer. If this command is used
when playing the disc at normal speed, the block numbers are
renewed even while communication is taking place. As shown in the
example below, continuous block numbers may not be received.
Correct values will not be shown if the player is is not in Random
Access Mode, or when playback is in the lead-in or lead out area of
the disc. If a block number code of the disc cannot be correctly
read, the previous value is retained.
