Condition 

 Start position, seek position 

 end position 

 FAD  

 FAD = start of disc (150) 

 FAD = top of disk -1 
 (the number of FAD sectors is 0) 

 FAD> End of disc 

 FAD = End of disc + 1 
 (equal to readout) 

 FAD = disc end 

Relationship between start position and end position Start FAD <150

: End FAD = Start FAD + Number of FAD sectors-1 : End FAD = 150 + number of FAD sectors-1

The contents of the playback range that are retained are the start FAD and end FAD.

Condition	Start position, seek position	end position
TNO = 0 (the default value of the track)	TNO = the first track on the disc	TNO = last disc track
X = 0 (index default value)	X = 1	X = 99 (63H)
TNO	TNO = first disc track X = 1 (same as X = 0)	TNO = first track on the disc X = 99 (same as X = 0)
TNO> final disc track	TNO = final disc track X = 1 (same as X = 0)	TNO = last disc track X = 99 (same as X = 0)
X does not exist	(from the next track)	(Until the end of the track)

TNO: Track number, X: Index number

X = 0 means that only the track is specified. (Track start / end index)
TNO = X = 0 is the default value for the position parameter.
(Start position: start of disk, end position: end of disk, seek position: home position)

 
 Specifying the default value for the seek position: Used as a stop command.
.. (Seek to home position)
 Seek position unchanged: Used as a pause command.
 Play range unchanged specification: Used for pause release (resume CD playback).
