The number of user tracks indicates the maximum user zone which includes
the spare area and slipping area.
Mathematical average of 1,000 times of random seek, which does not
include command overhead or track address recognition time.
Furthermore, it may depend on the quality of the media and the drive
installation environment.
Loading time is the time that elapses from the time an optical disk cartridge
is inserted, to the time the optical disk drive is ready for processing of an
access command.
Unloading time is the time that elapses from the time the eject button is
pressed or the eject command is issued, to the time an optical disk cartridge
is ejected.
The maximum SCSI data transfer rate may be limited by the initiator
response time, SCSI bus transfer characteristics, or transfer distance.
The bit error rate must be 10
