Error correction *5 Correctable up to 8-byte/interleave
Bit error rate: 10 -12 or less
*1 The number of user tracks indicates the maximum user zone which includes
the spare area and slipping area.
*2 Mathematical average of 1,000 times of seek and does not include command
overhead nor track address recognition time. Furthermore, it may depend
on the quality of media and drive installation environment.
*3 Loading time is the time from when the optical disk cartridge is inserted to
when the optical disk drive is ready.
*4 Unloading time is the time from when the eject button is pressed or the eject
command is issued to when the optical disk cartridge is ejected.
*5 The bit error rate must be 10 -12 or less when a disk whose raw error rate is
10 -4 or less is used.
