*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 10-12or less when a disk whose raw error rate is 10-4or less is used.
