Choosing an Optical Disk Type
Two disk types are available for use in the jukebox: rewritable disks and write-once
disks.
To choose which type of disks to use, consider these points:
• Rewritable optical disks--data can be repeatedly written and erased.
• Write-Once optical disks--data can be written only once, and the data cannot be
altered or erased. If you have a need for data security and audit trails, write-once
disks may be a good disk choice.
• Both rewritable and write-once disks come in three sector sizes: 2,048
bytes/sector, 1,024 bytes/sector, and 512 bytes/sector. The sector size you
choose depends upon what type of operating system you have in your host
computer and which software package you use to manage files stored on the
jukebox.
NOTE Do not use write-once disks in a computer system that does not support write-once
disks. Check that your jukebox application software supports write-once disks.
