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.
• Rewritable and write-once disks come in sector sizes from 4,096 bytes/sector
down to 512 bytes/sector (see Table A-1 in Appendix A). 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.
