Choosing an Optical Disk Type
Two disk types can be used in this drive: 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.
NOTE Do not use write-once disks in a computer system that does not support write-once
disks. Check that your application software supports write-once disks.
