Using Optical Disks
Choosing an optical disk
Optical disks are available in two capacities, 650 Mbytes and 1.3 Gbytes.
The RWZ52 can read from and write to both 650-Mbyte disks and 1.3-
Gbyte disks. However, RWZ52 users should choose 1.3 Gbyte optical
disks to receive maximum storage capacity.
Two types of optical disks are available: rewritable disks and write-once
disks. To choose which type of disk 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 your disk choice.
•
Both rewritable and write-once disks come in two sector sizes:1024
bytes/sector and 512 bytes/sector. The sector size you choose depends
upon what type of operating system you are running on your
computer, and which software package you have chosen. Digital
operating systems support 512 byte sectors only. Refer to your
computer system documentation or your optical driver software
documentation to see which format is supported on your computer.
The information is probably listed under optical disk sector size or
optical disk format.
NOTE:
Do not use write-once disks in a computer system
that does not support write-once disks. Check
your computer system reference manuals to
determine the disk types that are supported.
