Using laser technology, optical disk cartridges access
optical
disk drives to seek, read, write, and delete data on optical disks
through the means of two optical media recording processes:
- Write-Once, Read-Many (WORM) media
- Reads from and writes to 5.25-inch, 12-inch, single-, double-,
quad-, and 8x-density WORM optical disk media.
- Magneto-Optic (MO) rewritable media
- Reads from and writes to 5.25-inch, single-, double-, quad-, and
8x-density, rewritable optical disk media.
Note: - The term "rewritable" is used within this document to depict
this type of optical disk media. Also, continuous composite WORM (CCW)
media is included wherever the terminology double-, quad-, and 8x-density
WORM media is used, unless otherwise stated.
- The 3995-SW3 optical disk drive (in all the C3A, C1x, and
C3x libraries) is not capable of writing to any 3995 single-density
(WORM or rewritable) media. It is capable of reading this type of
media, as well as reading from and writing to 3995 double- or quad-density
WORM, rewritable, or CCW optical disk media type.
- The 3995-SW4 optical disk drive (in all the C3A, C1x, and
C3x libraries) is not capable of writing to any 3995 single-,
or double-density (WORM or rewritable) media. It is capable of reading
this type of media, as well as reading from and writing to any 3995
quad- or 8x-density WORM, rewritable, or CCW optical disk media
type.
