Physical devices
The following types of physical mass storage devices are supported.
hard disk devices-
Most system software and user files are stored on hard disk.
Hard disks are high-speed, high-capacity storage devices,
and are available in a variety of types (IDE, ESDI, MFM, SCSI) and sizes.
You can usually add new hard disks to satisfy growing storage needs on
your system Most hard drives are fixed, but some are removable.
tape devices-
Because tapes have a high storage capacity
and are portable, they provide an efficient way of
storing and transferring data.
Tape drives are used primarily for
filesystem backups and restoring filesystems or individual files.
Your computer may be equipped with cartridge, 9-track,
digital audio tape (DAT), 8-millimeter, or another type of tape drive.
The
tapecntl(1)
command provides an interface to various media and
drive control operations.
CD-ROM devices-
CD-ROM devices are optical-based, read-only media
used for permanently storing information.
They are useful for accessing large volumes of information.
Medium Changer devices-
Medium changer devices are robotic mechanisms that automate
the movement of storage media (tapes, CD-ROMs, optical) between
storage locations and physical read/write drives. The
mccntl(1M)
command provides an interface to control medium changer devices.
