Glossary
continuous composite
A format that describes the physical, optical, and data format characteristics of a
disk that complies with ISO DP 10089-2A.
daisy chain
A method of connecting devices in a serial manner which typically starts from
the host. The last device in the chain must be terminated.
device file
The file associated with an I/O device. Device files are read and written just like
ordinary files, but requests to read or write result in activation of the associated
device.
disk
See optical disk.
front panel
The part of the optical drive that includes a power indicator light, function indi-
cator lights, an eject button, and a place to insert and remove disks.
magneto-optical (MO)
A type of optical technology which uses a laser to read from and write to a mag-
netic layer on an MO disk. To write, a spot on the magnetic layer is heated by a
laser to a point where it can be magnetically altered by the write magnetic head.
To read, the light from the laser is reflected from the spot. The magnetic alter-
ation causes the light to be polarized in one direction (interpreted as a "1") or the
opposite direction (interpreted as a "0").
multifunction drive
An optical disk drive that supports both rewritable and write-once optical disks.
The drive detects the disk type by reading a factory-stamped code on the disk.
