Glossary
Access times. The average
amount of time to access an
item of data.
Amorphous. Lacking shape, or
in mineral terms, not
crystalline. Amorphous could
be taken to mean a liquid or
gel like state. In terms of CD-
RW the important aspect is
that the material will remain
stable in this state (not change
out of this state unless acted
upon by an outside force of
great heat) AND that the
amorphous state has a
different reflective quality than
in a crystalline state.
Analog. (as opposed to digital)
where digital is defined
discrete items which can be
reduced to zero and one bits.
Analog is continuous, so on
any graphic representation of
analog data there are an
infinite number of points
between any two points.
Digital approximates analog
by adding data points.
Archive. To save files or
records, usually in a safe place,
for later retrieval.
ATAPI. AT Compatible
Attachment Packet Interface.
An enhancement to EIDE
which allows CD-ROM type
devices use the EIDE interface.

Buffer. RAM Cache that is
faster than the data is being
delivered. Buffers are used so
data may be stored and
delivered to the receiving item
as it is needed.
Buffer Underrun. When a
function (such as writing to
CD-R media requires a
constant stream of data),
attempts to pull data faster
from the buffer than data can
be input from a source drive,
and the data buffer becomes
empty.
Burn a CD. Recording a CD-R.
Because a laser is used to write
a CD it is also known as
burning a CD.
Burst transfer. The fastest a
device can transfer, usually
from its buffer.
CAV. Constant Angular
Velocity. Constant Angular
Velocity means the drive or
media spins at a constant rate,
rather than spinning faster or
slower as was common with
older CD-ROM devices which
used CLV (Constant Linear
Velocity). CLV drives cause
performance degradation at
higher speed because there is a
lag time, or latency period,
before the drive reaches a
standard readable speed for
each track. See CLV.
CD-R drive. A drive that can
