Acronym for Partial-Constant Angular Velocity,
also called partial CAV, P-CAV a method of writing data to
CD-R and CD-RW
media. Using artial-Constant Angular Velocity means
that when data is recorded to the inner part of the CD,
the disc rotates at a constant speed but the data is
delivered at a a variable speed. On the outer
portion of the CD, the data is recorded at a constant rate but the speed at
which the disc turns varies.
Understanding CD-R & CD-RW Recording Speeds The amount of time taken to write a disc depends upon the speed of the recorder, the writing method used by the recorder and the amount of information required to be written. Recording speed is measured the same as the reading speed of ordinary CD-ROM drives and players.
