constant linear velocity

(storage)
(CLV) A disk driving scheme in which the linear velocity of the disk is kept constant. This requires that the angular velocity of the disk be larger when the reading or writing tracks closer to the axis. The advantage of this technique is that the read/write speed is constant. However, as mechanical stability puts an upper limit on the angular velocity (and not the linear velocity) using the same linear velocity throughout, i.e., using less then the maximal angular velocity at outer tracks means that the full potential of the drive is not used.

The CRW3200 is also the first 24X drive to use partial Constant Angular Velocity, which reduces write time over competitive drives based on the traditional Zoned Constant Linear Velocity.
By replacing the older Constant Linear Velocity (CLV) technology with Constant Angular Velocity (CAV) technology, the LaCie CD-RW drive also provides 32x playback and fast, 150 ms access.
Like other members of the CRW2200 LightSpeed2(TM) family, CRW2200SZ also takes advantage of the Partial Constant Angular Velocity (P-CAV) technology, a combination of CAV and standard Constant Linear Velocity (CLV) technology, for optimum performance.
0 GB standard by retaining all critical features: in-groove recording, providing both Constant Linear Velocity (CLV) and high-performance Constant Angular Velocity (CAV) recording modes; utilization of a bare disc that does not require a caddy or cartridge; and use of the industry-standard UDF file system.
To achieve the industry's fastest CD-R write speed, Yamaha developed the CRW2100 Series to take advantage of the partial Constant Angular Velocity (CAV) technology, a combination of CAV and standard Constant Linear Velocity (CLV), for optimum performance.
