constant angular velocity

(storage)
(CAV) A disk driving scheme in which the angular velocity of the disk is kept constant. This means that the linear velocity of the disk be larger when the reading or writing the outer tracks. The disadvantage of this technique is that the read/write speed varies from track to track. However, as mechanical stability puts an upper limit on the angular velocity (and not the linear velocity) this allows the full potential of the drive is used.

This hysteresis loop is generated at a constant angular velocity, as is the sinusoidal curve.
3, 0, 0) again with constant angular velocity [omega] = 0.
Both drives employ Constant Angular Velocity (CAV) disc rotation to enable faster data transfers from any place on the disc.
However, there is an interim step in technology that should not be ignored: the combination of constant linear velocity (CLV) and constant angular velocity (CAV) technology.
Combining figures 8 and 9 gives figure 10 which represents the relationship of the displacement of the rubber wheel and the deflection of the blade holder under a constant angular velocity.
In addition, data transfers are optimized through the drive's 256-K buffer and the use of Constant Angular Velocity (CAV) technology to minimize user wait time between commands.
The drive also features a 256-KB buffer and Partial Constant Angular Velocity (PCAV), which combines Constant Angular Velocity (CAV) and Constant Linear Velocity (CLV).
