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.

It's remarkable 48X write speed enables a full CD-R to be burned in less than two and a half minutes, and because veloCD utilizes the Constant Angular Velocity (CAV) method of writing to disk, unlike drives that use Constant Linear Velocity (CLV) technology, CD recording performance is smoother, with less chance of write errors.
Drive shaft depending on whether constant angular velocity rotates or not can be divided into CV drive shaft and non-CV drive shaft.
The OTI-9510 also provides full support for the latest Constant Angular Velocity (CAV) operation, which permits faster and more reliable disc writing with significantly quieter drive operation.
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.
The 72X TrueX reads 7 tracks of data in parallel and employs Partial Constant Angular Velocity (PCAV) for optimum performance.
It is one of the first 48X drive on retail shelves using the Constant Angular Velocity (CAV) recording method, the fastest method available.
The drive uses constant angular velocity (CAV), which technically gives DVD+RW a throughput advantage over DVD-RAM.
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 obtain the best performance in the industry while allowing a high degree of programmability and flexibility in the implementation of CD-R and CD-RW write strategies, the OTI-9797 employs dynamic write strategy, plus partial and full Constant Angular Velocity (CAV) write and audio DAC/filter circuits.
Cirrus Logic's ADB technology is also extremely important for the newer constant angular velocity (CAV) drives, where the transfer rate will no longer be constant and will vary dramatically based on whether the optical read head is reading from the inner or outer track of the CD.
