Definitions for "Constant Angular Velocity"
A DVD recording style; the laser pick-up moves at the same speed over the disc surface, from the center towards the exterior-margin. With every rotation, no matter its diameter, the same amount of information is written.
Constant Angular Velocity is a term describing how a media disk rotates throughout playing. The motor speed of the media player stays the same throughout the path of the read / write head.
(CAV) An unchanging speed of rotation. Hard disks use a constant angular velocity encoding scheme, where the disk rotates at a constant rate. This means that sectors on the disk are at the maximum density along the inside track of the disk; as the read/write heads move outwords, the sectors must spread out to cover the increased track circumference , and therefore the data transfer rate falls off.
A buffer memory mechanism that prevents its portable audio equipment from skipping under most conditions. The technology recovers laser position 10 times faster than previous designs; so it can withstand the impact of jogging (and other sports).
