# constant angular velocity

- constant angular velocity
Abbreviated **CAV**. An unchanging speed of rotation. Hard disks use a CAV encoding scheme. The constant rate of rotation means that sectors on the disk are at the maximum density along the inside track of the disk. As the read/write heads move outward, the sectors must spread out to cover the increased track circumference, and therefore the datatransfer rate falls off.
