Partial Constant Angular Velocity (P-CAV) Recording Technology

The Partial Constant Angular Velocity (P-CAV) recording method is a combination of
the Constant Angular Velocity (CAV) and Constant Linear Velocity (CLV) recording
technologies. In CAV recording technology, the drive maintains a consistent rotation
speed which will result in a variable transfer rate, while in CLV recording technology,
the data transfer rate is kept at a fixed level by changing the rotation speed.

P-CAV recording
technology switches from
CAV to CLV once the
maximum transfer rate is
reached. Unlike Zone
Constant Linear Velocity (Z-
CLV) recording, no links are
produced in the P-CAV
recording process, resulting
in a higher average transfer
rate.

The following illustration
shows the Partial Constant
Angular Velocity (P-CAV)
recording technology.
