Constant Angular Velocity (CAV) Recording Technology The CRW-5232AS drive employs the Constant Angular Velocity (CAV) recording method. With CAV recording, the drive spindle motor rotates the disc at the same speed regardless of the radial position of the pickup head. This means that there is a higher transfer rate when writing data to the outer tracks of the disc than to the inner tracks, as the head traverses a longer linear path on the outer than the inner part of the disc. Although the transfer rates vary, and may not be at maximum, depending on the part of the disc being written to, the CAV method allows faster recording speed because the rotation speed does not have to change when the head writes data to different areas of the disc. This is primarily advantageous for computer applications. 20 ASUS CRW-5232AS
