Abstract
Improved control of spindle speed during optical media seek operations is provided by adjusting the spindle motor speed during the actual optical pickup unit movement. In response to receiving a seek instruction to move an optical pickup unit to a target position, the current signal frequency corresponding to a current spindle motor speed may be determined. A target signal frequency corresponding to a desired spindle motor speed at the target position may also be computed. Thereafter, the current spindle motor speed may be adjusted towards the desired spindle motor speed prior to the optical pickup unit reaching the target position.
