Abstract
The present invention is a method and system to provide step motor control in an optical storage medium. The system comprises a light source that generates a beam of light and an optical disk that reflects the beam of light. The optical disk has a plurality of tracks. The system further comprises a detector for receiving the reflected beam and a control circuit coupled to the detector. The control circuit provides a step signal in response to the reflected beam. The step signal has a value corresponding to an operational mode of the control circuit. A step motor coupled to the control circuit and the light source drives the light source across the disk by a predetermined step based on the step signal.
