Patent ID: 8576678

Claim:
A system comprising: a control module configured to (i) transition a laser beam from a first position on an storage medium to a second position on the storage medium, (ii) based on a tracking signal, adjust a speed at which the laser beam is transitioned from the first position to the second position, and (ii) while the laser beam is transitioned from the first position to the second position, increase the speed at which the laser beam is transitioned from a first speed to a second speed; a plurality of error modules configured to (i) determine a track error of a current position of the laser beam, and (ii) estimate a depth of a groove on the storage medium; and a tracking module configured to while the speed at which the laser beam is transitioned is equal to the first speed, track the current position of the laser beam based on (i) the track error, and (ii) the depth of the groove, while the speed at which the laser beam is transitioned is equal to the second speed, track the current position of the laser beam based on the track error, and generate the tracking signal based on the current position.
