ABSTRACT:
A tracking access control method for an optical storage medium drive is used for reading data stored in an optical storage medium. The optical storage medium drive has a sled capable of sliding in a radial direction of the optical storage medium. The method is capable of exerting a brake force on the sled according to a sliding speed of the sled relative to the optical storage medium when the sled is located at an intermediate position in a sliding course from an initial position to a target position on the optical storage medium.
