Abstract
A control system controls the spin speed of optical media in an optical disc drive, wherein the optical media comprises a premastered area that cannot be overwritten and a user-writeable area that can be overwritten. The control system stops and starts the spinning of the optical media, and controls the spin speed and the direction of spin. The control system also determines whether the commanded spin speed has been attained within a specified time period, and maintains the commanded spin speed. An event issues when the commanded spin speed was not attained within a specified time period, when a problem is detected while attempting to maintain the commanded spin speed, and when the optical media stops spinning. A laser in the disc drive is turned off when spin is turned off.
