Abstract
A disk drive resumes supplying audio information without the hesitation normally attributed to disk access time. Initially, an indication is received that the disk drive should be deactivated. Next, audio information is stored from a beginning position, where audio information was last provided, to a resume position. Then, the resume position at which the disk drive should begin retrieving audio information, when the disk drive is reactivated, is stored. Finally, the disk drive is deactivated. In this manner, when the disk drive is reactivated, the stored audio information is supplied without the hesitation normally attributed to the disk access time of the disk drive.
