The present invention provides a method for reducing the amount of power consumed
by an optical disk player. The method provides: recording at least a portion of
the audio, video, or audio/video data from an optical disk onto the portable computer's
hard disk while the optical disk is being played over the output device; turning
the drive's spin motor off as soon as the data has been transferred to the hard
disk; and then continuing to play the remaining un-played portion of the optical
disk over the portable computer's speaker or other output device from the hard
disk. The method further comprises recording in an index database a title of the
optical disk and a title of the track written to the hard disk, and playing the
data from the hard disk without re-reading the optical disk if the data has been
previously written to the hard disk.
