Abstract
A method of recording a pulse code modulation (PCM) audio on a digital versatile disc (DVD), comprising: inserting the DVD into the optical disc drive; utilizing the laser beam to write a PCM audio data to an audio contents area on the DVD; and writing a PCM audio data to an audio contents area on the DVD utilizing the laser beam, wherein the audio contents area is a fragment or a zone on the DVD, and wherein the DVD is either a DVD-R/-RW or a DVD+R/+RW corresponding to the audio contents area being the fragment or the zone, respectively The invention allows existing PCM audio data stored on a CD to be recorded on a DVD, and provides the playback of the recorded PCM audio data on the DVD.
Claims14
A method of recording a pulse code modulation (PCM) audio on a digital versatile disc (DVD), applied in an optical disc drive including an optical pick-up assembly, the method comprising:
- inserting the DVD into the optical disc drive;
- emitting a laser beam by the optical pick up assembly to focus on the DVD;
- and
- writing a PCM audio data to an audio contents area on the DVD utilizing the laser beam;
- wherein the audio contents area is a fragment or a zone on the DVD.
A DVD playback system, for playing a PCM audio data on a DVD, comprising:
- a button set, coupling to the controller, operable by a user to instruct commands;
- an optical pick-up assembly, for reading the DVD, the DVD comprising a plurality of audio contents areas;
- a controller, for utilizing the optical pick-up assembly to reproduce a PCM audio data from one of the audio contents areas on the DVD in response to the commands;
- a decoder, coupling to the controller, for reconstructing a decoded audio data from the PCM audio data;
- and
- an audio jack, coupling to the decoder, for outputting the decoded audio data;
- wherein the audio contents area is a fragment or a zone on the DVD.
A method of playing a PCM audio data stored on a DVD, the method comprising:
- receiving commands instructed by a user for playing the PCM audio data stored on the DVD, wherein the DVD comprises a plurality of audio contents area;
- accessing one of the audio contents areas on the DVD to reproduce the PCM audio data;
- reconstructing a decoded audio data from the PCM audio data;
- and
- outputting the decoded audio data for playing the same.
