Zusammenfassung:The present invention provides a method and system for audio data retrieval from an optical media. The method includes reading a sector of audio data from the optical media, the sector comprising a sector data and a sector sub-code; collecting the sector sub-code; correcting any errors in the sector data in a fixed time period; calculating a time offset between a time for the collecting of the sector sub-code and the fixed time period; and matching the corrected sector data to the sector sub-code based on the calculated time offset. A method and system for retrieving audio data from an optical media has been disclosed. The present invention uses a fixed time period for the sector data error correction process. By using a fixed correction time, the sector data and the sector sub-code can be automatically matched based upon an offset calculated from the fixed correction time. In this manner, the sector data and its corresponding sector sub-code may be accurately matched without the need for complicated algorithms. This saves significant processing resources. The location from which the reading of the audio data is resumed is more accurately determined.
