METHOD FOR BUFFERING AUDIO DATA IN OPTICAL DISC SYSTEMS IN CASE OF MECHANICAL SHOCKS OR VIBRATIONS

摘要

Method for buffering audio data in optical recording media, and apparatus using such method for reading from and/or writing to optical recording media in case of an error condition (e.g. upon shock or vibration). It comprises the steps of, as audio data is read from a position on the medium prior to a position corresponding to a verified write position in the memory (9) and in case writing to the memory is inhibited; counting the number of samples read; searching for two subsequent markers distant of one frame (to take into account the case where a marker could be corrupted); determining the remaining distance to the verified write position based on the sample count; restarting writing the audio data to the memory when the data read from the medium corresponds to the verified write position.
