Video and audio recording with audio being recorded in plural channels independently of video on different recording media

Video and audio recording and reproducing apparatus for recording video data and audio data on a video recording medium and on separate audio recording media, respectively, and reproducing video data and audio data from said video recording medium and said respective audio recording media, comprising;

• a video data recording unit for writing video data on and reading video data from a nonlinear accessible video recording medium;
• an audio data recording unit for writing audio data provided in plural audio channels on and reading audio data from nonlinear accessible audio recording media different from said video recording medium, said audio data recording unit operating independently of said video data recording unit;
• and
• said audio data recording unit being comprised of plural pairs of recording units, each pair being associated with a respective one audio channel such that audio data in a particular audio channel is recorded on a particular pair of recording units associated with that particular audio channel, and each pair including first and second recording units for writing only audio data of said particular audio channel identically on both said first and second recording units of a respective pair, a fault detector for detecting a fault in a recording unit of said respective pair and a reader for reading audio data from the recording unit in said pair that is determined not to exhibit a fault.

A method of recording video data and audio data on a video recording medium and on separate audio recording media, respectively, and reproducing video data and audio data from said video recording medium and said respective audio recording media, comprising the steps of:

• receiving multiplexed audio data and video data in predetermined serial format;
• separating the audio data and the video data from the received serial format multiplexed data;
• temporarily storing the separated audio data;
• writing the video data on and reading video data from a nonlinear accessible video recording medium;
• writing the audio data provided in plural audio channels on and reading audio data from nonlinear accessible audio recording media different from said video recording medium, said writing and reading of audio data being independent of the writing and reading of said video data;
• and
• controlling the writing onto the audio recording media of the temporarily stored audio data.

A method of recording video data and audio data on a video recording medium and on separate audio recording media, respectively, and reproducing video data and audio data from said video recording medium and said respective audio recording media, comprising the steps of:

• writing video data on and reading video data from a nonlinear accessible video recording medium;
• writing audio data provided in plural audio channels on and reading audio data from nonlinear accessible audio recording media different from said video recording medium, said writing and reading of audio data being independent of the writing and reading of said video data, wherein only audio data of a particular channel is written, identically, on both first and second recording units of a pair of recording units associated with said particular audio channel;
• detecting a fault in a recording unit of a respective pair;
• and
• reading audio data from the recording unit in said pair that is determined not to exhibit a fault.
