ABSTRACT:
A motion picture film having digital audio data recorded in at least one sound track thereof. Such digital audio data includes a plurality of bytes of data each having 8 bits of data. Each respective bit of each byte of audio data is recorded in a sound track of the film in the film running direction and each byte is arranged side-by-side in a direction normal to the film running direction to form a compression processing block. C1 parity data is added to each such compression processing block and C2 parity data is added after a predetermined interval of plural compression processing blocks. Error correction may be performed by utilizing the C1 and C2 parity data for each compression processing block and at the predetermined interval of plural compression blocks.
