Records or derives the compressed audio data in the audio RAM through the interface unit, and if the interrupt signal is output from the interface unit, sequentially determines whether the next block is a bad block and writes or reads the data in a good block. The shipment is made up of a digital processor, so even when recording a compressed audio signal using a defective audio RAM, it is possible to avoid defective storage and to store it. To read complete data Relates to an apparatus for recording / reproducing a compressed audio signal using a bad memory element and a method thereof.
