ABSTRACT:
In a rotary-head digital audio tape system, a reproduced digital signal contains audio data, parities P for the audio data, and parities Q for the parities P and the audio data. The reproduced digital signal is sequentially written in a memory. A code error correction circuit reads the digital signal from the memory and performs code error correction of the digital signal by use of the parities P and Q. The code error correction circuit includes a device for, during the code error correction using the parities P, reading the whole of the written digital signal from the memory. The code error correction circuit includes a device for, during code error correction using the parities Q, reading only the audio data and the parities Q corresponding to the audio data from the memory.
