Abstract

PURPOSE: To prevent the noise occurrence caused at tape edit part, by using the error detection code.
CONSTITUTION: The input audio signal is in A/D conversion 1, it is sectioned by taking m sample as one frame, error detection code is added to at the error detection code generation circuit 2 every one frame, the synchronizing signal is added at the synchronizing signal generation circuit 3, and it is recorded on the tape 5 through the write-in head 4. In this case, one sample n-bit is parallelly recorded on the tracks 1 to n of n sets arranged broadwise the tape 5, and the audio data b, of m sample, error detection code c, and synchronizing signal a are located. The n-bit for one sample audio data's share is recorded as b' column longitudinally. At reproduction, if erro is taken place to the digital signal, the reproduced analog signal is interrupted with the detection of the error detection code.
