Abstract

Digital recording and reproducing apparatus is disclosed for recording digital signals in such a manner as to conceal errors contained therein, including a write address generator for storing incoming digital signals in a first sequence in a memory, and a read address generator for causing the signals to be read out from the memory in a second sequence different from the first sequence. A control device selectively connects the write address generator and the read address generator sequentially to the memory, whereby the digital signals read out from the memory may be recorded on a recording medium.
