Claims
- 1. A PCM signal recording apparatus for recording PCM data on a recording medium in which PCM data and N-blocks of sub-code data are received from a reproducing device which reproduces said PCM data, and said N-blocks of sub-code data prepared by recording N-blocks of identical sub-code data repeatedly N-times in order to add auxiliary information to said PCM data and produces at least N flags indicative of whether said N-blocks of sub-code data are respectively correct, comprising:
- reception means for receiving said N-blocks of sub-code data and said N flags;
- decision means for deciding whether said N flags received by said reception means indicate whether said N-blocks of sub-code data are respectively correct; and
- recording means for recording at least said PCM data and said N-blocks of sub-code data;
- said recording means being provided for replacing sub-code data which is decided as being erroneous by said decision means, among said N-blocks or sub-code data received by said reception means, with sub-code data which is decided as being correct by said decision means and for recording sub-code data which is decided as being correct by said decision means repeatedly M-times, where M.ltoreq.N and where M and N are integers.
- 2. A PCM signal recording apparatus according to claim 1 wherein one sub-code data which is decided to be correct by said decision means through one of said flags is recorded repeatedly N-times.
