Abstract:
A digital recording apparatus employing a tape-shaped recording medium having formed thereon a plurality of slanted tracks corresponding to digital information signals of two channels, comprising:a signal processing unit for separating one of the two channels of the digital information signals into first upper order bits and first lower order bits and for separating the other channel of the digital signals into second upper order bits and second lower order bits, said signal processing unit separating said first lower order bits and said second lower order bits into respective upper order side bits and lower order side bits; anda recording unit for recording an output of said signal processing unit on the tape-shaped recording medium, said recording unit having a rotary drum and at least one head mounted on said rotary drum, said recording unit causing said at least one head to record said first and second upper order bits, said upper order side bits of said first lower order bits, said upper order side bits of the second lower order bits, said lower order side bits of said first lower order bits and said lower order side bits of the second lower order bits from said signal processing unit as different tracks,wherein said signal processing unit outputs the lower order side bits of said first lower order bits with a portion of the first upper order bits and the lower order side bits of said second lower order bits with a portion of the second upper order bits as one data, said recording unit causing said at least one head to record said one data on the tape-shaped recording medium to form a track.
