PURPOSE:To minimize the number of data which become uncorrectable by distributing and recording PCM data on plural tracks and reducing a recording band per track. CONSTITUTION:The output of a counter 27 is inputted to a corrected-word generating circuit 22, decoder 29, and counter 28. The generating circuit 22 generates a corrected word according to the output of the counter 27. A P signal output 31 is connected to the data latch 23 of the 1st track and a Q signal output 32 is connected to the data latch 23 of the 8th track. Data latches 23 of respective tracks latch data or corrected works according to the output of the decoder 29. An error detection signal generating circuit 24 read data out of data latches 24 to generate an error detection signal on the basis of those data, outputting data and an error detection signal successively. An MPX26 performs switching between the output of the error detection signal generating circuit 24 and a synchronizing signal generated by a synchronizing signal generating circuit 25. |
