PURPOSE:To prevent missing of information at the editing point, by constituting a connection for edition to be made only in the section of a parity frame group. CONSTITUTION:The digital signal input to the input terminal 1 is distributed with the order arranging circuit 2 according to the number of recording tracks. In the compression memory 3, the time spacing in which frame synchronism pattern, circulating code CRC, and parity word can be inserted is provided. The synchronizing pattern S for the data frame is produced at the synchronizing pattern generator 10 and the synchronizing pattern S' of the parity frame S' is generated at the synchronizing pattern generator 11, and they are switched at the switch 12 and inserted to the specified position of the specified frame with the mixer 9. The gate circuit 13 outputs the recording signal series to be obtained at the recording signal output terminal 14. With the constitution like this, the missing and error of information at the edit point are avoided. |
