Main data and subdata are subjected to an error correction encoding process in each of ECC encoders 2 a and 2 b. The main data is modulated by an 8-16 modulating unit 3 . In a sync signal adding unit 7 , selected ones of a plurality of patterns are added as sync signals on the basis of conversion tables stored in a table memory 4 . In a predetermined interval on an optical disc, a switch 13 is turned on and selection of the patterns of the sync signals is controlled in accordance with a value of the subdata, so that the subdata is recorded. A recording signal of an EFM Plus frame format is generated from the sync signal adding unit 7 . The recording signal is supplied to an optical pickup 9 through a recording circuit 8 . The main data and subdata are recorded onto an optical disc 10.
