PURPOSE:To convert and record a bit of information based on a first format to a bit of information based on a second format by detecting the changing point of a bit of first sub-code information with a sub-code information generating means for the first sub-code information excluding TOC information and generating a bit of second sub-code information based on a detecting flag. CONSTITUTION:At sub-code information generating sources 2-5, the first sub- code information including TOC (table of contents) information, namely, corresponding to a CD format is generated, processed by a processing means 9 and based on the output signal, the second sub-code information corresponding to a DAT format is generated by a sub-code information generating means 17. Then, the first sub-code information excluding the TOC information detects the changing point and based on the detecting flag, the second sub-code information is generated. The TOC information is converted to the second sub-code information by the processing means 9 and outputted through the sub-code information generating means 17. In a recording means 8, the second sub-code information is recorded together with a bit of main information.
