In a method and an apparatus for recording a user's table-of-contents information concerning program data on an erasable and rewritable-type optical disc, a system control section records a new program data in a predetermined area of an optical disc and stores address information concerning a record start position and a record stop position of the predetermined area recorded the program data in a recording medium. System control section detects a track including the record start position and the record stop position and converts an address of a start position and a stop position of the track including the record start position into the address of the record start position and the record stop position. Also, system control section converts track numbers M+1, M+2, M+3. of tracks following a track M including the record stop position into new track numbers N+1, N+2, N+3, respectively. At this time, the M is the track number of track including the record stop position, the N is the track number of track including the record start position. System control section records the track numbers of the tracks whose track numbers are newly set, the address of the start position, and the address of the stop position on the user's table-of-contents.
