Cd-r medium recording method

Abstract

Detection is made of an outermost track on a CD-R medium for which track-descriptive information is not yet recorded in a PMA area and track-specific recording data are already recorded in a program area by a track-at-once scheme. It is then determined whether recording on the outermost track is terminated at the end of a first-type area where a Q subcode INDEX is at a value of 0 or is made up to a second-type area where the Q subcode INDEX is at a value of 1 or greater. If the recording on the outermost track is terminated at the end of the first-type area represented by the Q subcode INDEX value 0, the track-specific recording data are additionally written onto the outermost track starting at the beginning of the second-type following the first-type area and the track-descriptive information for the outermost track is recorded into the PMA area. If the recording on the outermost track is made up to the second-type area represented by the Q subcode INDEX value 1 or greater, the track-descriptive information for the outermost track is recorded into the PMA area without the track-specific recording data being additionally written onto the outermost track. Such arrangements allow a main body of a music piece to be additionally written onto an outermost track which has only a blank segment or inter-music-piece signal recorded thereon.
