Abstract: Disclosed is an optical information recording medium that can solve a problem that a BCA mark becomes unrecognizable in an optical recording medium including a recording layer using an organic coloring matter. A playback signal in a burst cut area comprises a bright-area amplitude level formed upon the playback of a part where no barcode-shaped mark has been formed, a dark-area amplitude level formed upon the playback of a part where a barcode-shaped mark has been formed, and a maximum amplitude level having a protruded waveform formed upon the reproduction of the edge of a barcode-shaped mark. When a portion intermediate between the maximum amplitude level and the dark-part amplitude level is defined as an intermediate level, the intermediate level is lower than the bright-area amplitude level.
