Abstract
An optical information recording medium includes a track storing information in a plurality of sectors, wherein the track is formed spirally or concentrically. One sector includes a plurality of frames and one frame includes a resync mark region, a frame address region, an information region, and a postamble region. In the information region in the first frame, identification information for identifying the position of the sector is stored. In the information region in each frame, information obtained as a result of scrambling performed based on a value of the identification information is stored.
