摘要
An optical recording medium enables an optical pickup to quickly access a plurality of items of information progressing concurrently or to be selected simultaneously. By provision of spiral multitrack formed by multiple winding of a plurality of tracks in a first recording region and concentric-circle track formed in a second recording region adjacent to the first recording region, this invention can implement an optical recording medium in which the distance from the concentric-circle track to each track of the spiral multitrack is shortened, thus enabling an optical pickup to quickly access a desired track at a track jump.
