摘要: A method for reproducing information from an optical medium including a substrate with grooves and lands serving as recording tracks alternately formed on the substrate in a radial direction, the recording tracks are divided into recording units in the circumferential direction and each recording unit has a prepit area in a non-groove portion of the substrate including a first prepit representative of VFO information and a second prepit representative of address information. The first prepit and second prepit are located on both sides of a center line of one track and formed on each side of the center line of the one track so as to be shared with an adjacent track adjacent the one side of the center line of the track, and every prepit does not exist at opposing positions on both sides of the center line of one track. Information recorded on the optical medium is reproduced.
