ABSTRACT:
A recording method for an optical medium having an aligned prepit portion straddled on a plurality of tracks in a radial direction, the prepit portion including a first and a second prepit portion divided in a track direction with respective first and second prepit portions being arranged on a boundary of the respective tracks. The first prepit portion includes a synchronous information prepit and the second prepit portion includes a synchronous information prepit which are arranged at every two-track pitch in the radial direction and arranged at opposite boundaries of the same track. A trailing end of the first prepit portion is aligned with the radial direction in the arrangement. The method includes providing the optical medium, and recording information on the optical medium by irradiating an optical spot thereon.
