The prepits of the first and second portions are arranged at every two-track pitch in the radial direction and are arranged with one track displaced in the radial direction with a gap being provided between the first and second prepit portions. The method includes providing the optical medium, and recording information on the optical medium by irradiating an optical spot thereon.
