    摘要: A recording apparatus for recording information to an optical recording medium having grooves and lands alternately provided in a radial direction, information recording areas being formed in both of the grooves and the lands, and at least one prepit region where no grooves is formed. In the prepit region, first and second information marks are disposed on a virtual extension of respectively a first boundary between one groove and one adjacent land a second boundary between the one groove and an other adjacent land, the first and second information marks being disposed so as not to exist at opposing positions on both of the first and second boundaries of the one groove. The apparatus includes an irradiation source for irradiating a light spot on the optical recording medium, and a controller for controlling an irradiation position of an optical spot from the irradiation source.

    摘要: An optical reproducing method using an optical recording medium having an aligned prepit portion straddled on a plurality of tracks in a radial direction which includes a first and a second prepit portion divided in a track direction. The respective first and second prepit portion are arranged on a boundary of respective tracks and include a synchronous information prepit arranged at every two-track pitch in the radial direction and positioned at opposite boundaries of the same track. A trailing end of the first prepit portion is aligned with the radial direction in arrangement. the method includes irradiating an optical spot on the optical recording medium, detecting a reflected beam from the optical recording medium, and reproducing information on the optical recording medium by using a signal obtained in accordance with the reflected beam.
