    摘要： An optical recording apparatus having a light source and an optical system. The medium is a substrate in the form of a substantially circular disk with grooves and lands alternately formed on the substrate in a radial direction. The grooves and lands both serve as recording tracks which are divided into recording units in a circumferential direction. Each recording unit has an address area devoid of the grooves including first and second address information. The first address information is formed on a first boundary between one track and an adjacent track on one side of the one track, and the second address information is formed on a second boundary between the one track and an adjacent track on an other side of the one track with the first address information and the second address information not existing at opposing positions on the boundaries of the one track.

    摘要： An optical recording/reproducing method and apparatus for use with an optical recording medium to which grooves and lands are formed on a substrate. Information recording areas are formed in association with both a groove and a land and an address area is formed at the information recording area preceding the groove and the land. VFO and address information are represented by pits which are disposed on an extension of the boundary between said groove and said land. The pits represents the VFO and address information and are disposed to satisfy such requirements that the pits are disposed alternately on both sides of an extension of the center line of one groove, that the pits are disposed alternately on both sides of an extension of the center line of one land, that the pits do not exist on both sides of a position on an extension of the center line of the groove and that the pits do not exist on both sides of a position on an extension of the center line of the land. The method and apparatus include features of irradiating an optical spot onto the said optical recording medium, detecting a reflected beam from the optical recording medium, detecting a VFO signal from the reflected beam indicative of the VFO information, detecting an amplitude of the VFO signal, and controlling an irradiation position of the optical spot on the basis of the amplitude utilizing appropriate apparatus.

    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.
