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： Good jitter is retained and recorded even when a linear velocity is variable. A recording parameter suitable for each of the linear velocities is obtained by performing test writings for an outer periphery zone of a disc at different linear velocities, and based on a correlation between each of the linear velocities and a recording parameter suitable for each of the linear velocities, a recording parameter corresponding to a linear velocity on an area onto which information is to be recorded is obtained.

摘要： A method for reproducing information from an optical medium including a substrate with grooves and lands alternately formed on the substrate in a radial direction. The grooves and the lands both serve as tracks which are divided into units in the circumferential direction. Each unit has a prepit area in a non-groove portion of the substrate with a first prepit being represented as VFO information in the prepit area and a second prepit being represented as address information in the prepit area. The first prepit and second prepit are located on both sides of a center line of one track and are arranged with respect to one another. The method includes irradiating an optical spot on the optical medium, detecting address information, controlling the irradiation position of the optical spot on the basis of the address information and reproducing information.
