摘要： Before original information is recorded in areas such as a recording medium management area where the same pattern of information is recorded many times, a dummy pattern that minimizes a recording film flow is recorded. Because the direction of the recording film flow depends on the length of a mark length, the dummy pattern is a pattern including marks with a unique length. Randomly or sequentially selecting and recording a plurality of dummy patterns, each with a recording film flow direction different from others, prevents jitters, which will be caused by the recording film flow, from increasing.

摘要： An optical reproducing method for an optical medium including a disk-like substrate having a plurality of tracks associated with a plurality of grooves. A plurality of zones are provided with each zone including at least two tracks. Radially adjacent units of a respective zone are delimited by a pair of radial lines joined to form a central angle at an apex proximate to a center of the disk-like substrate with each unit of a respective zone being delimited by the same central angle and units of different zones being delimited by different central angles. The grooves are wobbled in the radial direction and the length is the same for the different zones. The method includes irradiating an optical spot on the optical medium, detecting a reflected beam from the optical medium, and reproducing information on the optical medium by using a signal obtained by the reflected beam.
