OPTICAL INFORMATION RECORDING MEDIUM, OPTICAL INFORMATION RECORDING APPARATUS, AND OPTICAL INFORMATION RECORDING METHOD

摘要

An optical information recording medium includes a recording layer in which a track is formed, the track having recording marks linearly arranged thereon. Each recording mark has a dimension corresponding to a reference mark length, which serves as a reference, in a track direction along which the track extends, the dimension being smaller than dimensions of the recording mark in two directions perpendicular to the track direction.
