摘要:
An optical information recording method includes the following steps. A converting step is converting a light beam into an information beam carrying information by using a spatial beam modulator. A focusing step is focusing the information beam on an optical information recording medium including an information recording layer. An irradiating step is irradiating the optical information recording medium with a reference beam and the information beam so that the reference beam and the information beam intersect with each other on the information recording layer by using an optical component. A rotating step is rotating the optical information recording medium or the optical component by using a drive unit for performing angle-multiplex recording. A management information recording step is recording management information at two or more relative angles having an angle interval smaller than twice at least a first null angle.
