RECORDING METHOD AND REPRODUCING METHOD FOR RECORDING MEDIUM, RECORDER AND REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a recording method for a recording medium that emits a converged laser beam to a recording layer of the recording medium to record information onto the recording layer and can enhance the utilizing efficiency of the laser beam emitted from a laser beam source. SOLUTION: The convergent layer beam in a circularly polarized light state is emitted to the recording layer RL of a magneto-optical recording medium MOD to heat the recording layer to the Curie temperature or over and an external magnetic field in response to information is given to a part of the recording layer RL heated to the Curie temperature or over to record the information onto the recording layer.
