Magneto-optical recording medium, method of manufacturing magneto-optical recording medium, method of recording on magneto-optical recording medium, and method of reproduction from magneto-optical recording medium

摘要

A magneto-optical recording medium (10) comprises a recording layer (15) having columns extending in a lamination direction; and a first under layer which is placed below the recording layer and which functions as a nucleus for the columns. Independent claims are also included for: (a) manufacture of magneto-optical recording medium comprising a first under layer forming system; and a recording layer forming step on the first under layer; (b) a method of recording on magneto-optical recording medium comprising a data write step of writing predetermined data to the recording step; and (c) reproduction from a magneto-optical recording medium comprising a data readout step of reading out predetermined data written to the recording layer.
