摘要
A magneto-optical storage apparatus and a reproducing method are provided. The magneto-optical storage apparatus is capable of using a magneto-optical storage medium provided with recording layer and reproducing layer. In the magneto-optical storage medium, information in the recording layer is transferred to the reproducing layer through irradiation of light at a given intensity for reproduction and through application of a reproductive magnetic field. The information contained in a given area thereof is enabled to be reproduced. The apparatus includes: an optical head irradiating light to the given area at least at a given intensity for reproduction; a permanent magnet applying at least the reproductive magnetic field to the given area; and a control unit controlling the optical head and the permanent magnet to reproduce the information, calculating a reproductive error rate associated with the reproduction and altering the strength of the reproductive magnetic field based on the reproductive error rate.
