摘要
Irradiated with light with a predetermined intensity for reproduction, is transferred to the reproducing magnetic field to the information recording layer reproducing layer by applying, magneto-optical memory that can be used for magneto-optical storage medium which make the above information is available reproduction included in a predetermined area in the apparatus, by controlling a permanent magnet for applying an optical head and a reproducing magnetic field reproducing the information, to calculate the reproduction error rate according to the reproduction based on the reproduction error rate having a control unit for changing the intensity of the reproducing magnetic field characterized in that the light provide a magnetic storage apparatus and reproducing method. By using a permanent magnet, it is possible to reduce the heat generation, it is possible to suppress an increase in reproducing magnetic field strength at a high temperature. In addition, by displacing the permanent magnets, it can be in an area that requires more and more the magnetic field upon reproduction as to efficiently give the highest part of the magnetic flux density of the permanent magnet. ; Magneto-optical storage device, a reproduction error rate, the permanent magnet, heating value, the reproducing magnetic field intensity
