| Title of Invention | METHOD FOR READING A DUAL-LAYER RECORDING MEDIUM |
|---|---|
| Abstract | The present invention relates to a method and an apparatus for reading a magneto-optical recording medium comprising a first storage layer and a second storage layer and a read-out layer, wherein an expanded domain leading to a read-out pulse is generated in the read-out layer by copying a mark region from the first or second storage layer to the read-out layer through heating by a radiation power and with the help of an external magnetic field. The radiation power is set to a first value for reading from the first storage layer and to a second value for reading from the second storage layer. A parameter indicating crosstalk between the first and second storage layers is determined during a reading operation, and the radiation power is then controlled on the basis of the determined parameter. Hence, crosstalk between the first and second storage layers can be reduced by keeping the read-out temperature close to the compensation temperature of the other storage layer which is not read. The invention further relates to a recording medium for use in said method and apparatus. |
