发明名称 Magneto-optical recording media and magneto-optical recording device using the same
摘要 This invention provides a magneto-optical recording medium comprising at least an information storage layer and a readout layer disposed on the substrate, the information storage layer being used to record information by changing the magnetized state by raising the temperature thereof by light irradiation, and the readout layer being capable of copying information recorded on the above-mentioned information storage layer, located closer to the substrate than the above-mentioned information storage layer, and having a coercive force of 3 kOe or less at room temperature. By using this recording medium, a Signal to Noise ratio can be obtained in reproduction without deterioration of the information recording characteristics.
