Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 再生光が照射される記録膜の照射部位熱が蓄 積しない光磁気ディスク装置を提供する。 【構成】 レーザ光を光磁気記録媒体1の面上に照射す ることにより磁気光学効果を利用して情報の再生を行う 光磁気ディスク装置において、情報の再生時に、光磁気 記録媒体1に記録されたドメインの磁気的安定性を向上 させる放熱機構5を、光磁気記録媒体1に接触させて設 けた。 (57) [Abstract] [PROBLEMS] To provide a magneto-optical disk device in which heat of an irradiation site of a recording film irradiated with reproducing light is not accumulated. In a magneto-optical disk device that reproduces information by utilizing the magneto-optical effect by irradiating the surface of the magneto-optical recording medium 1 with laser light, information is recorded on the magneto-optical recording medium 1 at the time of reproduction. A heat dissipation mechanism 5 for improving the magnetic stability of the domain is provided in contact with the magneto-optical recording medium 1.
