摘要： An optical head provided with a light source, a heat-dissipating part, and a resin base mounted with them. The optical head has a light source, a heat-dissipating plate in contact with the light source, an objective, an objective driver, a photodetector, a sheetlike flexible circuit for feeding power to the light source and the photodetector and for transmitting a signal, and an optical bench holding at least the light source, the objective driver, the heat-dissipating part, and the photodetector. The heat-dissipating plate is in contact with a heat transfer part provided to the flexible circuit. The heat from the heat-dissipating plate is guided by the flexible circuit, and thereby the heat generated by the light source is dissipated through the flexible circuit and the heat-dissipating plate.

摘要： A magneto-optical recording/reproducing apparatus which comprises a first optical system (1) provided with a first objective lens (2), a second optical system (21) provided with a second objective lens (22) having a numerical aperture different from that of the first objective lens, and a magnetic head (19) that is provided close to a magneto-optical recording medium for recording and is driven together with the second objective lens (22) in a body. Even when either of a first and a second magneto-optical recording medium (41, 42) having recording densities different from each other is loaded in the magneto-optical recording/reproducing apparatus, the recording or reproducing thereof is possible. Therefore, the compatibility between the first and the second magneto-optical recording medium (41, 42) is obtained.
