Filed: 1989-04-14
Abstract: PURPOSE:To always obtain an optimum recording and erasing condition in the range of a use temperature and to prevent the quality of a reproducing signal from being deteriorated by attaching a temperature sensor to a magneto- optical recording medium or an optical head and controlling the intensity of a light spot according to the temperature in the vicinity of the medium. CONSTITUTION:A small-sized high-accuracy thermistor in a thin film or chip type is used as the temperature sensor 19, which is attached to the surface of the magneto-optical recording medium and the optical head. The output from the sensor 19 is fed back to laser driving circuit 11 through the metallic hub part 20 of the medium. The intensity of the light spot at the time of recording is allowed to be lower as the temperature gets higher and the intensity of the light spot at the time of erasing is allowed to be higher as the temperature gets lower. Thus, a recording bit is prevented from interfering with an adjacent bit caused by thermal diffusion with the excess intensity of the light spot at the time of recording. The quality of a rerecorded signal is prevented from being deteriorated, which occurs when data is not erased to be left by erasing the data with the intensity as high as a room temperature in the case of a low temperature.
