Abstract
Abstract A recording and/or reproducing apparatus into which a disc cartridge (2) accommodating a disc (1) is loaded and in which information signals are adapted to be recorded on or reproduced from the disc (1). A temperature sensor (20) is provided within the apparatus for contacting with and sensing the temperature of the disc cartridge (2). By this temperature sensor (20), the temperature of the loaded disc cartridge (2) is sensed and an output of a light source (10) of an optical head is controlled on the basis of the sensor output to effect recording and/or reproduction of the information signals under an optimum operating state.
