Abstract
A recording and/or reproducing apparatus into which a disc cartridge accommodating a disc is loaded and in which information signals are adapted to be recorded on or reproduced from the disc. A temperature sensor is provided within the apparatus for contacting with and sensing the temperature of the disc cartridge. By this temperature sensor, the temperature of the loaded disc cartridge is sensed and an output of a light source 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.
