ABSTRACT:
An apparatus which includes a recording or reproducing unit for recording or reproducing data on or from a disc, a data transmission/reception unit for transmitting playback data reproduced by the recording and reproducing unit from the disc to an external computer and receiving recording data supplied from the computer for supplying the received recording data to the recording and reproducing unit, a system controller for receiving a command supplied from the computer for controlling the data receiving unit, a temperature sensor for detecting the temperature within a main body of the disc recording and reproducing apparatus, and a recording/playback controller for controlling the operation of the recording and reproducing unit responsive to the command supplied from the computer via the system controller and a detection output of the temperature sensor. The recording/playback controller initially decides, when a command is supplied via the system controller from the computer, whether or not the temperature within the main body of the apparatus is outside a pre-set temperature range and inhibits the recording or reproducing operation when the temperature is outside the pre-set temperature range before starting the recording or reproducing operation. Further, if, during recording or reproducing it is detected that the temperature is outside of the pre-set temperature range, the recording/playback controller terminates the recording or reproducing operation after first recording or reproducing a pre-set amount of the recording or playback data, respectively, conforming to the command from the computer.
