ABSTRACT:
An image recording/reproducing apparatus includes a first device for reproducing data from a recording medium, a second device for recording the data reproduced by the first device, a data maintenance unit for controlling the operation of the first and the second devices, a power supply unit for supplying a power to the first and the second devices, a power control unit for controlling operation of the power supply unit, an error data detecting unit for detecting an error data among the data recorded in the second device, and a main control unit, which, upon receiving a power cut-off command, controls the data maintenance unit to stop the operation of the second device and delete the error data detected by the error data detecting unit. Then, with the deletion of the error data, the main control unit controls power control unit so that the power supply unit cuts off the power supply. With the input of the power-off command, error data is detected among the data recorded in the recording space of the hard disc drive and deleted. Accordingly, the system is always maintained at an optimum state.
