An image data filing apparatus is provided with a main device which records and/or reproduces image data with respect to the recording medium being set therein, a terminal device which is connected to the main device by communication line and which records and/or reproduces image data with respect to the recording medium in the main device, a plurality of buffer memories for temporarily storing the image data to be recorded to the recording medium or the image data reproduced from the recording medium, and control device which performs a multi-processing of recording operation or reproducing operation of the buffer memories. When a request from the main device and a request from the terminal device are simultaneously generated, according to those requests, the multi-processing is performed by the control device, as a result, those requests can simultaneously be processed.
