ABSTRACT:
A dual disc recording/reproducing apparatus and recording method. The apparatus includes a reproducing deck unit and a recording/reproducing deck unit with both being controlled by one control unit. The method comprises the steps of recording on a disc a first program and a disc playing time on the lead-in area thereof unless data is recorded on the disc, recording the data onto the next recording area of the lead-out area if data is already recorded on the disc, and then recording the lead-out to process a present lead-out area as a bad block area. The next step is recording a new lead-out at the end of the disc playing time, and then processing the previous and next blocks, including the present lead-out area, as a bad block during the recording of the data, processing the previous and next blocks, including the lead-in area, as a bad block, and then recording the data in the program memory area onto a new lead-in area.
