ABSTRACT:
The present invention relates to a data recording/reproducing apparatus (1), which includes a reader (3) for reading content data recorded in a minidisc (2), and a controller (4) for generating one file by gathering a plurality of content units not continued with each other to the read contents data and executing a process for generating relative position information of each content unit when the file is generated. The controller further divides the content unit into parts at a discontinuous point if each content unit for constituting the generated file includes a discontinuous area on a recording medium in case of reading the relative position information by the reader, and generates absolute position information on the recording media of each part. The relative position information of the content unit for constituting the read file and the absolute position information of the parts are stored in a table memory (6). The read file is expanded in an expansion memory (7) as temporary storage means by the parts and the absolute position information, and the expanded parts are subjected to an editing process including any of dividing, combining, erasing, track number moving by a data editor (8).
