A disc, such as the floppy disc, the compact disc, or either of the compact discs of the hard discs may be divided or formatted into a number of usable tracks and sectors. The other areas between the usable tracks are unformatted and unusable. An actuating or driving program may be used to actuate the recording head to process and record the unformatted or unusable areas of the disc. The actuating program may be directly introduced into the memory of the hard disc or of the computer, or may be stored in an independent working station.
