ABSTRACT:
A recording and/or reproducing apparatus for a recording medium such as an optical disc includes a head, a recording and/or reproduction control unit, an arithmetic operating unit and a display control unit. On the recording medium, management data for controlling recording of data recorded on a data recording area or the operation of recording and/or reproducing recorded data, and address data have been recorded. The head performs recording of data on the recording medium or reading out of recorded data therefrom. The recording and/or reproduction control unit records data on the recording medium discretely by the head, and reads out data discretely recorded on the recording medium as continuous data on the basis of the management data. The arithmetic operating unit arithmetically computes data representative of a reproduction position of data recorded in the data recording area of the recording medium. The display control unit allows the display unit to display the entire recording capacity of the recording area of the recording medium on the basis of the management data read out by the head, and allows the display means to display the reproduction position on the basis of data representative of a position calculated by the arithmetic operating unit.
