ABSTRACT:
In a recording method for a recording medium having a data recording area on which a data recording and/or reproducing operation is carried out, and a management data area on which management data to manage a recording and/or reproducing operation for the recording medium are recorded, when new data are recorded on the recording medium in a state where data have been already recorded on the recording medium and a data-recordable area on which the new data can be recorded exists on the data recording area, the recording operation of the new data is started from the head position of the data-recordable area on the basis of the management data recorded on the management data area, and data which have been already recorded on the recording medium are deleted by the same data amount as the new data to be recorded on the data-recordable area from a position on the data recording area of the recording medium at which the recording operation is instructed to start.
