A method of recording a digital signal representing digital data onto a recording medium by changing a position of each edge of each of a plurality of pits in accordance with the digital signal is provided. The method has the processes of: receiving a digital signal to be recorded; generating a predicted inter-symbol interference signal by predicting inter-symbol interference contained in a reproduced signal from the recording medium when a reproducing process is carried out with respect to the recording medium by a reproducing apparatus, on the basis of predetermined characteristics of a recording process in a recording apparatus, predetermined characteristics of the reproducing process, and the received digital signal; generating a compensated digital signal by subtracting the predicted inter-symbol interference signal from the received digital signal; and recording the compensated digital signal onto the recording medium by continuously changing the position of each edge of each of the plurality of pits in proportion to the compensated digital signal.
