ABSTRACT:
A recording method for a disc-shaped recording medium formed by cementing two disc members having a recording layer on one surface, a diameter of approximately 12 cm and a thickness of approximately 0.6 mm, includes the steps of generating a digital audio signal that is generated by performing a .SIGMA..increment.-modulation for converting an analog audio signal with a sampling frequency set to a multiple of the standard compact disc sampling frequency fs=44.1 kHz, and recording the generated digital audio signal to the disc-shaped recording medium.
