Abstract

A digital signal recording disc has a first area and a second area. The second area differs from the first area. The first area stores a first-channel digital audio signal and a second-channel digital audio signal. The first-channel digital audio signal results from quantizing a first-channel analog audio signal with a first quantization bit number. The second-channel digital audio signal results from quantizing a second-channel analog audio signal with a second quantization bit number. The second area stores information of the first and second quantization bit numbers.
