摘要：Digital data consisting of different kinds of digital audio signals having samplingfrequencies, numbers of quantization bits and the like that are different from those ofthe two-channel digital audio signals, display data, program data, and the like arerecorded in the same signal format as that of the two-channel digital audio signals. Acode signal representing either of the two-channel digital audio signals and the digitaldata is recorded and control data indicative of the linear velocity of the digital disc uponreproduction are inserted in every frame of the recording signal. One block of the digitaldata is formed by a predetermined amount of data and the same control data used forcontrolling the processing of the digital data is recorded at least twice in one block. Thedigital disc is rotated at a constant linear velocity on the basis of the control data uponreproduction. The reproduced audio data from the reproducing circuit is D/A converted,and the pass band of the low-pass filter to which the reproduced analog audio signals aresupplied is adapted to the band of the reproduced analog audio signals.
