-87- ABSTRACT OF THE DISCLOSURE A method of simultaneously recording and reproducing a digital audio signal and a digital video signal for a dynamic picture. A digital signal is recorded and reproduced in N bits (N: integer), and an image area, an audio area and a control area are formed by part of the N bits. Compressed digital video signals for multiple screens forming a dynamic picture are allocated in the image area in each compression reference period. A digital audio signal in each compression reference period is allocated in the audio area in the compression reference period. Data, such as compression information. which concerns a digital signal to be allocated in the image area or audio area, is allocated in the control area. As a digital video signal carrying a vast amount of information is recorded in a compressed manner, and the compression information is recorded at the same time, recording and reproducing the digital video signal for a dynamic picture can be executed without problems.
