ABSTRACT:
A method for recording and reproducing compressed data to improve the utilization of the storage capacity of a moving recording medium. The data are compressed prior to a recording step. Prior to reproduction the data are expanded to retrieve the original data signal. To increase the storage capacity of the recording medium even further, the velocity of the recording medium is regulated as a function of the degree of compression. With a high degree of compression, a smaller velocity of the recording medium is selected, than with a low degree of compression.
