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.

Method for the recording and reproducing of data

A compact disc recorder and/or playback unit in which a display is provided at an operational side of the set for displaying data that is intended for operation use of single record operation. A static and a dynamic display are provided. The dynamic display is related to the performance of searches or selection operations, and has a flow of motion of data elements related to search for selection operations that are arranged perpendicular to each other in respect to their direction of motion. Title or track search is carried out horizontally according to a horizontal plane of motion of a pick-up. Magazine compartment search is carried out vertically according to a vertical plane of motion corresponding to a direction of a record gripper or record lift, when using a magazine having record compartments one above the other.
