Abstract

A process and apparatus for transferring information between an information store and a data channel. During the recording process, the quantity of information to be recorded and, in the reading process, the capacity of an apparatus associated with the data channel to be fed with the information read, is determined and, based upon the quantity of information determined in each case, the control magnitude is produced to drive the information store at a predetermined speed. Circuitry is provided for controlling the amplitude and phase of the information read from the information store to compensate for any variations in the speed of the information store.
