ABSTRACT:
A recording and read system capable of for recording and reading information (Va) on/from a record carrier (1) with a higher speed than that with which it is received or supplied. In order to compensate for differences between the recording speed and the read speed and between the receiving speed and the supply speed the device includes an input buffer memory (6) and an output buffer memory (11). In order to minimize the required storage capacity of the buffer memories (6, 11), the device comprises a control unit (10) which is loaded with a control program which temporarily interrupts the recording and read process in such a way that the degree of filling of the capacity of the input buffer memory (6) and of the capacity of the output buffer memory (11) remains within specific limits.
