ABSTRACT OF THE DISCLOSURE Apparatus for reproducing digital signals recorded on a recording tape comprises a rotary drum about which a recording tape can be trained, a rotary head mounted in the drum, a transport mechanism for transporting the tape over the drum and rotating the head so that a relative speed is established between the head and the tape and the head scans the tape and generates reproduced digital signals in re- sponse to digital signals recorded on the tape, and a mode-control mechanism for controlling the transport mecha- nism so that the tape is transported over the drum at an absolute tape speed that can be varied. A servomechanism responsive to variations in the absolute tape speed adjusts the transport mechanism so that the head acquires a rotary speed such that the relative speed is restored to and maintained at a substantially constant value, not withstand- ing changes in the absolute tape speed effected under the control of the mode-control mechanism. -1-
