摘要： An apparatus for reproducing digital signals recorded on a magnetic or other recording tape includes a servo mechanism which is effective, when the tape is transported at a high speed in either a fast-forward or rewind mode, to maintain a relative speed between the tape and a rotary head that is substantially the same as that in the normal playback mode. Moreover, in the rewind mode, the rotary head is rotated in the direction opposite to that in the normal playback mode, while the absolute value of the relative speed remains the same as that in the normal playback mode. Further, the digital signals reproduced by the rotary head in the rewind mode have their sequential order reversed.

摘要： 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 response to digital signals recorded on the tape, and a mode-control mechanism for controlling the transport mechanism 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 withstanding changes in the absolute tape speed effected under the control of the mode-control mechanism.
