ABSTRACT:
A tape drive control apparatus controls to set a tape speed to be constant in a fast forward or rewind mode (wherein a magnetic tape is driven by only reel motors without using a capstan) by using an output from rotation detectors for respectively detecting rotational frequencies of the supply and take-up reels, and to set a tape tension to be constant in a constant-speed mode (wherein the magnetic tape is driven by the capstan) by utilizing part of a tape velocity control system irrespective of the rotational frequency of the capstan.
