    摘要: A tape drive control apparatus in which a tape is wound on a capstan rotating at a constant speed and driven by the friction between the capstan and the tape without using a pinch roller. The tape is moved apart from the capstan upon the fast mode such as the fast forward or rewinding mode and upon the stop mode.

    摘要: A tape driving apparatus in which even if the radius of a magnetic medium such as a magnetic tape wound on a supply and/or take-up reel is varied, a current flowing in a servo motor coupled directly to a capstan, which is varied in accordance with a load, is utilized to make the speed of the servo-motor constant by controlling a reel motor and hence to make the back tension and take-up tension of the magnetic tape equal.
