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.

Tape drive control apparatus

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.
