ABSTRACT:
A magnetic recording and reproducing apparatus is arranged to be loaded with a supply reel and a take-up reel with a magnetic tape wound around them, to move the tape from the supply reel to the take-up reel by driving and rotating forward the two reels and a capstan with the tape pushed into contact with the capstan and to rewind the tape moving it from the take-up reel back to the supply reel by driving and rotating these reels and the capstan backward. The apparatus is provided with means for detecting the rotating speed of the supply reel in rewinding the tape; and control means for controlling and changing the rotation speed of the capstan according to the detected rotating speed of the supply reel during the process of rewinding the tape.
