Abstract
A magnetic tape recording and/or reproducing apparatus having two electric motors, one of which is a capstan driving motor and the other is a reel driving motor. A tape drive capstan is directly driven by the said capstan driving motor without any belts, and transports magnetic tape at a constant velocity by coaction with a pinch roller during recording or reproducing of the magnetic tape. The apparatus has two tape winding reels, and the magnetic tape is wound up by either of the two tape winding reels according to the direction in which the magnetic tape is required to be transported. Each of the two tape winding reels is respectively rotated through idle wheels by the reel driving motor, which is separate from the two tape winding reels, without any slippage at the tape winding reels during recording or reproducing. The idle wheels can engage with both an output shaft of the reel driving motor and one or the other of the two tape winding reels to transmit the rotation of the output shaft of the reel driving motor to one or the other of the two tape winding reels during recording, reproducing and fast feed in both the forward and backward direction of the magnetic tape.
