置。 A rotating magnetic head device, a loading means for pulling out a magnetic tape wound on a pair of reels from one reel and winding it around the outer peripheral surface of a drum of the rotating magnetic head device, and a loading motor for driving the loading means. , a magnetic recording and reproducing device comprising a reel motor for rotationally driving the reel, a braking means for braking the reel, a rotation detecting means for detecting a non-rotating state of the reel, and a detection output from the rotation detecting means. and control means for controlling the driving of the loading motor and the reel motor based on the above-mentioned information, as well as controlling the operation of the braking means, and a non-rotating state of the one reel is detected by the rotation detecting means during the loading operation. After winding a predetermined amount of magnetic tape from the other reel to the one reel in a non-contact state with the drum of the rotating magnetic head device, the other reel is braked and the magnetic tape is wound onto the one reel. A magnetic recording and reproducing apparatus characterized in that a magnetic tape is drawn out by the loading means and wound around the outer peripheral surface of the drum of the rotating magnetic head device.
