る磁気記録再生装置。 A rotating cylinder having a magnetic head, a fixed cylinder supporting rotation of the rotating cylinder, and a guide post for winding a magnetic tape around the outer periphery of the rotating cylinder and the fixed cylinder to determine a winding angle, A first guide post near the cylinder entry side where the magnetic head starts contacting the magnetic tape due to rotation of the rotary cylinder.
The guide post is set so that the overlap angle from the effective winding angle at which the magnetic head records and reproduces signals is larger than the overlap angle at the second guide post near the cylinder exit side, and the overlap angle is set within the range of the effective winding angle. A magnetic recording/reproducing apparatus characterized in that the magnetic tape is arranged so that a flying height of the magnetic tape from the rotating cylinder is equal to or less than the amount of protrusion of the magnetic head from the rotating cylinder.
