Claims

[Scope of Claim for Utility Model Registration] (1) A magnetic tape loading type magnetic recording and reproducing device that performs recording and reproduction by winding a magnetic tape pulled out from a supply reel around a rotating drum equipped with a magnetic head; , a reciprocally rotating disk equipped with a pair of guide pins and an inclined pin for loading the magnetic tape onto the outer periphery of a rotating drum, and a tape control arm using this disk as a drive source to pull out the magnetic tape from the supply reel. A magnetic recording/reproducing device comprising a drive device that always applies a constant back tension to a magnetic tape. (2) The magnetic recording and reproducing device according to claim 1, wherein a tooth row is formed on the outer periphery of a disk. (3) The drive device includes a drive gear rotated by the tooth row of the disk, a friction clutch that transmits the pull-out torque of the magnetic tape from the drive gear to the tape control arm, and a friction clutch that controls the rotation angle of the tape control arm. The magnetic recording and reproducing apparatus according to claim 1, which comprises a brake belt that applies a predetermined brake to the supply reel in response. (4) The magnetic recording and reproducing apparatus according to claim 1, wherein the tape control arm is provided with a tension spring that biases the magnetic tape in a direction to draw out the magnetic tape from the supply reel.
