。[Claims for Utility Model Registration] In a magnetic recording and reproducing device in which a magnetic tape is spirally wound around a cylinder on which a rotating head is mounted, and the rotating head scans the magnetic tape in a spiral, a rotation detection sensor is provided on a reel stand. It is possible to input and calculate the output from the sensor equipped with the above-mentioned sensor, and to determine abnormalities in tape running based on changes in the number of rotations.A gear integrated into the cylinder is also provided, and abnormalities can be determined by the above-mentioned method. 1. A tape protection device for a DAT, characterized in that a clutch is provided which is operated by a plunger that operates only when the clutch is engaged with the gear and stops the cylinder when an abnormality occurs.
