Abstract

A pinch roller type tape drive for driving a magnetic tape on a VTR or the like comprises a capstan for driving the magnetic tape, and a pinch roller for pressing the magnetic tape against the circumference of the capstan so that the magnetic tape may not slip relative to the circumference of the capstan. The outermost layer of the pinch roller is formed of an elastic material having a hardness higher than that of rubber, which is used for forming the outermost layer of a conventional pinch roller. The pinch roller is capable of pressing the magnetic tape against the circumference of the capstan at a sufficient pressure without contacting the circumference of the capstan.
