Abstract:
1. A rotatable tape guide configured for rotation about a central axis, said tape guide comprising: a cylindrical barrel having a cylindrical peripheral surface parallel to said central axis; and guide flanges substantially at each outer side of said cylindrical barrel and having a frusto-conical surface, said frusto-conical surface configured at a taper angle outward with respect to the perpendicular direction from said cylindrical surface; said taper angle of said guide flange substantially at an angle such that the angle at which a tapered tangential line extends from the circumference of said cylindrical peripheral surface of said cylindrical barrel and along the taper of said guide flange, to the maximum periphery of said frusto-conical surface, is at the maximum potential angle of attack from a magnetic tape at a supply reel with respect to said guide flange.
