Tapered rolling tape edge guide mechanism and methods

摘要

A mechanism and method for guiding a tape across a transducer, and a method for making the mechanism. The mechanism has one rolling guide on either side of the transducer. Each guide has a tapered surface and a flange at one end of the tapered surface. Each tapered surface biases one edge of the tape against a flange to fix the tape's position in the transverse direction on opposite sides of the transducer. The taper of the first and second guides are oriented in opposite directions.
