Abstract
A tape guide has a tape supporting surface extending across a major surface of an advancing tape at a supporting region extending from a tape touchdown region to a tape liftoff region. The tape guide stresses the advancing tape with the tape supporting surface uniformly across the tape and at both tape edges. A reference surface extends at an acute angle to the supporting surface between and exclusive of the tape touchdown and liftoff regions in order to position the advancing tape at one of its tape edges.
