Abstract

See full text

A tape appliance includes first and second tape guide components. The tape path includes a first path portion between a tape supply reel and the first guide component, a second path portion between a tape take-up reel and the second guide component, and a joining path portion between the first and second guide components. When tape travel is in the first longitudinal direction, a first tape head module engages the tape along one of the first or second tape path portions, and a second tape head module engages the tape along the joining path portion, such that the first tape head module is the leading module. When the tape travel is in the reverse direction, the first tape head module is positioned to engage the tape along the other of the first or second tape path portions, such that the first tape head module remains the leading module.
