Abstract

To obtain the correct tape wrap angle at the head in a cassette loaded recorder, tape guiding support "outriggers" integral with the head assembly are provided. The outriggers are located on either side of the active portion of the head structure to guide the tape and to establish the tape/head wrap angle independent of the exact locations of the cassette guides. Slots separate the active head structure from each of the outriggers, presenting an edge at each side of the head to skive any air film adherent to the moving tape as it approaches the head's transducer. Additionally, the entire head and outrigger structure is fabricated from the same or mechanically similar materials and has an overall constant area profile contour which wears at a uniform rate due to tape abrasion.

Dependent claims

In a recording system including a magnetic transducer assembly, the improvement comprising:

a, means for transporting a recording medium over said magnetic transducer assembly, said assembly having a magnetic transducing element located thereon,
b, means, external to said magnetic transducer assembly, for guiding said recording medium at nominal wrap angles relative to said magnetic transducing element,
c, said magnetic transducer assembly further comprising
an arcuate surface extending in the direction of said medium's motion, and
having two slots therein, said slots dividing said arcuate surface into a first outrigger, a central land for containing said magnetic transducing element at the apex thereon, and a second outrigger, wherein 1, the edges of said slots prevent entrainment of air between said medium and said magnetic transducing element, 2, said outriggers so position said medium as to maintain said nominal wrap angles substantially independent of variations in said means for guiding, and 3, said arcuate surface being so shaped that said recording medium continues to exert a constant pressure across said surface as said surface wears, whereby said surface maintains a constant area profile.
