US 4,238,088 A · Guide for a thin tape-like recording medium, particularly a magnetic tape

Abstract

A tape guide, especially a guide for thin magnetic tapes which are subjected to strong acceleration forces in the longitudinal direction, and a tape transport apparatus with a central capstan, comprising such a tape guide. The tape guide includes one or two rotatable, but fixedly arranged guide rollers having flanges arranged around part of the periphery thereof, which flanges each have an ingress and an egress chamfer for the tape. When one guide roller is used, the magnetic head is positioned between a tape reel and the guide roller and, when two guide rollers are used, it is positioned between the said two rollers, the magnetic head bearing against the unsupported span of tape in each case. The tape guide may be provided with means for producing cushions of air for stabilizing the roller as it rotates.

Dependent claims

A guide arrangement for a thin tape-like recording medium, especially a magnetic tape which, when transported past a magnetic head, is subjected to strong acceleration forces in the longitudinal direction, said arrangement comprising:

at least one guide roller mounted for rotation about a relatively stationary axis, and
two relatively stationary, arc-shaped guide surfaces, each facing said guide roller on one side thereof, extending around part of the periphery of the guide roller and having an ingress and an egress chamfer for the tape,
whereby entrapment of air between the tape and the guide roller is substantially reduced and gradual entry of the tape into the zone of effective lateral guidance of the tape is insured.
