ABSTRACT:
A tape guide, especially a tape guide of large surface area for high-speed tape transport apparatus, having at least on the tape guide surface a mixture of plastics material and lubricant exhibiting a specific surface roughness and a specific coefficient of friction, the said mixture consisting of 10 to 70 percent by weight of lubricant, e.g. natural graphite, molybdenum disulfide and/or tungsten disulfide, and 90 to 30 percent by weight of plastics material, e.g. polyoxymethylene, polyethylene and polypropylene. The plastic/lubricant mixture may also be in the form of a strip-like element fastened to a backing member. The tape guide can be used for any type of tape transport apparatus, especially in video recording equipment employing magnetic tape on which the signals are recorded in longitudinal tracks.
