Abstract
A tape guide system, especially a tape guide system for a magnetic tape cassette, comprising conductive connecting means between the tape guide elements and/or the front and back of the tape, prevents the tape from blocking, slipping from the tape reels, or folding over. In practical embodiments, pieces of flexible conductive plastics film are arranged in the vicinity of the guide elements. The novel tape guide system can be used in any type of magnetic tape transport mechanism in which increased friction occurs when the tape is transported, especially in video cassettes for all systems.
