ABSTRACT:
A tape guide system wherein a magnetic tape having different resistivites on its back and front travels in contact with guide elements, the members of these elements which are in contact with the tape being matched to the relevant face of the tape in respect of surface resistivity and/or of charge affinity. The members contacting the front of the magnetic tape accordingly consist of a conductive or low-insulation material and the members contacting the back of the tape consist of a high-insulation material. In alternative embodiments, the contact members can consist of a material of low conductivity, or of a plastic with an added conductive material. The novel guide system can be used in any type of high-speed magnetic tape transport mechanism. The invention also concerns the tape guide elements per se, and magnetic tape cassettes employing the tape guide system.
