MAGNETIC TAPE CLEANING AND TENSIONING APPARATUS Abstract of the Disclosure A magnetic tape cleaning and tensioning apparatus is disclosed which performs the dual functions of cleaning magnetic tape and tensioning the tape, thereby providing a portion of tape free of debris and in tension at the reading and writing location. The magnetic tape is formed in a loop and is contained in a tape cartridge. Rollers are provided in the cartridge for separating portions of the magnetic tape so that adjacent surfaces of the tape do not contact each other. A tape cleaning and tensioning pad holder, having attached thereto a tape cleaning and tension- ing pad, is contoured for providing an area of engagement of the pad and magnetic tape as the tape passes over one of the rollers contained in the cartridge. The cleaning and tensioning pad cleans debris, such as dust and loose oxide particles, from the tape and adds drag to the tape as it passes over this roller. A pressure roller and capstan engage the tape downstream from this roller such that the magnetic tape is in substantial tension be- tween this roller and the capstan and pressure roller. As the tape moves downstream from the capstan and pressure roller, it is substantially loose until it again engages the cleaning and tensioning pad.
