ABSTRACT:
A cleaning system for magnetic tape intended for high density magnetic data usage combines passing a high volume flow of negatively ionized air across a moving tape surface with simultaneous wiping of one surface of the tape with a soft, non-abrading material to remove dust and foreign particles from the tape. The air flow passes through a filter, which removes the particles. The air then passes through an ionizing grid and back across the tape in a continuous, closed loop operation. The cleaning material is housed in a removable cartridge along with the air filter. A brush moves in response to loading of the tape to pinch the tape and thus remove particles from the surface opposite the tape surface engaged by the soft material.
