Abstract: A method for manufacturing magnetic recording tape includes applying a front coat including a magnetic component to a substrate to provide a coated substrate. The coated substrate defines a first face and an opposing, second face, the first face extending between a first corner and an opposing, second corner, and the second face extending between a third corner and an opposing, fourth corner. An abrasive surface is moved against the first corner of the coated substrate to abrasively remove a volume of material from the first corner. In particular, the abrasive surface is angularly offset at a substantially non-orthogonal angle from the first face of the coated substrate.

Abstract: Sheet material suitable for preparing visual transparencies comprising:(a) a backing that is transparent to visible light,(b) an image receptive layer transparent to visible light adhered to at least one major surface of said backing, and(c) an anti-blocking layer transparent to visible light adhered to at least one major surface of said backing.The sheet material has an opague border extending around the periphery thereof. The sheet material also has an area of increased caliper along one edge thereof; this area extends inward from the edge for a distance not exceeding the width of the opague border along the edge. The border provides the sheet material with a frame, while the area of increased caliper provides improved feeding reliability for xerographic imaging apparatus.
