Magnetic recording tape edge processing

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.
