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.

A method for manufacturing magnetic recording tape, the method comprising:
- applying a front coat including a magnetic component to a substrate to provide a coated substrate, the coated substrate defining 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;
- and
- moving an abrasive surface against the first corner of the coated substrate to abrasively remove a volume of material from the first corner;
- wherein the abrasive surface is angularly offset at a non-orthogonal angle from the first face of the coated substrate.
A method of forming a length of magnetic recording tape, the method comprising:
- coating a substrate with a coating to provide a coated substrate, the coated substrate being adapted to record and defining a length, a top face, and an opposing, bottom face;
- cutting the coated substrate to form a first edge along the length of coated substrate and a second edge along the length of the coated substrate;
- and
- abrading the first edge with a moving abrasive surface disposed at a non-orthogonal angle to the top face of the coated substrate, including removing a volume of the coating proximate the first edge.
A method for manufacturing magnetic recording tape, the method comprising:
- applying a front coat including a magnetic component to a substrate to provide a coated substrate, the coated substrate defining 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;
- moving a first abrasive surface against the first corner of the coated substrate to abrasively remove a volume of material from the first corner, wherein the first abrasive surface is disposed at a non-orthogonal angle to the first face;
- and
- moving a second abrasive surface against the second corner to abrasively remove a volume of material from the second corner, the first and second abrasive surfaces being separate from one another.
