Claim Text:
1. A magnetic tape having an entire thickness of from 2 μm to 8 μm produced by cutting a magnetic sheet with a wide breadth into a tape with a predetermined width using a cutting device, wherein the magnetic sheet comprises a magnetic layer with a thickness of 10 to 300 nm containing magnetic powder and a binder formed on one surface of a non-magnetic substrate, and a primer layer comprising inorganic powder and a binder having a thickness of 0.1 μm to 3.0 μm between said magnetic layer and said non-magnetic substrate, and wherein a center line average height (Ra) along a roughness curve of a cut edge of the magnetic tape in a thickness direction is from 0.09 to 0.23 μm.
