Abstract
When a magnetic tape material is slit into a plurality of magnetic tapes, projections are formed in edge portions of side surfaces of the magnetic tapes. The projections are removed by pressing cutting tools against the edge portions of the side surfaces of the magnetic tape while transporting the magnetic tape. Thus, product quality of the magnetic tape is improved.
