Abstract

PURPOSE:To achieve a magnetic tape with an axis easy to magnetize toward the broadwise direction and high coercive force, by vapor-depositing a magnetic material at the same time from evaporation sources provided symmetrically at the oblique bottom toward the broadwise on a running base film. CONSTITUTION:Magnetic metals 4 and 4' are simultaneously vapor-deposited on a running base film 2 from two crucibles 3 and 3' located symmetrically at the bottom left and right in the broadwise direction of a roller 1. Thus, a magnetic tape having an easy magnetization axis toward the broadwise direction and high coercive force can be obtained.
