Abstract

PURPOSE:To achieve excellent picture, by locating a vapor-deposited tape so that a sharp angle between an easy magnetization axis of a head trailing edge and a head magnetic field can be greater than that of a head leading edge and the field. CONSTITUTION:Vapor-deposition with a slope is carried out on a base film 1 being a base, by irradiating electron beam 9 on a ferromagnetic metal 8 such as Co or Co alloy. When a vapor-deposited tape 22 with a slope consisting of a base film 22a and a ferromagnetic substance layer 22b moves toward the arrow 20, an edge 19 is a leading edge and an edge 18 is a trailing edge. An angle between a gap 21 to the tape 22 having a magnetization easy direction 16 and a head magnetic field Hh17 of the trailing edge is theta3, when the tape 22 moves toward the arrow 20 and an angle to the leading edge is theta4. The head is located so that the tape 22 proceeds to the direction of the arrow 20 as theta3>theta4, allowing to obtain excellent reproduced picture.
