Abstract

PURPOSE:To simplify a manufacture process and to improve cross-talk, by forming a magnetic material layer for shielding between tracks of an upper magnetic material layer and magnetically connecting it to a lower common magnetic material layer. CONSTITUTION:On a substrate 5, a lower common magnetic material layer 2 is formed uniformly, and an insulator layer 7, conductor layers 4a and 4b, an insulator layer 6, and upper magnetic material layers 1a-1c which have tracks with track width are formed in prescribed shapes. Between tracks of the upper magnetic material layers 1a-1c of a multielement thin-film magnetic head, magnetic material layers 9a and 9b for shielding are formed in prescribed shapes and connected magnetically to the lower common magnetic material layer 2. The magnetic material layers 9a and 9b are formed in the same process with, for example, the upper magnetic material layers 1a-1c.
