IPC: G11B5/39
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head capable of effectively using a magnetic recording medium when a high-frequency signal is processed, and a magnetic head manufacturing method capable of reducing the number of manufacturing steps and increasing yield. SOLUTION: A core having a magnetic gap 11a being non-horizontal to a substrate surface is formed in a step shape on the substrate. Thus, when a high-frequency signal is processed, the signal is recorded in the entire area of a magnetic recording medium, and the magnetic recording medium is effectively used.
