Title: Production of thin film magnetic head
Inventor: HASHIMOTO TADASHI
IPC: G11B5/31
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic head suitable for high recording density without decreasing the reluctance of an upper pole by forming the upper pole having an eaves part starting from a gap depth end and receding gradually from a lower pole in the direction straddling a magnetic coil. SOLUTION: An insulation layer 2 is formed on a lower pole 1 such that the tapered forward end thereof corresponds to a gap depth end 5e being formed in the future on the lower pole 1. The insulation layer 2 is then etched along with a resist 3 so that the shape thereof is transferred to the insulation layer 2 thus tapering the insulation layer 2. When an upper pole 4 is formed on a tapered insulating material, the upper pole 4 is machined to have an eaves part 5 receding gradually from the lower pole 1 and a smoothly tapered part can be provided. Since the reluctance can be decreased at gap depth end 5e of the upper pole 4, magnetic saturation can be prevented in the early stage.
