Title:
薄膜磁気ヘッドの製造方法
Document Type and Number:
Japanese Patent JP3986292
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enhance the magnetic field in the direction perpendicular to the surface of a recording medium, generated from a magnetic pole part, and to shorten the magnetic path length to enhance high frequency characteristics in a thin film magnetic head. SOLUTION: A thin film magnetic head is provided with a first and a second magnetic layers 8 and 14, a gap layer 9 provided between the first and the second magnetic layers 8 and 14, a connecting part 12 magnetically connecting the first and the second magnetic layers 8 and 14 to each other at a position apart from a medium facing surface ABS and a thin film coil 10, apart of which is provided between the first and the second magnetic layers 8 and 14. The second magnetic layer 14 has a magnetic pole part layer 14A and a yoke part layer 14B. The saturated magnetic flux density of the magnetic pole part layer 14A is higher than the saturated magnetic flux density of the yoke part layer 14B. The yoke part layer 14B magnetically connects the upper end part of the connecting part 12 with the rear end surface of the magnetic pole part layer 14A.
