发明名称 Thin film magnetic head including helical coil
摘要 A magnetic coil of a thin film magnetic head includes uniform upper (71) and lower (72) coil pattern pieces extending in the direction parallel to the medium-opposed surface at a constant width. A magnetic pole has the front end exposed at the medium-opposed surface. The magnetic pole extends backward from the front end. The length of the uniform lower (71) and upper (72) coil pattern pieces correspond to the width of the magnetic pole. The thin film magnetic head enables establishment of the narrowest width at the uniform upper and lower coil pattern pieces in the magnetic coil. The length of the magnetic pole is reduced as much as possible. The uniform upper and lower coil pattern pieces are also allowed to have a minimum length. The electric resistance is thus reduced in the magnetic coil. This results in establishment of an effective magnetic property in the thin film magnetic head.
