MAGNETIC DETECTION ELEMENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To inhibit etching damage in a nonmagnetic intermediate layer in a step of forming a reproducing head. SOLUTION: In one embodiment, the reproducing head 11 has two junction insulation films 16 and 17 between a side edge of a magnetoresistive sensor 112 and a hard bias film 115 on both right and left sides of a track breadthwise direction of the magnetoresistive sensor 112. The reproducing head 11 further has the first junction insulation film 16 in addition to the second junction insulation film 17. The first junction insulation film 16 inhibits the etching damage in the nonmagnetic intermediate layer 214 during the step of forming the reproducing head 11. COPYRIGHT: (C)2008,JPO&INPIT
