PROBLEM TO BE SOLVED: To provide a differential type reproduction head which realizes high resolution and high precision in forming a track width. SOLUTION: In a first magneto-resistive effect element 200, a first fixed layer 230, a first intermediate layer 220 and a first free layer 210 are laminated in this order from a substrate side. In a second magneto-resistive effect element 300, a second fixed layer 330, a second intermediate layer 320, and a second free layer 310 are laminated in this order from the first free layer 210. The second fixed layer 330 and the second intermediate layer 320 substantially play a role as a differential gap. COPYRIGHT: (C)2010,JPO&INPIT |
