claim

　　１０．前記ＭＲ素子は、外部磁界に応じて磁化方向が変化するフリー層と、前記第１のシールド層と前記フリー層との間に設けられて該第１のシールド層と該フリー層とを交換結合させる磁気結合層と、を有している、請求項９に記載の磁気ヘッド。

10. The magnetic head according to claim 9, wherein
the MR element includes
a free layer of which a magnetization direction changes according to the external magnetic field, and
a magnetic coupling layer that is disposed between the first shield layer and the free layer and that exchange-couples the first shield layer with the free layer.
