Method for manufacturing thin-film magnetic head with spin valve magnetoresistive sensor |
摘要 |
A manufacturing method of a thin-film magnetic head with a spin valve effect MR read sensor includes a temperature-annealing step of firmly fixing the direction of the pinned magnetization in the spin valve effect MR sensor. The temperature-annealing step is executed by a plurality of times.
