PROBLEM TO BE SOLVED: To provide a magnetic head, a magnetic disk device having the same and a reproduction method using the magnetic head capable of improving the quality of reproduction signal.SOLUTION: The magnetic head includes: a first magnetic material layer 56a having a fixed magnetization direction; plural reproduction elements 54a, 54b, 54c and 54d, which are disposed faced to the first magnetic material layer being interposed by an insulator layer 55; and a second magnetic material layer 56b the magnetization direction of which is not fixed. At least two of the plural reproduction elements are disposed so that each of the first magnetic material layer and the second magnetic material layer cross any straight line, and the magnetization of the first magnetic material layer is fixed to be oriented in a direction different from each other.SELECTED DRAWING: Figure 3 |
