| 摘要 |
An object of the present invention is, in a magnetoresistive head having a magnetoresistive film that exhibits a change of resistance according to a direction of magnetization wherein information is reproduced from a magnetic recording medium by detecting the change of resistance of the magnetoresistive film, and an information reproduction apparatus that reproduces information from the magnetic recording medium by detecting the change of resistance of the magnetoresistive film, to provide a magnetoresistive head with heat generation being suppressed even if a current density of a sense current through a magnetoresistive film is high, and an information reproduction apparatus provided with such a magnetoresistive head. A height of a center portion of the magnetoresistive film is shorter than a height of end portions thereof, or a width of the end portion of the magnetoresistive film varies with height.
