    • A magnetic disk drive comprises a recording medium, a slider, and an alignment device for aligning the slider with respect to the medium. No film made of liquid lubricant is disposed on the surface of the medium. The slider incorporates: a slider main body including a thin-film magnetic head element disposed near a medium facing surface; and a protection film made of a tetrahedral amorphous carbon film for protecting the medium facing surface. The alignment device makes the slider retreat from the surface of the medium when the medium is stopped, and makes the slider face toward the surface of the medium when the medium is rotated. The magnetic disk drive further comprises a distance control device for controlling the distance between the medium and the thin-film magnetic head element.

    • A thin film magnetic head includes a medium projection detection mechanism that detects a projection on the surface of a recording medium. The medium projection detection mechanism has a discharging electrode, a capacitor, and an input line and an output line that are connected to the discharging electrode. The discharging electrode is configured to receive a voltage applied through the input line, and the capacitor is configured to store electric charge by the applied voltage. The output line is connected to a projection detection processing system and is connected to the charging electrode and the projection detection processing system to detect the location of the projection that is a detection target by detecting voltage change that is caused by discharging between the discharging electrode and the projection when the projection is detected.

    • The invention provides a thin-film magnetic head having a magneto-resistive effect device of the CPP (current perpendicular to plane) structure comprising a multilayer film in which a fixed magnetization layer, a nonmagnetic layer and a free layer are stacked together in order. The fixed magnetization layer, nonmagnetic layer and free layer extend away from an air bearing surface that is a plane in opposition to a medium, the length of the fixed magnetization layer in a depth direction normal to said air bearing surface is greater than the length of the free layer in the depth direction. A shunt layer for shunting the sense current is located at a farther distance in the depth direction than the free layer, and the shunt layer is separated from the free layer by a constant gap in the depth direction.

    • The invention provides a thin-film magnetic head having a magneto-resistive effect device of the CPP (current perpendicular to plane) structure comprising a multilayer film in which a fixed magnetization layer, a nonmagnetic layer and a free layer are stacked together in order. The fixed magnetization layer, nonmagnetic layer and free layer extend rearward from an air bearing surface that is a plane in opposition to a medium, the length of the depth-wise side of the fixed magnetization layer is longer than that of the free layer, and a shunt layer for shunting a sense current is formed more on the depth-wise side of, and kept constantly away from, the free layer. There are thus much more favorable advantages obtained: even when device size is further reduced and narrowed, degradation of frequency characteristics is hold back, any increase in the thermal magnetic noise is stayed off, and performance fluctuations are minimized.
    • 本发明提供一种具有CPP(电流垂直于平面)结构的磁阻效应器件的薄膜磁头,其包括多层膜,其中固定磁化层,非磁性层和自由层按顺序堆叠在一起。 固定磁化层,非磁性层和自由层从作为与介质相反的平面的空气轴承表面向后延伸,固定磁化层的深度方向的长度比自由层的长度长, 用于分流感测电流的并联层更多地形成在自由层的深度方面并且保持不断地远离自由层。 因此,获得了更多有利的优点:即使当器件尺寸进一步减小和变窄时,频率特性的劣化被阻止,热磁噪声的任何增加都将被停止,并且性能波动最小化。
