    • A magnetic disk drive includes a magnetic recording medium and a magnetic head slider adapted to fly over a surface of a magnetic recording medium and read or write information. The magnetic head slider includes a slider air bearing surface and a magnetic transducer. The slider air bearing surface includes a front pad having front rail surfaces and front step bearing surfaces, a rear pad having a rear rail surface and a rear step bearing surface, and a negative-pressure groove interposed between the front pad and the rear pad. A vibration suppressing groove is formed in the rear rail surface so as to be deeper than the rear rail surface and to be closed at its periphery. The vibration suppressing groove quickly damps out translational and pitching vibrations in the flying height direction of the magnetic head slider while stabilizing its flying.
    • 磁盘驱动器包括磁记录介质和适于在磁记录介质的表面上飞越并读取或写入信息的磁头滑块。 磁头滑块包括滑块空气支承表面和磁换能器。 滑块空气轴承表面包括具有前导轨表面和前阶梯支承表面的前垫,具有后轨表面和后台阶支承表面的后垫,以及插入在前垫和后垫之间的负压槽。 在后轨面上形成振动抑制槽,使其比后轨面更深,并在其周边封闭。 振动抑制槽在稳定其飞行的同时快速地减小磁头滑块的飞行高度方向上的平移和俯仰振动。

    • In a magnetic disk drive, translational and pitching vibrations in the flying height direction of a magnetic head slider are to be damped quickly while stabilizing the flying of the magnetic head slider. In one embodiment of the present invention, a magnetic disk drive is provided with a magnetic recording medium and a magnetic head slider adapted to fly over a surface of the magnetic recording medium and read or write information. The magnetic head slider includes a slider air bearing surface and a magnetic transducer. The slider air bearing surface includes a front pad having front rail surfaces and front step bearing surfaces, a rear pad having a rear rail surface and a rear step bearing surface, and a negative-pressure groove interposed between the front pad and the rear pad. A vibration suppressing groove is formed in the rear rail surface so as to be deeper than the rear rail surface and to be closed at its surround.
    • 在磁盘驱动器中,磁头滑动器的飞行高度方向上的平移和俯仰振动将被快速衰减,同时稳定磁头滑块的飞行。 在本发明的一个实施例中,磁盘驱动器设置有磁记录介质和适于在磁记录介质的表面上飞越并读取或写入信息的磁头滑块。 磁头滑块包括滑块空气支承表面和磁换能器。 滑动器空气轴承表面包括具有前导轨表面和前阶梯支承表面的前垫,具有后轨表面和后台阶支承表面的后垫,以及插入在前垫和后垫之间的负压槽。 在后导轨面上形成振动抑制槽,使其比后导轨面更深,并且在其周围封闭。
