摘要： A magnetic head slider mounted on a magnetic disk unit for supporting a magnetic head that writes and reads information to and from a magnetic disk is constructed such that a depth δs1 from the surfaces of leading and trailing pads, which come into contact with a medium surface when the disk is at rest, to stepped surfaces formed on the air inflow side of the leading pads, a depth δs2 from the contact surfaces to stepped surfaces formed on the air inflow side of the trailing pad and a step depth δs3 from the contact surfaces to the surfaces of side rails are in a relation of δs1≦δs2≦δs3. With this arrangement, the slider can follow the waved medium surface at a low flying height with a small flying height fluctuation, thus realizing high density recording, high reliability and reduced cost of the magnetic disk unit.

摘要： A magnetic head slider in which a leading pad is projected in a thicknesswise direction of the slider, in comparison with a trailing pad so as to reduce vibration caused by contact between a flat medium surface of a disc and the slider carrying thereon a magnetic head, to reduce variation in flying height caused by wavy unevenness of the medium surface, and to reduce variation in atmospheric pressure around the slider, thereby it is possible to enhance the recording density and the reliability of the magnetic head slider while reducing the costs thereof. Further, a magnetic disc unit using the above-mentioned magnetic head slider.

摘要： Employed is a structure for moving by a micro-actuator not a read/write element but an air-bearing surface pad. The air-bearing surface pad is arranged nearer to the leading end than the read/write element. This arrangement allows the read/write element portion to have a sufficient size, making it possible to mount the currently used read/write element and associated wiring structure. The individual adjustment of a flying height leads to the increased recording density. Moving the read/write element away from the disk during loading/unloading operations can enhance reliability.
摘要翻译：使用的是由微执行器而不是读/写元件而是空气轴承表面垫移动的结构。空气轴承表面焊盘布置成比读/写元件更靠前端。这种布置允许读/写元件部分具有足够的尺寸，使得可以安装当前使用的读/写元件和相关的布线结构。飞行高度的单独调整导致增加的记录密度。在加载/卸载操作过程中将读/写元件远离磁盘移动可以提高可靠性。
