摘要： When a piezoelectric element is deformed in the direction of decreasing a flying height, a pressure at a trailing pad increases, and the flying height of a magnetic head is not efficiently decreased and may be increased conversely in some occasions.A position of contact between a suspension and a dimple is set toward a leading edge with respect to a piezoelectric element, and a pad for generating a positive pressure is disposed between the dimple and the piezoelectric element in addition to a trailing pad. Fluctuations of a positive pressure generated toward the leading edge with respect to the dimple are thus suppressed when the piezoelectric element is deformed.
摘要翻译：当压电元件在降低飞行高度的方向上变形时，拖尾垫片处的压力增加，并且磁头的飞行高度不能有效降低，并且在某些情况下可能增加。将悬架和凹坑之间的接触位置设定为相对于压电元件的前缘，并且除了拖尾垫之外，还在凹坑和压电元件之间设置用于产生正压的焊盘。因此，当压电元件变形时，因此抑制了相对于凹坑向前缘产生的正压的波动。

摘要： Provided is a magnetic head slider apparatus that can minimize a change in a roll angle caused by an impact force even with a submount mounted on a side surface thereof and achieve steady flying with the roll angle minimized. A dimple position and a pressure center position of a lifting force are moved in a slider width direction to thereby align a center of mass of a slider having a submount including a laser diode mounted on a side surface thereof, the dimple position, and the pressure center position of the lifting force with each other. This provides a magnetic head slider and a suspension thereof, and a magnetic disk drive apparatus offering higher recording density and higher reliability.

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 head element is made into contact with the surface of a recording medium so as to realize a float-up degree of 5 nm. Accordingly, a slider incorporating the head element for recording and reproducing data to and from the recording medium is provided thereon with a plurality of pads having step parts, and one of the plurality of pads, on which the head element is mounted, has a height which is less than that of the other pads. Thus, the pads other than the pad on which the head element is mounted are floated up while the pad on which the head element is mounted is stably made into contact with the surface of the recoding medium by means of a meniscus suction force and a damping action of lubricant applied on the surface of the recording medium.
