摘要： Provided is a slide device which can reduce a frictional force more than a conventional slide device when used in an aqueous liquid containing a blood component. In a slide device which includes: a fixed-side slide member having a slide surface; and a rotary-side slide member having a slide surface, the slide device being used in an aqueous liquid containing a blood component in a state where the slide surface of the fixed-side slide member and the slide surface of the rotary-side slide member face each other in an opposed manner, at least one of the fixed-side slide member and the rotary-side slide member is formed of a member which is made of a material which contains silicon and has hydrate of silicon oxide on the slide surface thereof.

摘要： There is provided a head slider for reducing a sticking force or stiction between the head slider and a disk in a disk drive unit in which a difference in level between an air bearing and a head portion is small when the disk rotates in a reverse direction. Air bearing portions having flat top surfaces are formed in parallel with each other on both sides of a side of a slider which flies above the disk at an air outflow end of the slider. A head portion comprising head elements and a protection film for protecting the head elements is provided at an air outflow end of one of the air bearing portions, while a dummy head portion comprising only a protection film is provided at an air outflow end of the other air bearing portion. Top surfaces of the head portion and the dummy head portion are formed lower by a step than top surfaces of the air bearing portions. The top surfaces of the head portion and the dummy head portion on the air outflow ends are formed lower than the top surfaces thereof adjacent to the air bearing portions, whereby the contact resistance between the head slider and the disk resulting when the disk rotates in the reverse direction is reduced.

摘要翻译： 提供了一种磁头滑动器，用于减小磁盘滑动器与磁盘驱动单元中的磁盘之间的粘着力或粘性，其中当磁盘沿相反方向旋转时，空气轴承和磁头部分之间的电平差异小。 具有平坦顶表面的空气轴承部分在滑块的一侧的两侧上彼此平行地形成，该滑块在滑块的空气流出端处在盘上方飞行。 在其中一个空气轴承部分的空气流出端处设置包括头部元件和用于保护头部元件的保护膜的头部，而在另一个空气流出端处设置仅包括保护膜的伪头部 空气轴承部分。 头部和假头部的上表面比空气轴承部的上表面形成为下方。 空气流出端部的头部和虚设头部的顶面形成为比邻近空气轴承部的上表面低，由此当盘旋转时产生的磁头滑块和磁盘之间的接触电阻 反方向减少。

摘要： An MR head includes a slider, and a film structure part which is located on an air outflow side of the slider and includes an MR element for reproducing. The film structure part has an end surface located on an identical side as a floating surface of the slider. The end surface of the film structure part and the floating surface of the slider form a step-like recess which has a depth making it possible to prevent a fine projection on a magnetic disk from hitting the end surface of the film structure part.
