Abstract: The present invention is embodied in an air bearing slider (10). The slider contains a magnetic head (20) for writing and reading data to and from the magnetic medium of a hard disk. The slider is attached to an actuator arm which reciprocates over the disk surface to position the slider over the surface of the disk. When placed in the airflow existing just above the surface of a rotating disk the slider flies above the disk. The slider which has a leading edge (32), a trailing edge (34) and two sides defined between the leading and trailing edges comprises a pair of leading pads (40) positioned near the leading edge, a channel defined between the leading pads, a side pad positioned adjacent to each of the sides respectively, a center pad positioned near the trailing edge and a cavity disposed between the pads. With the side pads being separate from the leading pads as well as the inclusion of the channel providing a reduction in stiction. Further, the present invention's configuration of elements provides a slider with a nearly constant flying height over the entire disk surface, even during changes in airflow velocity, skew angles and loading. Also, the slider possess high pitch and roll stiffness, which contributes to its ability to maintain a near constant flying height.

Abstract translation: 本发明体现在空气轴承滑块（10）中。 滑块包含用于向硬盘的磁介质写入数据和从硬盘的磁介质读取数据的磁头（20）。 滑块连接到在磁盘表面上往复移动的致动器臂上，以将滑块定位在磁盘表面上。 当放置在旋转盘表面上方的气流中时，滑动器在盘上方飞行。 具有前缘（32），后缘（34）和限定在前缘和后缘之间的两侧的滑块包括位于前缘附近的一对前垫（40），限定在前垫之间的通道， 分别邻近每一侧定位的侧垫，定位在后缘附近的中央垫和置于垫之间的空腔。 使侧垫与前垫分开以及包含通道，从而减少静摩擦。 此外，即使在气流速度，倾斜角度和负载的变化期间，本发明的元件配置也提供了在整个磁盘表面上具有几乎恒定浮动高度的滑块。 此外，该滑块具有高节距和侧倾刚度，这有助于保持接近恒定的飞行高度。
