Abstract: A magnetic head is described for use in a disk drive having a disk (30) that is rotated during operation of the disk drive and stationary when the disk drive is non-operational. The disk (30) includes a surface containing data tracks. The magnetic head comprises a slider (10) including a forward edge (13) and an air bearing surface. A read/write transducer (15) is mounted at the trailing edge (14) of the slider (10). The slider (10) and transducer (15) are mounted within the disk drive, relative to the surface of the rotating disk (30), to fly above the surface of the disk (30), to fly above the surface of the disk (30) during rotation of the disk (30), for reading and writing data from and to the data tracks, and to come to rest on the surface of the disk during non-operation of the disk drive. An array of overcoat protrusions (20) is formed on and spaced across the slider to cover a predetermined and discrete area of the slider (10) in a manner so that when the slider (10) and transducer (15) come to rest on the surface of the disk (30), contact with the surface of the disk occurs only at the array of overcoat protrusions (20).

Abstract: Method and apparatus are presented for electrically coupling a slider (201) to ground. In one embodiment, a bonding pad (227) is provided on a side of the slider body separate from the bonding pad(s) used for read/write signals. This separate bonding pas is electrically coupled within the slider body to components that are to be coupled to ground. A separate conductor (223) provided on the suspension (e.g., a trace, a flex circuit, etc.) may be electrically coupled to the separate bonding pad via gold ball bonding. The conductor is also coupled to ground in the hard-disk drive device (e.g., via the preamplifier). The use of the separated bonding pad and trace may negate the need to use a conductive adhesive to electrically ground the slider via its attachment to the tongue of a slider.

Abstract translation: 呈现了用于将滑块（201）电耦合到地的方法和装置。 在一个实施例中，在与用于读/写信号的接合焊盘分离的滑块体的一侧上设置焊盘（227）。 这种单独的接合片在滑块体内电耦合到要耦合到地面的部件。 设置在悬架上的单独的导体（223）（例如，迹线，柔性电路等）可以通过金球接合电耦合到单独的接合焊盘。 导体也耦合到硬盘驱动装置中的接地（例如，经由前置放大器）。 使用分离的接合焊盘和迹线可能会使得不需要使用导电粘合剂来将滑块经由其附接件电连接到滑块的舌部。
