摘要： A disk drive having a layer of lubricant on a disk surface, where an undesirable lubricant layer thickness modulation is reduced by varying ω/f during operation of the disk drive. Here ω is the angular velocity of the disk and f is a resonant frequency of a head assembly containing the head. In this manner, the amplitude of the lubricant thickness modulation is decreased, improving disk drive performance. The ratio ω/f is preferably varied by varying the disk angular velocity ω.

摘要： An air bearing burnish slider burnishes very small asperities and cleans the loose particles that adhere to the magnetic recording media. The slider applies a controllable contact force to effectively burnish disk asperities or partially attached particles. In addition, the slider cleans the loose particles effectively while flying in a stable fashion. In a low pitch design, diagonal rails push particles away from the disk surface and trailing edge pads contact the disk at lower linear velocities. Rail pads retain loose contamination and debris in their pockets and burnish asperities. Another design provides a milder burnish force and flies in a high pitch configuration. The trailing edge pads provide stable contacts and the rails help in sweeping away debris. In both designs, the contact forces can be controlled by adjusting linear velocities. A step taper at the leading edge provides a pitch-producing lift force.
摘要翻译：空气轴承抛光滑块抛光非常小的凹凸，并清洁附着在磁记录介质上的松散颗粒。滑块应用可控的接触力来有效地抛光磁盘粗糙度或部分附着的颗粒。此外，滑块可以以稳定的方式有效地清洁松散的颗粒。在低间距设计中，斜轨将颗粒推离盘表面，后缘垫以较低的线速度接触盘。轨道垫在其口袋中保持松散的污染和碎屑，并且消除粗糙。另一种设计提供更温和的抛光力并以高间距配置飞行。后缘垫提供稳定的触点，导轨有助于扫除碎屑。在这两种设计中，接触力可以通过调整线性速度来控制。在前缘的阶梯锥形提供产生俯仰的提升力。

摘要： A Hard Disk Drive (HDD) includes a write-inhibit signal that is generated by a head-disk interaction sensor during a write process that is integrated with a suspension of the HDD when fly-height modulation of the slider is detected during a write process. The suspension load beam includes a dimple and a laminated flexure. The laminated flexure includes a surface that is adapted to receive a slider and a surface that is adapted to contact the dimple. The head-disk interaction sensor is fabricated as part of the laminations of the flexure. The head-disk interaction sensor can be an accelerometer that senses an acceleration of the flexure when the slider contacts the disk of the disk drive and/or a pressure sensor that senses a pressure between the flexure and the dimple when the slider contacts the disk. A write-inhibit circuit is responsive to the sensor signal by inhibiting the write process.
