摘要： A method and apparatus for controlling lubrication in hard disk drives. Hard disk drives often include lubrication on the disks to protect the disks from incidental contact with the head slider. Embodiments of the invention include lubrication control recesses on the air bearing surface (ABS) of the head slider. The recesses reduce air stagnation on the ABS and/or store excess lubrication that migrates from the disk to the head slider. By reducing build-up of lubrication and storing excess lubrication, the lubrication control recesses avoid failure that may occur as a result of the lubrication interfering with the ABS or the read/write elements of the head.
摘要翻译：一种控制硬盘驱动器润滑的方法和装置。硬盘驱动器通常包括磁盘上的润滑，以防止磁盘与磁头滑块偶然接触。本发明的实施例包括头滑动器的空气轴承表面（ABS）上的润滑控制凹部。这些凹槽减少ABS上的空气滞留和/或存储从盘移动到头滑块的多余的润滑。通过减少润滑的积累和储存多余的润滑，润滑控制凹槽可以避免由于润滑干扰ABS或读/写头元件而导致的故障。

摘要： The surfaces of hard disk drive magnetic media disks are planarized with surface-grafted polymer chains that form a monolayer-thick film of uniform, self-limiting thickness. The thickness is controlled by the molecular weight of the polymer selected. The polymer film may be swollen by a solvent vapor to fill variable width gaps in the topography. The polymer may be cross-linked in place by radiation or thermal processing.

摘要： Nanoimprint lithography using resist material with the addition of a surfactant is described. A template release layer is formed on a pattern of a template. A non-ionic surfactant is added to a resist material to form a mixed resist material. The resist material may comprise a hydrocarbon material having an unsaturated bond, such as an acrylate material. The surfactant may comprise polyalkylene glycol or an organically modified polysiloxane. A resist layer is then formed on a substrate from the mixed resist material. The surfactant added to the resist material forms a resist release layer on the surface of the resist layer. The template is then pressed into the resist layer, where the template release layer and the resist release layer are between the pattern of the template and the resist layer.

摘要： Systems and methods are provided for burnishing a recording head in-situ in a magnetic recording disk drive. The burnishing process generates a tribocurrent, which is electricity generated by the rubbing of dissimilar materials. Different materials exhibit widely different tribocurrent characteristics while in sliding contact. The tribocurrent thus acts as an indicator of the particular materials of the recording head making contact with the magnetic recording media during different stages of the burnishing process. The tribocurrent is thus monitored to determine when it reaches a threshold value. The threshold value indicates that the burnishing has exposed a particular material of the recording head. Thus, the burnishing process may be stopped upon the tribocurrent reaching the threshold value so that the read sensor of the recording head is not burnished and inadvertently damaged.
摘要翻译：提供了用于在磁记录盘驱动器中原位抛光记录头的系统和方法。抛光过程产生摩擦电流，这是通过摩擦不同材料产生的电力。不同的材料在滑动接触时表现出广泛不同的摩擦电流特性。因此，摩擦电流因此用作在抛光过程的不同阶段期间与磁记录介质接触的记录头的特定材料的指示器。因此监测摩擦电流以确定何时达到阈值。阈值表示抛光已经暴露了记录头的特定材料。因此，可以在摩擦电流达到阈值时停止抛光过程，使得记录头的读取传感器不被抛光并且被无意地损坏。

摘要： A micro-electro-mechanical systems (MEMS) type electrostatic microactuator has a fixed electrode and a movable electrode, with the movable electrode being attached to the substrate by a flexure. Each electrode has a plurality of fingers with the fixed electrode fingers and the movable electrode fingers interleaved in a comb-like arrangement. A nonconductive viscous liquid is located between the fingers for damping motion of the movable electrode relative to the fixed electrode. The liquid is held in a reservoir attached to the movable electrode. Capillary pressure pulls the liquid from the reservoir into the small gaps between the interleaved fingers.

摘要： Magnetic disk drives and associated methods are described for an improved process for dissipating liquid droplets that may accumulate on a slider of the magnetic disk drive. For the droplet removal process, the slider having the liquid droplet is unloaded from the magnetic disk. For example, the slider may be unloaded from the magnetic disk and onto a ramp assembly. While unloaded from the magnetic disk, a heating power is applied to a TFC heating element in the slider to increase the temperature of the slider. The temperature is increased to a threshold temperature which dissipates any liquid droplets that may have accumulated on the slider. After the liquid droplets have dissipated, the slider may again be loaded onto the magnetic disk.

摘要： Methods of performing nanoimprint lithography are described. For one method, a master tool and a stamper tool are formed to provide nanometer-scale imprinting. A release layer comprised of a perfluoropolyether diacrylate material is formed on the master tool and the stamper tool. The master tool and the stamper tool are used to form patterns in resist material, such as hole or pillar patterns. The resist material as described herein has lower viscosity and lower surface tension than prior resist materials allowing for more uniform replication of the patterns.
