20090061735 | SYSTEMS AND METHODS FOR IN-SITU RECORDING HEAD BURNISHING - 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. | 03-05-2009 |
20090284861 | DISSIPATION OF LIQUID DROPLETS IN A MAGNETIC DISK DRIVE - 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. | 11-19-2009 |
20100117256 | SELF-RELEASING RESIST MATERIAL FOR NANO-IMPRINT PROCESSES - 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 polyakylene 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. | 05-13-2010 |
20100226035 | ABS WITH LUBRICANT CONTROL TRENCHES FOR HARD DISK DRIVES - 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. | 09-09-2010 |
20110102940 | SYSTEM, METHOD AND APPARATUS FOR PLANARIZING SURFACES WITH FUNCTIONALIZED POLYMERS - 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.

A multilayered disk overcoat is used to protect the recording layer, and at least one of the overcoat layers functions as a stop layer for terminating a chemical-mechanical polishing (CMP) process that substantially planarizes the disk. All of the layers of the multilayered overcoat are located above the lands, but none of the overcoat layers, or a number of layers less than the number of layers over the lands, is located above the recesses. | 10-06-2011 |
