    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: 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.

    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 recording disks and associated fabrication methods are described for utilizing polymer structures in planarized magnetic media. A polymer fill material is deposited on the disk and a removal process is performed on the fill material to planarize the disk. In some embodiments, the fill material is deposited subsequent to bonding a lubrication layer to a protective layer on the disk. In other embodiments, the fill material is bonded directly to a protective layer on the disk.

    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: 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: 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.
