    摘要： A method of performing thermal imprint lithography of a surface of a thermoplastic layer-coated workpiece for forming a pattern therein comprises pre-heating the workpiece to a pre-selected high temperature prior to inserting the workpiece in a stamping/imprinting tool maintained at a predetermined lower temperature, whereby the interval for thermal cycling of the stamping/imprinting tool between higher and lower temperatures is eliminated or at least reduced. Applications of the method include forming servo patterns in disk-shaped substrates for hard disk recording media.

    摘要： An elastomer pad used in a system and method for servo formatting magnetic media using contact magnetic printing is disclosed. The elastomer pad includes a substrate substantially the same shape and size as the magnetic media and an elastomer material bonded to the substrate wherein the substrate provides support for the elastomer material. Further an apparatus for creating magnetic patterns on magnetic media, including the elastomer pad, is disclosed and includes a stamper having a pattern, a press for supplying a force to the stamper and the magnetic media, the elastomer pad including the substrate and bonded elastomer material, positioned between the stamper and the press for enabling the stamper to conform to the contours of the unflat stamper, and a magnet for supplying a magnetic field to the stamper and the magnetic media causing the pattern on the stamper to be transferred to the magnetic media.

    摘要： A stamper/imprinter for use in performing thermal imprint lithography of a substrate/workpiece surface to form a pattern of features in first portions of the surface intended to receive the pattern, without incurring random formation of undesired, disordered features in second portions of the substrate/workpiece surface not intended to receive the pattern, comprising an imprinting surface configured to substantially prevent formation of gaps between the imprinting surface and the second portions of the surface during stamping/imprinting. Embodiments include stampers/imprinters with a multilevel imprinting surface comprises a first portion having a first level for forming the pattern of features in the first portions of the surface and a second portion having a second level for substantially preventing formation of gaps between the imprinting surface and the second portions of the surface during stamping/imprinting.
