    摘要： A method of fabricating a master stamper/imprinter for manufacturing a patterned recording medium by nano-imprint lithography comprises steps of: (a) providing a substrate having a surface; (b) forming a layer of a hybrid resist material on the surface, the resist layer having an exposed upper surface; (c) subjecting selected areas of the exposed upper surface of the resist layer to an energy beam to form therein a latent image of a topographical pattern to be formed in the resist layer and having a correspondence to a pattern to be formed in a patterned recording medium; and (d) developing the latent image into the topographical pattern in the resist layer, wherein only those areas of the resist layer which have received an energy beam exposure dose between a positive-tone threshold dose D0p and a negative-tone threshold dose D0n are developed.

    摘要： A method of forming a magnetic transition pattern in a longitudinal magnetic recording medium, comprising steps of: (a) providing a magnetic recording medium including a layer of a magnetic material having a surface comprised of a plurality of longitudinally extending magnetic domains; (b) contacting the surface of the layer of magnetic material with a topographically patterned imprinting surface of a stamper/imprinter formed of at least one high saturation magnetization, high permeability magnetic material; and (c) applying a unidirectional magnetic field perpendicular to the imprinting surface of the stamper/imprinter, the perpendicular magnetic field creating a longitudinal magnetic field component of sufficient strength to effect selective alignment of the magnetic domains of those portions of the layer of magnetic material which face the depressions of the imprinting surface while retaining the alignment of the magnetic domains of those portions of the layer of magnetic material which face the projections of the imprinting surface, the combination of portions forming a magnetic transition pattern replicating the topographical pattern of the imprinting surface.

    摘要： A method of imprint lithography includes imprinting a first pattern with a first template on a first substrate of a lithographic template. A second pattern is imprinted with a second template on the substrate of the lithographic template. The first pattern and the second pattern at least partially overlap, thus forming a third pattern. The third pattern is lithographically formed on a second substrate with the lithographic template. In an embodiment, the first pattern is a concentric line pattern formed by thin film deposition. In an embodiment, the second pattern is a radial line pattern. In an embodiment the first pattern and the second pattern may have line frequency increased.

    摘要： A polarization detection system structured for optical read-out of disc-shaped optical data/information storage and retrieval media with surfaces comprised of pits or marks configured as multilevel oriented nano-structures (ONS) with varying pit or mark orientations and widths. The polarization detection system comprises: an optical beam source; a stage for mounting and rotating an optical disc medium about a central axis; at least one photodetector; a beam splitter positioned in an optical path between the source and stage, for directing an incident beam from the source onto an optical disc mounted on the stage and a return beam from the disc onto the photodetector; and an optical polarizer positioned in an optical path between the beam splitter and the at least one photodetector, for detection and analysis of changes in polarization of the return beam effected by variation of the orientation of the walls and/or widths of the pits or marks of the disc.

    摘要： A patterned recording media is formed from a master template that includes a data area and a timing track area having a final timing track. In order to form the final timing track, a first timing track is etched into master template and tested for accuracy by comparing the angular position of the master template to the timing track. If errors are detected in the timing track, the errors are used to create additional timing tracks which are etched into the master template. This process of improving the timing track is repeated until a final timing track is formed that has errors below a predetermined level. The timing tracks formed prior to the final timing track are removed and the master template is used to make stampers which are used to make patterned media disks.

    摘要： Systems and methods are provided for correcting write synchronization of a magnetic storage device with respect to magnetic storage media and its corresponding writable magnetic bits, or dots. In particular, these systems and methods involve using time-shifting principles to calibrate the magnetic storage devices to correct slow drifts of reader-writer timing. It is to be appreciated that time-shifting techniques can be applied in a variety of manners. For example, the very dots on the media can be positioned in time-shifted fashion. In another example, the writing to the dots can be time-shifted.
