    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 magnetic recording medium is formed with a distribution of low coercivity regions functioning as a transition pattern for servo information capable of being sensed by a read/write head by exposing a masked magnetic layer to ions to change the coercivity of the exposed magnetic layer without substantially affecting the topography of the magnetic layer.Embodiments of the present invention include forming a series of substantially radially extending low coercivity regions used to divide the magnetic layer into a plurality of sectors comprising substantially concentric circumferentially extending data tracks by exposing a masked magnetic layer having a high coercivity, i.e. from about 2000 Oe to about 10000 Oe, to one or more heavy atom ion bombardments of gaseous ions, e.g. argon ions, at a dose of about 1×1013 atoms/cm2 to about 9×1015 atoms/cm2 having an implantation energy of about 10 KeV to about 50 KeV.
