Abstract: An information layer for an optical information storage medium is formed in a centrifuge. A photopolymerizable composition is applied to a solid base having a relief pattern, and a flexible, transparent film layer is applied on top of the composition. The three are spun in a centrifuge to cause a thin, even distribution of the photopolymerizable composition, which is photopolymerized. The resulting replica is separated from the relief pattern and has a fluorescent material applied thereto. Alternatively, the replica has a non-fluorescent material applied thereto, and the non-fluorescent material is made fluorescent through diffusion. Multiple information layers thus formed can be glued together to form a multilayer optical information storage medium.

Abstract: A direct-write method for fabricating magnetic nanostructures, including hard magnetic nanostructures of barium hexaferrite, BaFe, based on nanolithographic printing and a sol-gel process. This method utilizes a conventional atomic force microscope tip, coated with a magnetic material precursor solution, to generate patterns that can be post-treated at elevated temperature to generate magnetic features consisting of barium ferrite in its hexagonal magnetoplumbite (M-type) structure. Features ranging from several hundred nm down to below 100 nm were generated and studied using AFM, magnetic force microscopy, and X-ray photoelectron spectroscopy. The approach offers a new way for patterning functional inorganic magnetic nanostructures with deliberate control over feature size and shape, as well as interfeature distance and location.

Further, gaps between the divided recording elements are filled with a non-magnetic material before removing the first mask layer.

Abstract: An optical antenna collects, modifies and emits energy at light wavelengths. Linear conductors sized to correspond to the light wavelengths are used. Nonlinear junctions of small dimension are used to rectify an alternating waveform induced upon the conductors by the lightwave electromagnetic energy. The optical antenna and junctions are effective to produce harmonic energy at light wavelengths. The linear conductors may be comprised of carbon nanotubes that are attached to a substrate material, which may then be connected to an electrical port.

Abstract: As track widths of magnetic read heads grow very small, conventional longitudinal bias stabilization has been found to no longer be suitable since the strong magnetostatic coupling at the track edges also pins the magnetization of the free layer. This problem has been overcome by extending the free layer so that it is no longer confined to the area immediately below the spacer or tunneling layer. A longitudinal bias layer immediately below the free layer is given a relatively weak magnetic exchange coupling field of about 200 Oe. Although there is strong exchange coupling between this and the free layer, the degree of pinning of the free layer is low so that the device's output signal is reduced by less than about 10%. A process for manufacturing both the CPP SV and a MTJ versions of the invention is described.

Abstract: A vacuum deposition system has been designed to produce thin film based demultiplexers with high throughput and production yields of greater than 25% for use in Dense Wavelength Division Multiplexer (DWDM) systems. The system employs a dense array of high yield fixtures and an ion assisted movable dual electron beam evaporation system. The fixture array increases acceptable yields of narrow band pass filters to 25–75% compared to less than 5% in conventional coating systems used for DWDM. The movable e-beam system allows critical symmetry to be maintained while eliminating significant delays resulting from deposition of two materials from a single electron gun. The vacuum deposition system will enable production of more than 15,000 50–200 GHZ filters which meet specifications for DWDM demultiplexers every 48 hours.
