摘要： An information storage system having a ring head in such close proximity to a rigid magnetic storage disk that the magnetic field felt by the media layer or layers of the disk has a larger perpendicular than longitudinal component so that data is stored in a perpendicular mode. Reading of data is accomplished with a magnetoresistive sensor which may be coupled to the magnetically permeable core of the ring head far from the poletips, which may contact the disk. The media preferably has a high perpendicular anisotropy, and may be formed in a plurality of films with crystalline structures traversing the films.

摘要： A transducer for a hard disk drive system has a planar magnetic core and a pair of poletips that project transversely from the core for sliding contact with the disk during reading and writing. The transducer is formed entirely of thin films in the shape of a low profile table having three legs that slide on the disk, the poletips being exposed at a bottom of one of the legs for high resolution communication with the disk, the throat height of the poletips affording sufficient tolerance to allow for wear. The legs elevate the transducer from the disk sufficiently to minimize lifting by a thin air layer that moves with the spinning disk which, in combination with the small size of the thin film head allows a low load and a flexible beam and gimbal to hold the transducer to the disk. The transducer includes a loop shaped core of magnetic material that ends at the poletips, the core extending further parallel than perpendicular to the disk surface and preferably being formed of a plurality of slightly spaced ribbons of magnetic material in order to increase high frequency permeance. A high magnetic saturation layer may be formed adjoining the gap in at least the trailing poletip, in order to avoid saturation at the poletips during writing. The dimensions of the yoke adjacent to the poletips are also designed to avoid saturation at the poletips by saturating at a lower flux in the yoke than the poletips. The close relationship between the transducer and the media of the disk affords high density magnetic data storage and retrieval.

摘要： A light modulator and a method of manufacturing the same are provided having a continuously deformable optical surface. Generally, the modulator includes a substrate, a membrane disposed above and spaced apart from an upper surface of the substrate, the membrane having a continuously deformable light reflective surface formed on its upper side facing away from the upper surface of the substrate, and a means for deflecting the deformable surface relative to the substrate. Light reflected from different points of the deformable surface can interfere to modulate light reflected from the modulator in 0th order applications. In one embodiment, the membrane includes a static reflective surface surrounding the deformable surface. Light reflected from the static surface and the deformable surface can interfere to modulate light reflected from the modulator in non-0th order applications. Preferably, the static surface is substantially planar and the deformable surface are sized and shaped to define substantially equal areas. In one embodiment, the static surface circumscribes the deformable surface to define a parabolic reflector.

The layers include at least a top surface for receiving incident light, a first layer overlying the substrate, and a second layer between the top surface and the first layer, the second layer overlying and abutting the first layer.

摘要： A holographic data storage (HDS) system and method are provided. Generally, the system includes: a light source for generating a coherent light; beam-forming optics for forming the light into collimated object and reference beams; holographic storage medium; a spatial light modulator (SLM) located in a path of the object beam from the beam-forming optics to the storage medium, the SLM having a number of pixels for encoding data to be stored in the medium into the object beam. Preferably, the SLM can modulate both the amplitude and phase of light from every pixel on the SLM. More preferably, the SLM is also located in a path of the reference beam to the storage medium to modulate the phase of the light to store multiple holographic pages of data in the same physical volume of medium through phase multiplexing. Other embodiments are also described.

摘要： In one embodiment, a capacitive micro electro-mechanical systems (MEMS) device includes a dielectric spacer between a bottom electrode and a movable member. The movable member may serve as a top electrode. A gap separates the top electrode from the dielectric spacer. The movable member may be actuated to deflect towards the bottom electrode by electrostatic force. The dielectric spacer reduces the height of the gap that would otherwise be formed between a top surface of the bottom electrode and a bottom surface of the movable member, thereby improving squeeze-film damping. The movable member may be a ribbon of a ribbon-type diffractive spatial light modulator, for example.

摘要： An information storage system includes a transducer having a loop of ferromagnetic material with pole tips separated by an nonferromagnetic gap located adjacent to a medium such as a rigid disk. During writing the separation between the pole tips and the media layer of the disk is a small fraction of the gap separation. Due to the small separation between the pole tips and the media layer, the magnetic field generated by the transducer and felt by the media has a larger perpendicular than longitudinal component, favoring perpendicular recording over longitudinal recording. The media may have an easy axis of magnetization oriented substantially along the perpendicular direction, so that perpendicular data storage is energetically favored. The transducer may also include a magnetoresistive sensor for reading magnetic information from the disk.

摘要： A spatial light modulator is provided having a two-dimensional (2D), close-packed MEMS (Micro-Electromechanical System) array of diffractive pixels. Each pixel includes a number of diffractive elements or diffractors. Each diffractor includes a tent member disposed above and spaced apart from an upper surface of a substrate, a movable actuator disposed between the substrate and the tent member, and a driver moving the actuator. The tent member has a first planar light reflective surface facing away from the substrate, the first planar light reflective surface having an aperture formed therein. The actuator has a second planar light reflective surface parallel to and potentially coplanar with the first planar light reflective surface and positioned relative to the aperture to receive light passing therethrough. The aperture may be sized and shaped to define an area with reflectivity substantially equal to the reflectivity of an area of the first planar light reflective surface surrounding the aperture to provide a maximum contrast ratio.
