Filed:

Dec 3, 2004

Appl. No.:

11/003955

Inventors:

Thomas F. Rust - Oakland CA, US
Robert N. Stark - Saratoga CA, US
Thomas L. Noggle - Oakland CA, US
Daniel F. Cribbs - Los Gatos CA, US

Assignee:

Nanochip, Inc. - Fremont CA

International Classification:

G11B 9/00

US Classification:

369126, 369 3001

Abstract:

Methods in accordance with the present invention can be applied, in an embodiment, to a media comprising a phase change material to alter a resolved portion of the phase change material to have a resistance different from a resistance of the bulk material. A tip having a substantially larger radius of curvature than the resolved portion can be employed by applying such methods. A substantially anisotropic columnar material can focus a current applied between the tip and the media so that the portion is narrower in width than the radius of curvature. Such highly resolved portions form bits in the media. Other objects, aspects and advantages of the invention can be obtained from reviewing the figures, specification and claims. This description is not intended to be a complete description of, or limit the scope of, the invention.

International Classification:

G11B 9/00

US Classification:

369126, 369288

Abstract:

A data storage device comprises a media including a memory layer within which are formable domains associated with information, and a conductive layer disposed over the memory layer, the conductive layer having anisotropically increased electrical conductivity in a thickness direction. A conductive tip contactable with the conductive layer is adapted to form domains within the memory layer and one of the conductive tip and the media is movable to access the memory layer.

International Classification:

G11B 9/02

US Classification:

369126, 977947

Abstract:

An arrangement, a method and a system to read information stored in a layer of ferroelectric media. The arrangement includes a layer including a ferroelectric media having one or more ferroelectric domains holding bit charges, a domain corresponding to information; a probe having a tip, wherein the media and the tip are adapted to move relative to one another such that the tip scans the ferroelectric domains of the media while applying a contact force to the domains to generate a direct piezoelectric effect within the domains; and circuitry coupled to the tip and adapted to generate a signal in response to an electrical coupling between the tip and the domains while scanning the tip in contact with the domains, the signal corresponding to a readout signal for ferroelectric bit charges stored in the media.

US Classification:

3592241, 3591991, 3591993, 3592007, 310 48, 310208

Abstract:

Implementations of actuators and capacitor-based position sensors for monitoring and controlling positioning of the actuators are provided, including implementations of actuators that use flexures to provide support to actuators and pivoting mechanisms to the actuators. Such actuators can be electromagnetically activated actuators that include a magnet stator and a coil rotor mounted on a flexure. A positioning sensor, such as a capacitor sensor, is provided to measure and monitor positioning of the actuator and is coupled to a feedback circuit which uses the measured positioning of the actuator to control the actuator.

International Classification:

H02P007/06

US Classification:

365232000

Abstract:

Systems in accordance with the present invention can be include, in an embodiment, one or more tips and a media comprising an over-layer, an under-layer, and a phase change material disposed between the over-layer and under-layer. Portions of the phase change media which can be altered to have a resistance different from a resistance of the bulk material, thereby forming highly resolved bits. A distal end of the tip can have a substantially large radius of curvature relative to a width of the resolved portion. Other objects, aspects and advantages of the invention can be obtained from reviewing the figures, specification and claims. This description is not intended to be a complete description of, or limit the scope of, the invention.
