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.

Nanochip, Inc. - Fremont CA

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:

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.

Appl. No.:

11/688806

Inventors:

Donald Edward Adams - Pleasanton CA, US
Robert N. Stark - Saratoga CA, US

Assignee:

NANOCHIP, INC. - Fremont CA

International Classification:

G11B 9/00

US Classification:

369126

Abstract:

A system for storing information comprises a media including a ferroelectric layer, a tip arrangeable in electrically communicative proximity to the media, and circuitry to detect a polarization signal having a radio frequency. The polarization signal corresponds to changes in polarization of domains of the ferroelectric layer at a relative velocity of movement between the tip and the media, wherein a domain of polarization of the ferroelectric layer is information.
