US Patent:

54853346, Jan 16, 1996

Filed:

Feb 22, 1996

Appl. No.:

8/392393

Inventors:

James L. Nix - Boulder CO
Guy F. Ruse - Boulder CO
Paul D. Reinholz - Westminster CO
Anthony C. Helms - Lafayette CO
Daniel J. O'Connor - Prior Lake MN

Assignee:

Quantum Peripherals Colorado, Inc. - Louisville CO

International Classification:

G11B 539
G11B 531

US Classification:

360113

Abstract:

An improved magnetoresistive device and method for fabricating the same which results in improved Barkhausen noise suppression. A generally coplanar device is described having an MR structure conductive region longitudinally biased by opposing permanent magnet layers separated therefrom by a non-magnetic metal or dielectric separation layer. significant reduction of the demagnetization energy near the MR-to-permanent magnet junction is achieved, particularly in the use of an elliptically shaped conductive region and the resultant generally coplanar device is readily fabricated and reproducible using a self-aligning process. The longitudinal bias technique described can be used in conjunction with all known transverse bias techniques.

Abstract:

A method for facilitating transactions by tenants in a multi-tenant architecture system is discussed. The method includes generating, with a multi-tenant computer system, a first representation of an entity in a first hierarchical data structure associated with an entity interface tenant of the multi-tenant computer system. The method includes receiving, with the multi-tenant computer system, a set of entity-specific policies useable to generate requests to individual ones of a plurality of transaction processing computer systems. The method includes generating, with the multi-tenant computer system, a second representation of the entity in a second hierarchical data structure associated with a particular transaction processing service tenant of a plurality of transaction processing service tenants of the multi-tenant computer system. The method includes linking, with the multi-tenant computer system, the first representation and the second representation in a unified hierarchical data structure useable to provide a unified identity for the entity for requests.
