High Density Magnetic Bubble Memory Techniques.

Abstract

Several material compositions have been investigated with the goal of obtaining a material suitable for operation in devices requiring bubble domain diameters of approx 1 micrometer. An YSmTmGaIG composition has shown attractive material properties and has been submitted for device evaluation. Analysis of self-biased structures has been performed. The results show a dependence of the effective bias field on the quality factor q. This analysis has provided improved criteria for selection of the optimum parameters for temperature stable self-biased materials/devices. Component designs for a hybrid decoder chip and a wafer level integration approach to a high capacity chip have been completed. A test chip incorporating several versions of the components has been submitted for fabrication and evaluation. A conceptual study of a 10 to the 12th power bit data storage system has been initiated. (Author)
