MAGNETO-INDICATIVE TRANSITIONAL TRANSITIONAL TRANSFER TRANSPORT SCHEME

摘要

The method of and a configuration for reading out the information that is stored in a cross-tie wall memory system is disclosed. The apparatus utilizes: a continuously, relatively long, sense line that is aligned along and straddles the cross-tie wall; a first polarity hard axis drive field HTt that passes, if in existence, a stored-1-representing-Bloch-line from a memory segment along the cross-tie wall into, along and past the continuous sense line; a second polarity hard axis drive field HTn that nucleates many Bloch-lines at once along the cross-tie wall in the area of the sense line for causing the nucleating Bloch-lines to induce in the sense line an output signal that is indicative of the change in polarity of the Neel wall vectors within the cross-tie wall in the area of the sense line and, accordingly, whether or not a stored-1-representing-Bloch-line had been stored previously in the memory segment.
