ABSTRACT:
A magnetoresistance detector linearly stretching single bits of binary inmation such as those represented by Bloch line - crosstie pairs, along the major dimension of a thin magnetic film strip such as a serriform crosstie memory. The detector circuit is overlaid upon the thin magnetic film strip. In a selected area, less pronounced serrations in the adjacent margins, in conjunction with a magnetic field created by current through the detector circuit enable Bloch lines entering the area to travel farther. A series of oriented open segments in the overlain section of the detector circuit, arranged in symmetric correspondence with serrations in the adjacent margins, enhances the difference between logical zero and one signals in the detector circuit.
