Abstract
A detector for non-destructive sensing of binary information at a selected location along a domain wall of a thin magnetic film strip. Voltages are applied across a set of contacts arranged along the margin of the strip and the value of the voltage measured at an arranged, centered contact indicates the presence or absence of a Bloch line-crosstie pair at that location.
