Abstract
A 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 cross-tie, Bloch-line pair transfer system for bit-serially moving a bit-defining-Bloch-line along the cross-tie wall into a memory segment; a noise-cancelling figure-8 sense line that straddles the cross-tie wall; a hard axis drive field H.sub.T that passes, if in existence, a bit-defining-Bloch-line out of the memory segment into one of the loops of the sense line and thus inducing in the sense line loop an output signal that is indicative of the passing, or not, of the Bloch-line into the sense line loop.
