Magnetic Memory Recording

The advantages of both magnetic tape recorders and core memory arrays are realized with this film memory.

In the upper drawing, a large number of wires 2 is strung in parallel between plates 4 held in parallel spaced relationship. This is by supports 6a... 6d mounted at the corners of each plate 4. Each wire 2 represents a common bit- sense line and is coated with a magnetic film. Mounted orthogonally to the parallel array of wires is movable word drive plane 8. This contains word drive lines 10 through which wire 2 passes. Drive 12, coupled to support 6d, a lead screw, moves plane 8 orthogonally to the array of parallel wires, enabling successive information blocks to be read or written into the array.

In the lower drawing, the memory consists of two co-planar plates. On larger stationary plate 22, a grid 24 of drive and sense lines is positioned. On smaller movable plate 20, there is a thin film of magnetic material. Lead screws 26 are connected to supporting block 28. This is superimposed over plate 20 permitting movement of it with respect to plate 22. Plate 20 first moves in a Y direction to the left one bit diameter with storing or sensing taking place during this movement. Plate 20 then jumps one bit diameter forward in the X direction during which time no recording is performed. Having reached a new X direction, plate 20 then moves in a Y direction one bit diameter to the right where further storing or sensing is performed. When...
