Abstract
1357864 Magnetic storage devices AMPEX CORP 3 Oct 1972 [5 Oct 1971] 45583/72 Heading H3B A plurality of storage matrices 0 to 17, Fig. 3, are each composed of a double herringbone pattern of storage cores 30 and together form a planar storage array with corresponding row and column conductors X, Y of the individual matrices connected in series, a separate sense loop SO, SO having a centre tap connected to an inhibit line 10 being provided for each matrix. The array of matrices is mounted by a substrate 14 on a printed circuit board 12, Fig. 1, with an overlying cover 16, the board having a different conductor pattern on each of its major surfaces which terminate in respective plug connectors 22 along one edge. Depending on which conductor pattern is adjacent the substrate 14, arrays of different numbers of matrices may be wired in through the adjacent pattern to the connectors. Terminal pads are provided through each conductor pattern for diode decoder circuits 50, Fig. 7, the centre taps 2 to 5 and 9 to 12 being each connected to one end of an X or Y matrix conductor and the terminals 1 and 14 being connected to negative and positive voltages, respectively. Each diode decoder circuit is assembled as a package 49, Fig. 8, with downward extending leads S1 for attachment to the printed circuit terminal pads. Various arrangements of matrix winding and energization are discussed.
