Abstract

1,023,873. Magnetic storage apparatus. RADIO CORPORATION OF AMERICA. May 13, 1963 [June 11, 1962 (2)], No. 18869/63. Heading H3B. [Also in Division H1] A sheet of ferrite material 20 (Fig. 6) having its two major surfaces parallel has at least one conductor 14 embedded in it so that an exposed surface of the conductor lies flush with one of the major surfaces of the sheet. The ferrite is in the green state and may be bonded under pressure and heat with other sheets of green ferrite 22, 24, the latter of which incorporates an embedded conductor 26, the building material being then burnt out and the sheets being then raised to sintering temperature and subsequently air quenched or annealed in nitrogen. The conductor 26 may include portions extending parallel with each of the three conductors 14. A large number of conductors and memory locations may be provided in each composite sheet 30. The conductors may be of palladium, rhenium, rhodium, platinum or alloys thereof and the ferrite of zinc, magnesium and manganese oxides with an organic binder and a methyl ethyl ketone solvent. The conductors may be deposited on a beryllium copper sheet 10 (Fig. 4, not shown) by a photo-resist process and covered with ferrite slurry, the copper sheet 10 being subsequently etched away. The ferrite may be spread by a doctor blade, a callendar roll or a spray gun. Alternatively a paste of powdered conducting material mixed with petroleum grease may be deposited through a stencil 40 (Fig. 9, not shown) on to a substrate 46 to form conductors 44 which are subsequently covered with a layer of ferrite slurry which is dried and peeled off the substrate bringing with it the conductors which are wider at their inner surfaces. Some of the petroleum grease is dissolved out of the conductors so that shrinkage of the ferrite occurring when the composite member is sintered after suitable sheets have been bonded under pressure, compacts the conductive powder.
