Filed: 1953-03-10
Abstract: 730,823. Magnetic structures. ILLINOIS INSTITUTE OF TECHNOLOGY, ARMOUR RESEARCH FOUNDATION OF. March 10, 1953, No. 6560/53. Class 38 (2). [Also in Group VIII] A magnetic impulse record member comprises a thin flexible non-magnetic strip with a smooth surface having a coating 0.0001- 0.001 inch thick of material consisting of at least three parts of magnetic particles to one of binder, said particles having a maximum dimension less than 6 microns and a coercive force of at least 200 oersted, there being a sufficient amount of wax-like material associated with the magnetic coating to impart a smooth surface to reduce the abrasive action of the magnetic particles on the magnetic heads. The wax-like material may be natural or synthetic waxes, higher fatty acids and other hydrophilic agents having similar lubricating properties. On the base which may be a tape, disc or belt of paper, cellulose acetate, aluminium or glass;, is applied an undercoating which may be of waterinsoluble material such as cellulose nitrate, cellulose acetate or alkyd resin lacquer, or a water-soluble material of the kind forming the binder of the next, magnetic particle bearing, layer. These binders may be water-soluble or dispersible organic adhesives such as casein, gelatine or starches, e.g. soya bean flour. The solution of casein in water may be helped by the addition of ammonium' hydroxide, sodium carbonate, sodium hydroxide, borax, trisodium phosphate, or calcium hydroxide, and an antifoam agent such as pine oil may be added. The coatings may be applied warm, on one or both sides of the base, by brush, rolls, or blades. The undercoating and magnetic coatings may be rendered water-resistant by treatment with alum or formaldehyde. The undercoating may be loaded with barytes, clay, lamp black, titanium dioxide or lithopone. The coatings may be smoothed by calendering. The mag-. netic particles may be of iron oxide less than 1 micron in maximum dimension. To reduce abrasion in use, a water emulsion of beeswax, paraffin wax, carbowax, or the microcrystalline waxes recovered from petroleum refining are incorporated in the magnetic coating. To make the record medium more pliable, a softening agent such as a solution of glycerol or other water-soluble polyhydric alcohol, e.g. ethylene glycol monoethyl ether is incorporated in one or both coatings. A final coating of bees., carnauba-, or paraffin-wax may be applied by a revolving brush or roll prior to a final polishing. Other water-repellant substances such as stearic acid and emulsifying agents such as borax, soap, lye, ammonia, or sodium carbonate may be used. Magnetic powder of lower coercivity than that in the main magnetic coat maybe incorporated in the undercoat.
