By Francis Pelletier on 2016.09.14
UltraCard, Inc., Berd, OR, has been assigned a patent (9,430,727) developed by Mann, Donald C., Thousand Oaks, CA, and Cook, Jr., Bert D., Morgan Hill, CA, for a "data storage device, apparatus and method for using same."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A data storage device serving as a portable card, magnetically encodeable card, or a magnetic credit card is shown. The data storage device includes a substrate having at least one surface. A high density, magnetically coercive material layer is disposed on or is deposited on the substrate for storing magnetic signals. The magnetically coercive material may have an axis of magnetization that is oriented in a predetermined direction relative to the at least one surface of the substrate. A layer of non-magnetically material is disposed on the substrate for defining an exchange break layer. A relatively hard, abradeable protective coating is formed on the magnetic material layer and has a thickness between a maximum thickness that materially attenuates magnetic signals passing between the magnetic material layer and a transducer and a minimum thickness enabling the protective coating to be abraded by usage in an ambient natural atmosphere operating environment."
The patent application was filed on February 12, 2013 (13/765,659).
