  • Magneto-resistive head with reduced thermal noise
    Patent number: 4683508
    Abstract: To lessen thermal noise in a magneto-resistive head employing a slotted magneto-resistive sensing element, the present invention provides for such element to be plated with a highly thermally conductive film (e.g. gold, silver, copper, aluminum, etc.) exclusively in the slotted portion of the element. By restricting such plating to the slotted portion of the sensing element, the film thereon will be precluded from electrically short circuiting the magneto-resistive sensing element . . . while, at the same time, serving as an energy-spreading heat sink.
