  • Transducing head protrusion control
    Patent number: 10332549
    Abstract: A slider includes a reader element, a bottom shield located adjacent to the reader element, a top shield located adjacent to the reader element, a heater, a substrate located below the reader element, the top shield, the bottom shield and the heater, and a cap substantially surrounding the reader element, the top shield, the bottom shield and the heater. The cap includes a base coat layer comprising a first electrically insulative cap material adjoining the substrate, and an overcoat layer comprising a second electrically insulative cap material adjoining the base coat layer opposite the substrate. The base coat layer and the overcoat layer meet at an interface located at or below the top shield. The first and second electrically insulative cap materials are different.

  • Heater design with locally decreased resistance area for fly height control
    Patent number: 10204645
    Abstract: Implementations described and claimed herein includes a storage device comprising a transducer head including at least one pair of read/write elements and a heat element to thermally protrude regions of the transducer head including the read/write elements. According to one implementation, the heat element includes at least one conductive portion of locally decreased resistance proximal to and between the pair of read/write elements to direct the thermally protruded close point away from a midpoint between the read/write elements.

  • Slider design for diverting airflow away from a transducer
    Patent number: 8520339
    Abstract: This disclosure is directed to air-bearing sliders used in magnetic storage systems that employ a trench arranged between a transducing head connected to a slider body and a leading edge of the slider body. The trench is configured to divert air passing over an air-bearing surface of the slider body away from the transducing head.
