Abstract
Implementations described and claimed herein includes a storage device comprising a transducer heat including at least one pair of read/write elements and a heat shaped 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.
Claims20
Apparatus comprising:
- a transducer head including a pair of read/write elements;
- and
- a heat element for creating a thermally protruded close point on the transducer head, the heat element including 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.
A storage device comprising:
- a storage medium;
- a transducer head including a pair of read/write elements;
- and
- a heat element for protruding the read/write elements toward the storage medium, the heat element including a conductive portion of locally decreased resistance and a conductive portion of locally increased resistance in a same plane parallel to an air-bearing surface of the transducer head, the portion of locally decreased resistance positioned between the read/write elements of the pair.
A method comprising:
- selecting a first element of a read/write element pair to perform a data access operation;
- directing current through a heat element to thermally protrude the selected read/write element from an air-bearing surface of a transducer head, the heat element including at least one conductive portion of locally increased resistance and at least one conductive portion of locally decreased resistance that intersect a same axis parallel to the air-bearing surface, the portion of locally decreased resistance positioned between the first element and a second element of the read/write element pair.
