摘要： An apparatus includes a slider body having a leading edge and an opposite trailing edge, as well as a top face and a bottom face each extending between the leading edge and the trailing edge. The slider body further includes a plurality of protrusions extending from the bottom face, a first recess defined on one of the protrusions, and a sacrificial layer deposited on the slider body in the recess. A bottom surface of the sacrificial layer extends at least as far from the bottom face as bottom surfaces of the plurality of protrusions. In another aspect, a first blocking feature is located at a first uptrack edge on an air bearing surface of a slider, with the first blocking feature being substantially continuous along the first uptrack edge and protruding outwardly from the air bearing surface to reduce particle interaction with the air bearing surface.

摘要： A method is disclosed for producing sliders with protective contacts features the fabrication of which is initiated at the wafer level. Recesses are formed in the wafer, a protective material is provided in the recesses, and the wafer is sliced along the recesses and diced into sliders, such that the protective material forms corners of the sliders. The protective material may be disposed such that it has a low elastic modulus at the corners, and a higher elastic modulus at a displacement from the corners which is still lower than the elastic modulus of the slider body, thereby providing superior protection for potential contacts between the slider and an adjacent media surface.

摘要： A multi-stage sensor is situated on the head transducer and configured to interact with a magnetic recording medium. A first sensor stage of the multi-stage sensor has a temperature coefficient of resistance. A second sensor stage of the multi-stage sensor is coupled to the first sensor and has a temperature coefficient of resistance. The first sensor stage is configured to preferentially sense asperities of the media relative to the second sensor stage, and the second sensor stage configured to preferentially sense proximity to, and contact with, a surface of the media relative to the first sensor stage. The first and second sensor stages may be connected in series or in parallel.

摘要： A data recording component includes a read transducer and a write transducer. A thermoelectric device generates heat flow between the read transducer and the write transducer. The heat flow is conducted by thermal conductors. A controlled current source provides current to the thermoelectric device that changes polarity to change directions of the heat flow and thereby vary a gamma ratio of transducer protrusion.
