Patent ID: 8520339

Claim:
A magnetic storage system comprising: a slider body having an air-bearing surface defined by a leading edge, a trailing edge, and two side edges connecting the leading and trailing edges; a transducer arranged toward the trailing edge of the slider body, said transducer comprising a heat-induced protrusion for displacing one or more elements of transducer out from the slider body; and a trench on the air-bearing surface proximate to the trailing edge, the trench positioned adjacent to the transducer so as to divert air passing over the air-bearing surface of the slider body immediately before the air passes over the transducer, thereby reducing cooling effect on the transducer and preventing degradation in stroke efficiency of the heat-induced protrusion, wherein the trench is directly formed in the air-bearing surface and the transducer is directly formed to the air-bearing surface such that the trench is located immediately upstream of the transducer, wherein the trench comprises a floor and two side faces protruding from the floor to define an opening to receive the air diverted from the transducer, wherein a first of the two side faces is oriented toward the leading edge and a second of the two side faces is oriented toward the trailing edge, the first side face having a greater depth than the second side face.
