ABSTRACT:
A read/write head for an information recording apparatus having a liquid bearing lubricant between a rotating storage medium and the read/write head is disclosed. The head is provided an actuator to position the read/write head over the rotating storage medium. The head includes a slider body having at least a first and second regions; and an interface element comprising a transducer interacting with the storage medium and mounted on the first region of the slider body. A relative motion exists between the head and the rotating storage medium and the slider body is supported by the liquid bearing lubricant during such motion, such that the first region of the slider body is supported at a first distance above the storage medium, and the second region of the slider body is supported at a second distance above the storage medium, whereby the first region of the slider body has a substantially higher drag than the second region when the head moves relative to the storage medium.
