ABSTRACT:
A slider for attachment to a flexure of a disc drive system includes a slider body, a transducing head formed on the trailing edge of the slider body, and a microactuator formed on the leading edge of the slider body. The microactuator engages the flexure to rotate the transducing head in response to control signals applied to the microactuator. The slider is applicable to achieve fine positioning of the transducing head in a disc drive having an actuator arm supporting the flexure and a motor operable to move the actuator relative to a disc to coarsely position the transducing head. The microactuator and the transducing head may be formed by thin film deposition.
