ABSTRACT:
A transducer module for a disk drive having a magnetic read/write head supported by a slider which is maintained at a predetermined distance from a rotating disk by an air bearing. The slider is secured to a flexible gimbal within a protective housing. A second flexible gimbal is also secured to the inside of the protective housing and is preloaded to bias the head toward the rotating disk through a pivot, enabling the slider to position itself properly in response to the air flow at the surface of the disk. Means are also provided for retracting the head through a second pivot. With such an arrangement the housing protects the head mechanisms and, when mounted on an actuator arm, allows extension and retractions of the head along an axis perpendicular to the disk surface.
