Abstract
A head gimbal assembly (10) for a disk drive (1), having a flexure (30) with a stationary portion (40) and at least one movable portion (42), a portion of the flexure (30) being attached to a load beam (28). A slider (20) containing a read/write head (22) is attached to one of the movable portions (40) of the flexure (30). The load beam (28) provides a center of rotation (54) for the slider (20) and one or more microactuators (24) connect between the stationary portion (40) of the flexure (30) and one of the movable portions (42, 44) for applying a moment which causes pure or nearly pure rotation of the slider (20) about the center of rotation (54).A disk drive (1) and an actuator arm (2) including the head gimbal assembly (10) are also disclosed.
