A disk drive includes a head gimbal assembly that includes structure that decreases
the pitch angle of the load beam, which decreases disk flutter induced track mis-registration.
According to one embodiment, the disk drive includes a body portion including a
bore defining a pivot axis; an actuator arm cantilevered from the body portion
and a head gimbal assembly (HGA) supported at the actuator arm. The HGA includes
a load beam having a first end and a second end, the first end being attached to
the actuator arm, the load beam defining a load beam feature near the second end,
at least a portion of the load beam feature defining an extension that is parallel
to the pivot axis and that has a rectangular cross-section having a length to width
aspect ratio that is greater than 1. A slider is coupled to a free end of the load
beam extension, and a gimbal coupled to the second end of the load beam and to
the slider.
