Abstract
A slider support structure is disclosed for minimizing off-rack due to disk flutter. In one embodiment, the slider support structure includes a gimbal assembly (306). The assembly (306) includes an outer ring (500) and an inner ring (502). The outer ring (500) is connected to the inner ring (502) via narrow strips (504 and 506) adjacent to the front (508) and back (510) surfaces of the slider body (512). The inner ring (502) is attached to the left (514) and right (516) surfaces of the slider body (512) via narrow strips (518 and 520). The strips (504 and 506) interconnecting the inner ring (502) and outer ring (500) define a flexible hinge that allows the slider body (512) to pivot relative to the assembly (306) about an axis (522) which, in this case, is the roll axis. Similarly, the strips (518 and 520) define a flexible hinge which allows the slider to pivot relative to the assembly (306) about another axis (524) which, in this case, is the pitch axis. The axes (522 and 524) are disposed close to the lower surface of the slider so that head off-track associated with such pivotal is minimized.
