The purpose of this paper is to present two aerodynamically designed base castings that could substantially reduce disk flutter due to turbulent excitations in high-speed disk drives. The first design includes aerodynamic brackets to smooth the shroud contour and an extended shroud to reduce the shroud opening. The second design is a Velcro treatment to modify turbulence generation. Experimental results show that smoothing the shroud corners and reducing the shroud opening can reduce disk flutter by as much as 50%. Introducing a Velcro layer to the inner surface of the shroud can perturb the boundary layer and modify turbulent excitations
