Abstract
Windage is the sum of multifarious airflows induced and endured inside a disk drive. The invention provides a disk drive suspension and method for use in windage conditions within a disk drive. The suspension has a base portion carrying a hinge portion that carries a beam portion having oppositely facing first and second surfaces. The second surface supports a flexible circuit. Where the beam portion first surface has surface features inducing tracking error-causing perturbations of the beam portion from windage contact with the features, an airfoil profile-defining deflector is provided in operative association with the beam portion to block windage contact with those features and eliminate track misregistration error caused by interaction of the windage and the features.
