Abstract:
1. A disk drive comprising: a head-slider, said head-slider configured to fly above a disk; an actuator, said actuator configured to support said head-slider and to swing about a pivot shaft to move said head-slider in a radial direction of said disk; a ramp on which said actuator is configured to rest in a stand-by position; and a shroud comprising an inner peripheral side surface and an outer peripheral side surface, said shroud having a portion where spacing between said inner peripheral side surface and said outer peripheral side surface decreases in a direction from said pivot shaft toward said head-slider and configured to control an air-stream which flows in a direction from said pivot shaft toward said head-slider, wherein said inner peripheral side surface and said outer peripheral side surface are configured to blast said head-slider with said air-stream upon spinning said disk when said head-slider is positioned away from said disk in said stand-by position, wherein at least a portion of at least one of said inner peripheral side surface and at least a portion of said outer peripheral side surface is configured to overlap said actuator at said stand-by position as viewed in a direction of said pivot shaft.
