Abstract
Abstract In a magnetic disk drive heads are loaded and unloaded onto the magnetic disk by wings attached in close proximity to the magnetic heads. The wings are cylindrical rods which ride on opposed ramps to separate the heads so that they can travel on either side of the disk and the heads are then brought together properly onto the disk. The wings are attached to the suspension arms of a Winchester head assembly by an attachment device having a tapered notch with an interference fit which secures the rods.
