Coined partial etched dimple in a head suspension and method of manufacture

摘要

A magnetic head suspension and method of manufacture of the type having a dimple formed in a surface of the head suspension. The dimple comprises a solid protuberance that is partial etched in a surface of the head suspension and then coined by engaging a socket with the partial etched protuberance to form a convex tip portion. The socket can have a hemi-spherical interior surface to form a hemi-spherical coined partial etched dimple. Alternatively, the socket can have a conical interior surface to form a conical coined partial etched dimple. The dimple can be formed on a slider mounting surface of a flexure to act as a static attitude compensation dimple. Alternatively, the dimple can be formed in a loading region of a load beam or in a cantilever region of the flexure to act as a load point dimple.
