ABSTRACT:
A punched gimbal dimple with a coined, frusto-conical base in a head suspension and a method for producing such a dimple. The dimple has an apex and a base, the base having outer and inner surfaces which generally conform to conical frustums. The conical frustum half-cone angles differ by at least 2 degrees. The dimple and its coined base are fabricated by a dimple punch and die with mismatched punch tangent and chamfer angles. The coined dimple base can be more easily seen by optical systems for aligning a slider to the dimple.
