  • Head suspension having a punched gimbal dimple with coined inclined inner and outer surfaces oriented at different angles and method of fabricating same
    Patent number: 7924530
    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.

  • Punched gimbal dimple with a coined periphery in a head suspension
    Patent number: 7907367
    Abstract: A punched gimbal dimple with an annular coined periphery extending outward from the dimple in a head suspension and a method for producing such a dimple. The dimple and its coined periphery are fabricated from a dimple punch and a die with a raised coining surface. The coined area on the dimple periphery can be seen by optical systems as a shiny ring, which is useful for aligning a slider to the dimple. The coined periphery is also less distorted by dimple punching than a non-coined periphery.
