  • 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.
