  • Precision limit stop for high density disk drives
    Patent number: 5864449
    Abstract: A limit stop for magnetic storage disk drive systems comprising a spring portion and a mount portion. The spring portion is a single piece molded structure that is preloaded against a precision machined surface on the mount portion during assembly. The preloaded spring feature provides good energy absorption characteristics to reduce the limit stop deflection during actuator contact. The precision machined surface on the mount portion accurately determines the limit stop position, thereby reducing tolerance requirements on the spring portion.
