Abstract
Gimbal designs are provided that minimize adverse dynamic performance of a HDD suspension, particularly subsequent to head-disk-interface (HDI) interactions. The improvement of operational performance can be seen in graphical representations of the vibrational modes of a gimbal mounted slider subsequent to such HDI interactions. Each gimbal design includes a ramp limiter formed as two separated arms connected by one or two transverse bars and a routing of conducting traces that relieves stress and minimally contacts these bars.
Claims6
A gimbal mounted slider comprising:
- a gimbal including a ramp limiter extending distally therefrom and formed as two substantially parallel and separated arms;
- a transverse bar formed between and connecting said arms, said bar being positioned approximately at a midpoint longitudinally along said arms;
- a slider mounting pad having a slider mounted thereon, said slider including solder ball connections formed on a distal surface thereof and said slider mounting pad extending proximally between a pair of separated outrigger elements that form the lateral periphery of said gimbal;
- a pair of conducting traces connected to said solder ball connections, each of said pair of conducting traces being routed transversely outward from said connections with a maximal length, while minimally overlapping with said transverse bar, to contact an outrigger and each of said pair of traces thence being routed in a proximal direction along a space between a lateral edge of said mounting pad and an inner edge of an adjacent outrigger;
- and
- a pair of trace support tabs, one tab extending transversely inward from the inner edge of each outrigger element, whereby each trace contacts a pad.
