  • Patent number: 10074390
    Abstract: A PZT microactuator such as for a hard disk drive has a restraining layer bonded on its side that is opposite the side on which the PZT is mounted. The restraining layer comprises a stiff and resilient material such as stainless steel. The restraining layer can cover most or all of the top of the PZT, with an electrical connection being made to the PZT where it is not covered by the restraining layer. The restraining layer reduces bending of the PZT as mounted and hence increases effective stroke length, or reverses the sign of the bending which increases the effective stroke length of the PZT even further. The restraining layer can be one or more active layers of PZT material that act in the opposite direction as the main PZT layer. The restraining layer(s) may be thinner than the main PZT layer.

  • Patent number: 10068595
    Abstract: A dual stage actuated suspension has a first piezoelectric microactuator on the trace gimbal assembly (TGA), and a pseudo feature located laterally opposite the microactuator. The pseudo feature is formed integrally with the TGA from at least one of the base metal layer, the insulative layer, and the conductive layer that make up the TGA. The pseudo feature helps to balance the suspension. The suspension can optionally have a second microactuator located proximal of the first microactuator in order to perform coarser positioning than the first microactuator, such that the suspension is a tri-stage actuated suspension.

  • Publication number: 20180182418
    Abstract: In a gimbal dual stage actuated (GSA) suspension for a disk drive, a viscoelastic damper is disposed between and adhered to the suspension's PZT microactuator and the flexure trace gimbal. The damper is dispensed in fluid form onto the trace gimbal during assembly of the suspension, the PZT is placed onto the damper, and the damper is then hardened leaving it adhered to both the PZT and the trace gimbal. The damper reduces peaks in the frequency response of the PZT actuation, thus allowing higher bandwidth of the servo control loop and increasing the effective read and write speeds for the suspension.
