Abstract
A PZT limiter in a microactuator type dual stage actuated (DSA) suspension limits travel of the PZT, particularly of the cantilevered end of the PZT and particularly during non-operational shock. The PZT limiter thus limits the stresses including bending placed on the PZT during the shock event and thus helps to prevent cracking of the PZT. Additionally, by limiting displacement of the PZT, the limiter improves the mechanic and electrical performance of the suspension during operation.
