STmicroelectronics Assigned Patent

STmicroelectronics S.r.l., Agrate Brianza, Italy, has been assigned a patent (11482248) developed by Giusti, Domenico, Caponago, Italy, and Ferrera, Marco, Concorezzo, Italy, for “read/write device for a hard-disk memory system, and corresponding manufacturing process.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Various embodiments of the present disclosure provide a read/write device for a hard-disk memory system. The read/write device includes a fixed structure, a membrane region including a first and a second membrane, which are constrained to the fixed structure, and a central portion, interposed between the first and second membranes, a first and a second piezoelectric actuator, mechanically coupled, respectively, to the first and second membranes, and a read/write head, which is fixed to the central portion of the membrane region. The first and second piezoelectric actuators can be controlled so as to cause corresponding deformations of the first and second membranes, said deformations of the first and second membranes causing corresponding movements of the read/write head with respect to the fixed structure.”

The patent application was filed on 2020-11-03 (17/088394).
