US Patent Issued to STMicroelectronics International on June 17 for "Method of operating hard disk drives, corresponding control circuit, hard disk drive and processing device" (Italian Inventor)

ALEXANDRIA, Va., June 19 -- United States Patent no. 12,334,119, issued on June 17, was assigned to STMicroelectronics International N.V. (Geneva).

"Method of operating hard disk drives, corresponding control circuit, hard disk drive and processing device" was invented by Michele Boscolo Berto (Milan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A voice coil motor (VCM) in a hard disk drive is operated in a discontinuous mode with an alternation of on and off times. A drive current to the VCM is facilitated and countered with a variable voltage across the during the on-times and off-times. The intensity of the drive current is controlled as a function of a Back ElectroMotive Force (BEMF) of the VCM. A metho...
