Introduction

Muhammad A Hawwa is a notable inventor based in Simi Valley, California. He has made significant contributions to the field of disc drive technology, holding a total of 6 patents. His work primarily focuses on enhancing the performance and efficiency of rigid disc drives.

Latest Patents

One of his latest patents is the "Piezoelectric head loading and unloading device for rigid disc drives." This innovative system is designed to load a transducing head to a flying elevation close to the rotating surface of a disc. It utilizes a piezoelectric device that can be selectively expanded and contracted to control the height of the head on a flexure spring from the disc surface. The system also includes control circuitry that generates electrical control signals to manage the piezoelectric device's operation based on the disc's characteristics.

Another significant patent is the "Method of making an actuator arm integrated piezoelectric microactuator." This invention involves a system for positioning a transducing head over a selected track of a rotatable disc. It features a rotatable actuator arm, a head suspension mechanism, and a slider carrying the transducing head. A low-resolution motor facilitates coarse movement, while an embedded piezoelectric element allows for fine positioning of the head. Control circuitry is employed to distribute electrical signals to both the motor and the piezoelectric element for precise control.
