Title: Vincent Marrello: Innovator in Data Storage Technology
Introduction
Vincent Marrello is a prominent inventor based in Morgan Hill, CA (US). He has made significant contributions to the field of data storage technology, holding a total of 3 patents. His innovative work focuses on enhancing the efficiency and effectiveness of data recording systems.
Latest Patents
One of Marrello's latest patents is a servo-writing system designed for use in data recording disk drives. This non-invasive system measures actuator position and generates a reference clock using semiconductor lasers. It features internal position references provided by reflective diffraction gratings affixed to the actuator arm and spindle hub. The system employs wavefront reconstruction optics to correct for aberrations in the gratings, while optical sensors detect differential changes in the diffraction patterns, eliminating sensitivity to frequency drift. The decode electronics convert the optical sensor data into actuator position measurements, and the control electronics drive the voice coil motor within the disk drive to position the write transducer for recording servo information.
Another notable patent involves a process for optically storing information using materials that can switch between amorphous and crystalline states. This optical storage system utilizes a film with a crystallization temperature between 100°C and 400°C. The material is heated with a circular laser beam to create spots that can be quenched at different rates to produce either the amorphous or crystalline state.
