Title: Hemant K Mody: Innovator in Magnetic Technologies
Introduction
Hemant K Mody is a distinguished inventor based in Rochester, NY (US). He holds a total of 8 patents that showcase his innovative contributions to the field of magnetic technologies. His work has significantly impacted the design and functionality of various devices, particularly in the realm of data storage and motor control.
Latest Patents
One of Mody's latest patents is titled "Shorted turn for moving coil motors." This invention involves a linear motor designed to control the radial position of a write/read transducer relative to a rotating data storage disk. The motor features an elongated tubular-shaped permanent magnet that surrounds a pole piece made of highly permeable material. A selectively energizable coil is arranged between the magnet and pole piece, allowing for axial movement in response to an applied current. The invention includes shorting rings made of high conductivity, low permeability material, which reduce the rise time of current applied to the coil without significantly affecting the magnetic flux in the air gap.
Another notable patent is the "Method and device for erasing and writing on magnetic recording media." This invention describes a method for erasing and writing on magnetic particle oriented media by moving a magnetic field at a finite angle. The magnetic stencil used in this process allows for simultaneous creation of alternating fields, enabling information to be written over previously recorded data without requiring a separate erasure step.
