Title: Shri Hari Narayan: Innovator in Data Storage Technology

Introduction

Shri Hari Narayan is a notable inventor based in Minneapolis, MN (US), recognized for his contributions to data storage technology. With a total of 6 patents to his name, he has made significant advancements in the field, particularly in the design and functionality of head suspensions for data storage devices.

Latest Patents

One of his latest patents is titled "Head suspension with vibration damping for a data storage device." This invention focuses on an apparatus, method, and combination for dissipating vibration from a head suspension of a data storage device. The combination includes a rotating disc in a data exchange relationship with a read/write head supported by a head suspension formed by a specific method. The method involves forming a mounting region and a load beam region adjacent to a bend region, removing material from the bend region to create an aperture, a strut, an isolation aperture, and a damping material support structure. The apparatus features a bend region adjacent to both the mounting region and the load beam region, with damping material attached to the strut and the damping material support structure. The load beam region includes a rigid portion that supports a flexure upon which a read/write head is attached.

Another significant patent is "Adhesive control features for disc drive head suspension and flex circuit interconnect." This invention provides a system, method, and apparatus for controlling the coverage of an adhesive bond area between a suspension and a flex circuit interconnect. The etching process creates a bonding area that prevents bonding of the flex circuit interconnect to the suspension in a tail and side region, allowing movement between the flex circuit and suspension. This movement dampens a first torsion resonance mode, leading to better control of the bonding area and reducing the variation in the roll stiffness of the suspension, thereby minimizing fly height variation.
