Title: Innovations of Jayadev P Patel

Introduction

Jayadev P Patel is an accomplished inventor based in San Jose, California. He has made significant contributions to the field of calibration technology, particularly in the design of calibration disks used in glide head testing.

Latest Patents

One of his notable patents is for a calibration disk having discrete bands of calibration bumps. This innovative disk is designed to calibrate the fly height of a head, featuring spaced circumferential bands that extend concentrically from the outer diameter to near the inner diameter of the disk. Each band contains radial and circumferentially spaced asperity emulating bumps, which are crucial for producing a constant and continuous output signal from a glide head when it operates below the maximum height of the bumps. The uniform height of the bumps within individual bands, along with the differing average heights across bands, helps to mitigate errors caused by disk waviness, runout, and contamination. This design allows for glide head calibration without the need for independent fly height measurements, thus eliminating errors and delays associated with traditional testing methods.
