Title: The Innovative Contributions of James N. White

Introduction

James N. White is a notable inventor based in Kinross, GB. He has made significant contributions to the field of technology, particularly in the areas of computer disc drives and stepper motor control. With a total of 3 patents to his name, White's work has had a lasting impact on the efficiency and performance of electronic devices.

Latest Patents

One of White's latest patents is a ventilation system for computer disc drive hub assembly. This innovative system enhances disc file data storage capacity while improving disc-drive performance. The design incorporates a plurality of axially extending channels in the hub of the drive, along with a breather filter located in the housing wall of the chamber. This setup allows for effective air circulation, creating a high-pressure zone at the periphery of the discs and a low-pressure zone at the rotation axis. The result is a consistent air density adjacent to the disc surfaces, which optimizes the aerodynamic characteristics of the read/write heads.

Another significant patent by White is a method and apparatus for controlling a stepper motor. This invention minimizes oscillations during single steps and reduces the time taken for the stepper motor to move between tracks. The control mechanism utilizes a microprocessor-based circuit that drives the stepper motor according to predetermined programs. By managing the current applied to the motor and matching its torque-speed characteristics, White's invention enhances the overall performance of disk drives.
