Title: Fred W Spong: Innovator in Magneto-Optic Technology

Introduction

Fred W Spong is a notable inventor based in Boulder, CO (US), recognized for his contributions to magneto-optic technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

Among his latest patents is the "Magneto-optic recording structure and method." This invention involves a magnetic magneto-optic recording structure where a magneto-optic active layer is strategically positioned within the fringing magnetic field of a magnetic recording medium. The structure is designed to be disk-shaped, allowing the magneto-optic layer to be irradiated by a continuous wave laser beam. This process locally reduces the coercivity of the magneto-optic layer, enabling it to become magnetized in alignment with the fringing magnetic fields created by previously recorded information. The recorded information can then be read out using a laser beam of lesser power, utilizing the Kerr effect.

Another significant patent is the "Optical storage structure," which describes an information storage device that combines a radiation recording structure. This device includes a substrate, a recording layer, and a thin electrically conductive over-layer on the outer surface of the recording structure. Additionally, it features a neutralizing means to maintain the over-layer at a neutral electrical potential.
