Werner Spaeth

Title: Werner Spaeth: Innovator in Optical Technology

Introduction

Werner Spaeth is a notable inventor based in Munich, Germany. He has made significant contributions to the field of optical technology, particularly in the development of innovative systems for disk drives. With a total of 2 patents, his work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is a lensless optical servo system for an optically assisted disk drive. This system utilizes an unfocused light source and patterned photodetectors. The unfocused light is reflected by markings on an LS-120 disk, and the reflected light carries the pattern of the markings to the photodetectors. The convolution of this light pattern and a mating geometric pattern on the photodetectors generates signals that represent the position of the track on the disk. In a preferred embodiment, a laser diode and three detectors are formed on the same silicon substrate. Sinusoidal metalization is applied to the detectors in the radial direction, with specific phase relationships between the metalizations of the detectors.
