Title: Wayne P. Schaefer: Innovator in Magnetic Tape Technology

Introduction

Wayne P. Schaefer is a prominent inventor based in North St. Paul, MN, recognized for his contributions to magnetic tape technology. With a total of three patents to his name, he has made significant advancements that enhance the efficiency and efficacy of magnetic tape media.

Latest Patents

Schaefer's groundbreaking patents include innovative methods related to bias techniques for magnetic tape media. His disclosures detail a method for creating a remnant magnetization on a magnetic tape medium. Initially, the magnetic tape is substantially demagnetized, typically through an erasure unit equipped with multiple magnetic elements of alternating polarity. After this process, the erased magnetic tape is passed by a bias magnet that generates a remnant magnetization. This magnetized tape then advances through a servo write head, which imprints servo patterns onto the remnant magnetized surface. The configuration allows the bias magnet to be either integrated within the erasure unit or in a separate bias unit, with an adjustable distance between the magnet and the tape path. This level of precision ensures that the remnant magnetization can exceed 20 percent, significantly reducing defects in the servo patterns recorded on the magnetic tape.
