Title: Duane C Meulners: Innovator in Magnetic Disk Technology
Introduction
Duane C Meulners is a notable inventor based in San Jose, California. He has made significant contributions to the field of magnetic disk storage systems, holding a total of 2 patents. His work has advanced the technology used in floppy disk drives and diagnostic recording systems.
Latest Patents
One of Meulners' latest patents is the "Fine positioning apparatus for floppy disk drive." This invention features a positioning system that utilizes a first and second lead screw connected to their respective stepper motors. These components are mechanically linked by a lever arm that combines their motions. The first stepper motor operates under an open loop control circuit, while the second is governed by a closed loop circuit that reads servo information from the magnetic disk. This innovative design allows the head to be constantly repositioned to follow track eccentricities, enabling accurate reading of closely spaced tracks on non-rigid disks.
Another significant patent is the "Diagnostic recording." This invention provides a diagnostic recording that can be read by a computer system, allowing users without specialized knowledge, software, or equipment to check, isolate, and identify hardware malfunctions. The track features magnetic signals recorded within a normal track space, with a pair of void spaces of equal width on either side. These void spaces extend parallel to the track and are designed with specific widths for diagnostic purposes.
