Title: Innovations of John F Bagby
Introduction
John F Bagby is a notable inventor based in Encinitas, California. He holds a total of four patents, showcasing his contributions to the field of technology and engineering. His work primarily focuses on advancements in recording technology, particularly involving ferrite heads.
Latest Patents
One of his latest patents is titled "Quadruplex recordings with ferrite heads resembling quadruplex." This invention addresses the need for refurbishing prior art quadruplex head assemblies equipped with metal heads. The concept involves mounting corrective compensation circuits to refurbished quadruplex head assemblies, allowing recordings made with ferrite heads to be interchangeable with those made by metal heads on the same recorder without requiring adjustments. The compensation circuits are designed to self-disable during signal playback, enhancing the functionality of the recording process.
Another significant patent is the "Method of manufacturing a single-track video ferrite record/reproduce." This method involves bonding two magnetic ferrite pieces with longitudinal channels, creating a window for precise slotting. The resulting slots are designed to receive gap-protecting compatible ceramic support material, which wears slightly faster than the ferrite surfaces. This innovative approach allows for the creation of a ceramic-ferrite-ceramic transducer sandwich, which can be further processed for use in magnetic recording and reproduction heads.
