Title: The Innovations of James W. Hargarten
Introduction
James W. Hargarten, an inventive mind based in Lafayette, Colorado, has made significant contributions to the field of data storage technology. With an impressive portfolio of 8 patents, Hargarten has demonstrated expertise in developing advanced disk drive systems that enhance data reliability and efficiency.
Latest Patents
Among Hargarten's most recent inventions are two notable patents focused on improving the functionality of disk drives. The first, titled "Disk Drive During Self-Servo Writing," outlines a process wherein the disk drive self-writes on a storage disk. This method involves using servo bursts that are self-written along a track with the help of a transducer. A position error signal (PES) is employed to assess repeatable runout (RRO) for the servo bursts, with an embedded runout correction (ERC) value being calculated and stored in a corresponding servo sector. This innovation significantly improves the reliability of data storage processes.
The second patent, "Method to Correct Radial Misposition of Data Tracks Using Stitched Correction Fields," addresses the issue of radial mispositioning of data tracks. This method entails measuring the radial misposition of tracks and repositioning them at regular intervals. The written in runout (WRO) found in servo bursts is utilized to verify track spacing and proper squeeze among adjacent tracks. By incorporating a squeeze correction term into the servo wedges, the disk drive can effectively position the head at the right track radius, ensuring accurate data storage.
