Latest Patents

Joseph M Humel holds a patent for a disk drive servo control system. This invention involves a dedicated servo system where a reference track is written in the outer guardband of the servo surface and each of the data surfaces. The system obtains supplemental position error signal (PES) values from the difference between servo and data surface samples at various locations around the disk. These values are stored for access during read/write operations. The supplemental PES values are combined with dedicated surface PES values to create a composite PES that accurately follows the data track centerline of the disk surface being addressed. Additionally, the supplemental PES values are periodically updated to ensure precision. The invention also incorporates a correction technique that is tolerant of tangential skew, which can affect track readability.
