Latest Patents

One of his latest patents is a "Head positioning system with automatic gain control." This innovative system employs multiphase radial position error signals derived from position reference information on the disk to control the position of a transducing head. The system utilizes a variable gain amplifier to amplify signals from the transducing head before they are applied to a position error signal generating means. The gain of the amplifier is controlled in a gain control loop, which is derived by combining different phase position error signals. This design allows for gain control that is substantially independent of head width, thereby limiting variations in offtrack gain between heads.

Another significant patent is the "Magnetizable recording disk and disk file employing servo sector head." This invention involves a magnetizable recording disk divided into data and servo sectors. The servo sectors include position reference information comprising a circumferentially extending and radially repeated magnetization pattern. Each pattern consists of subsets of elements that provide different phases of radial position error signals, indicating displacement from a data track center line. This design enhances the linearity of the position error signal, improving the overall performance of the disk file.
