Latest Patents
One of his latest patents is for a disk drive in which magnetic head-to-disk capacitive coupling is minimized. This invention features a thin film magnetic data transducer that prevents capacitive coupling between the transducer and the disk of a disk drive system. The design maintains the magnetic circuit at the same potential as the disk, usually ground potential. This configuration prevents capacitive charging and current flow, which can lead to arcing or discharge noise. Additionally, noise from variable capacitive coupling during disk rotation is eliminated. The thin film magnetic transducer is created by depositing layers of insulating material, magnetic material, conducting material for a planar coil, and additional insulating and magnetic materials on a substrate. The planar coil consists of spiral turns, and the magnetic material layers encircle the coil, providing a magnetic gap between the pole tips outside the coil.
Another significant patent involves a method and apparatus for preventing parasitic electrical discharges in magnetic disk drives. This invention addresses the issue of parasitic capacitance that can lead to undesirable electrical discharges, potentially destroying data on the disk. The method includes applying a DC voltage to both the pole piece and the magnetic disk surface, which are kept at approximately equal voltages. This approach prevents the parasitic capacitance from charging to levels that could sustain electrical discharges.
