Latest Patents

Vincent D Gravdahl holds a patent for "Thin film techniques for fabricating narrow track ferrite heads." This patent describes a process for producing a reactive ion-etched structure with height and width dimensions of the order of 25 microns or less on a ferrite substrate surface. The method involves forming a mask of positive water-saturated photoresist on the substrate, plating a metal from a group consisting of nickel and a nickel-iron alloy through the mask, and then removing the photoresist mask to leave a pattern in the plated metal. The exposed ferrite substrate surface is reactive ion etched with a power density of >1w/cm² and a bias voltage of <-100 volts.
