Latest Patents

One of his latest patents is a method of making a recording head. This recording head is designed for use with magnetic recording media and features an improved structure achieved through a simplified manufacturing process. The use of inorganic electrically insulating materials within the recording head eliminates the need for a hard bake process typically required for organic insulators. In one embodiment, the write gap is first masked, allowing the coil to be deposited on the write gap. A larger area is then exposed within the mask, enabling insulation to be deposited over the coil. In another embodiment, the coil and associated insulation are deposited and then milled to create a tapered configuration. This innovative design allows the writing pole to be placed on a very flat surface, facilitating the manufacturing of plated or deposited films that correspond to narrow track widths.

Another significant patent by Bojko involves a lithography method that combines high gap resolution with high processing speed. In this method, an electron beam sensitive resist is applied to a substrate, followed by a photoresist. The undesired portions of the photoresist are removed through photolithography. An electron beam flood exposure or oxygen ashing is then used to eliminate those portions of the electron beam sensitive resist that are not protected by the photoresist. An optical flood is subsequently employed to remove the remaining photoresist. Finally, electron beam lithography is utilized to define narrow gaps within the remaining electron beam sensitive resist.
