Patents by Inventor Steven Paul Bozeman

Steven Paul Bozeman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Wire-assisted magnetic write device with low power consumption
    Patent number: 8339736
    Abstract: A magnetic device includes a write element having a write element tip and a conductive coil that carries current to induce a first field in the write element. A first conductor is proximate a leading edge of the write pole tip for carrying current to generate a second field that augments the first field.

  • Virtual front shield writer
    Patent number: 7876531
    Abstract: A magnetic writer includes a first write element and a second write element. The first write element produces a first field when a first current is passed through a first coil. The second write element, which is disposed relative to the first write element, produces a second field when a second current is passed through a second coil such that the second field at least partially opposes the first field.

  • Recording head for reducing side track erasure
    Patent number: 7684150
    Abstract: The present invention relates to a head having an air bearing surface for confronting the surface of a storage medium. The head includes a first pole that is spaced apart from a second pole. At least one non-magnetic spacer is positioned between the first pole and the second pole such that the first pole is magnetically decoupled from the second pole. In a further aspect, one or both of the first pole and the second pole can be elliptical in shape.

  • High sensitivity spin valve stacks using oxygen in spacer layer deposition
    Publication number: 20020101689
    Abstract: The invention includes methods of manufacturing improved spin valve sensors and the resulting sensors. The method includes the step of depositing a spacer layer in an environment containing oxygen. Preferably, the spacer layer is deposited in an environment containing argon and from about 0.5 to 25,000 ppm oxygen. Spin valve sensors of the invention have a spacer layer containing a non-magnetic electrically conductive material and oxygen. Spin valve sensors of the invention can be dual spin valves, bottom pinned spin valves or top pinned spin valves.

  • Spin valve films with improved cap layers
    Publication number: 20020024778
    Abstract: The invention includes spin valve sensors. The spin valve sensors of the invention can be dual spin valves, bottom pinned spin valves, or top pinned spin valves. Spin valve sensor in accordance with the invention include a cap layer of tantalum nitride and a free layer. Cap layers of the invention include both monolayers and bilayers. Monolayer cap layers are tantalum nitride, and bilayer cap layers are a first layer of tantalum nitride with a layer of copper, ruthenium, gold, or silver thereon.
