James Richard Peterson 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).

  • Ion mill shutter system
    Patent number: 7144484
    Abstract: A method for producing magneto resistive heads includes the steps of positioning at least two magneto resistive elements in spaced relation to one another and placing the at least two magneto resistive elements in an ion milling environment where material is removed nonselectively from items in the environment. A property of at least two of the plurality of magneto resistive elements is monitored. In response to monitoring, one of the at least two magneto resistive elements is dynamically covered to prevent additional removal of material from the covered magneto resistive element.
    Type: Grant

  • Wafer fabrication for thermal pole tip expansion/recession compensation
    Patent number: 6731463
    Abstract: The slider and method of the present invention relate to a slider for a disc drive. The slider includes a substrate having a cavity and a filler within the cavity. The slider further includes a transducer that is positioned near the filler. The design facilitates controlling the relative thermal expansion between the transducer and substrate of the slider that is near the transducer. Compensating for the thermal expansion of the transducer provides a more consistent fly height of the slider during operation of the disc drive. In addition, the design adjusts the air-bearing surface of the slider such that the transducer does not extend below the rest of the slider as the transducer expands.

  • Radiation-curable poly(.alpha.-olefin) adhesives
    Patent number: 5859088
    Abstract: The invention relates to adhesive compositions comprising polymers comprising C.sub.6 to C.sub.12 saturated .alpha.-olefin monomers and C.sub.2 to C.sub.5 .alpha.-olefin monomers and an effective amount of photoactive crosslinking agent to crosslink composition upon radiation from a source of actinic radiation.
