Patents by Inventor Surya Narayan Pattanaik

Surya Narayan Pattanaik 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).

  • Patent number: 8035988
    Abstract: The present invention provides methods and systems for repeatably creating and severing a short circuit to protect an electronic component from ESD. A short circuit may be formed between read sensor pads of a read sensor by depositing a shorting material on a magnetic head using a Laser Induced Forward Transfer (LIFT) process. The short circuit may be unshorted using a laser scan configured to sever the shorting material. In one embodiment, a shorting station may be provided to prevent spreading of the shorting material to undesired areas of the electronic component.
    Type: Grant

  • Patent number: 7345853
    Abstract: A device according to one embodiment includes an electronic component such as an MR sensor, a pair of leads operatively coupled to the electronic component, and shorting material between the leads, the shorting material having been applied by a laser deposition process, the shorting material having been severed. A magnetic storage system according to another embodiment includes magnetic media; and at least one head for reading from and writing to the magnetic media, each head having: a sensor; and a writer coupled to the sensor. The system also includes a pair of pads or leads operatively coupled to the head; shorting material between the leads, the shorting material having been applied by a laser deposition process, the shorting material having been severed; a slider for supporting the head; and a control unit coupled to the head for controlling operation of the head.

  • Patent number: 7236334
    Abstract: A method for shorting, unshorting, and reshorting an electronic component such as an MR sensor provides a repeatable ESD protection scheme. A conductive line of an electrically conductive first shorting material is created between electrical leads operatively coupled to an electronic component for creating a short therebetween. The short is severed using a laser. The short is recreated by applying a second shorting material, which may or may not be the same as the first shorting material.
