Patents by Inventor Alexander Gennadievicj Soloviev

Alexander Gennadievicj Soloviev 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).

  • Magneto-optical head for information reading
    Patent number: 6288980
    Abstract: The invention relates to the devices for reading the information from magnetic carriers of recording, more detailed, to magneto-optical heads for reproducing the information. The technical result is substantiated in higher resolution, increase of ratio of useful signal to noise, simplification of construction and manufacturing process of the head, extending the service life. Magneto-optical head for reproducing of information consists of underlay 2 made of material characterized by high transparency in the spectral range of the source of the reading polarized light, for example, from a mono-crystalline gadolinium-gallium garnet. On the side of the underlay 2, that is turned towards magnetic medium 4 with the stored information, a magneto-optical transducer 3 is placed in form of a ferrite-garnet film, on the free side of which a reflective mirror layer 6 can be deposited.
    Type: Grant
    Filed: September 16, 1999
    Date of Patent: September 11, 2001
    Assignee: Garnetec Ltd.
    Inventors: Eugene Ivanovitch Il′Yashenko, Valentina Prokofiena Klin, Alexander Gennadievicj Soloviev
  • Magneto-optical thin-layer structure
    Patent number: 6143435
    Abstract: The invention relates to magneto-optical structures applicable in systems for optical processing of information, in sensors and converters of magnetic field. The technical result is comprised in increase of resolution and sensitivity, ensuring high value of Faraday rotation of polarized light and high speed of operation when pulses of external magnetic field are applied.
