  • Dual shield vertical magneto-optical read head
    Patent number: 6771567
    Abstract: A magneto-optical read head for detecting magnetic transitions representing data stored in a magnetic recording medium as a sense layer having an optical property that is magnetic field-dependent, two magnetic shield layers respectively disposed on opposite sides of the sense layer and allowing magnetic flux from substantially only one of the magnetic transitions to interact with the sense layer at a time, with one of the magnetic shield layers being transparent at a wavelength allowing light at that wavelength to enter into and exit from the sense layer.
    Type: Grant
    Filed: November 6, 2001
    Date of Patent: August 3, 2004
    Assignee: O-Mass AS
    Inventors: Jean-Pierre Nozieres, Sebastien Ferrand, Yannick Maral, Jean-Christophe Toussaint, Jørn Raastad
