  • Optical head in a device for recording and reading a data carrier
    Patent number: 4744071
    Abstract: The optical head in the recording-reading device of a data carrier comprises a semiconductor laser source. A lens makes it possible to focus the beam from this source on to the data carrier via a reflecting or deviating mirror. According to the invention the rotation axis of this mirror is in the plane of the entrance pupil and of the focus of the focusing lens.
    Type: Grant
    Filed: January 21, 1986
    Date of Patent: May 10, 1988
    Assignee: Thomson-CSF
    Inventors: Claude Bricot, Michel Chaboche, Patrick Volleau, Dominique Leterme, Jean-Pierre Le Merer

  • Electrically controlled optical deflector
    Patent number: 4460252
    Abstract: This invention concerns electrically controlled optical deflectors, and more specifically an optical deflector comprising a mirror forming part of an assembly which cam move in relation to a fixed base, the pivotal movements of this assembly being controlled by an electrodynamic motor with a winding through which a variable current passes, and which is situated inside a predetermined magnetic field, the mechanical connection between the movable assembly and the fixed base being provided by a prismatic elastic component.This invention applies in particular to the construction of reading heads to direct an optical beam on to a videodisc track.
