  • Optical system drive apparatus for an optical recording/reproducing apparatus
    Patent number: 5228017
    Abstract: An optical system for an optical recording and/or reproducing apparatus that irradiates laser light emitted from a light emitting diode (8) to an opto-magnetic disk (2) via a relay prism (11) and an objective lens (12) and irradiates light reflected by said opto-magnetic disk to a light-receiving diode (15 A,B), and which has a first moving portion (22) that holds the objective lens, a second moving portion (33) that holds the relay prism, a connection mechanism connecting the first moving portion and the second moving portion, a focus moving device (21) to move said first moving portion in the direction of focus, and a tracking feed moving device (27) to move the first and second moving portions in the direction of tracking feed.

  • Compact optical disc recording/reproducing system
    Patent number: 5220543
    Abstract: An optical recording/reproducing system for optically recording and reproducing an information signal on and from an optical disc (31) to be recorded with a plurality of track turns includes a light source (52); an optical head (45b) carrying an objective lens (62) for directing a light beam from the light source (52) to one of the track turns, and a tracking servo actuator for displacing the light beam within a movable range to perform both track feed and tracking servo operations for one of the track turns; the optical head (45b) being stationary with respect to the optical disc (31) while performing the track feed and tracking save operations by displacing the light beam in a radial direction of the optical disc; and a recording area on the optical disc having a radial distance equal to or smaller than the movable range of the tracking servo actuator.
