  • Attitude correction apparatus including opposing laser emitters
    Patent number: 8773653
    Abstract: An attitude correction apparatus includes a pair of opposing laser emitters that face each other. Each of the laser emitters includes a laser oscillator to generate a laser beam, a condenser lens to emit the laser beam toward the head suspension, and galvanomirrors to adjust the directivity of an optical axis of the laser beam from a standby state toward a spot on the head suspension. The condenser lens of each laser emitter is positioned so that the directivity of the optical axis of the laser beam in the standby state disagrees with an optical path that passes through the condenser lens and laser oscillator of the other laser emitter.
