Abstract
An optical pickup driving apparatus includes a carriage for a moving portion having an objective lens, a feeding motor having a moving coil for supporting the carriage, a magnet for producing a magnetic linked flux to the moving coil and a yoke member for controlling the magnetic path of the magnetic flux and movably supporting the moving coil, and a plurality of coils for minutely moving the objective lens vertically and horizontally in response to the magnet of the feeding motor. By reducing the weight of the moving portion mounted on the carriage, the feeding motor has a rapid response characteristic and therefore the optical pickup can search for information at high speed.
