Optical parts driving mechanism in optical information reader

摘要

A new optical parts driving mechanism in an optical information reader is provided. In general, the reader reads information contained in an information recording medium such as a disc having a driving mechanism axially extending in the center thereof. The optical parts driving mechanism has a lens holder adapted to travel parallel to the disc and carrying an objective at a portion substantially closest to said disc driving mechanism. Said driving mechanism further has focus direction drive and track direction drive. The track direction drive is mounted to said lens holder on an opposite side thereof with respect to said disc driving mechanism.
