<p>The disclosure relates to a positioning system for an optical disc drive which includes a mounting plate (10) for supporting a linear voice coil motor (18), and specifically for directly supporting the magnets (22) and frame (20) of the voice coil motor, the mounting plate further supporting a pair of guide rods (52, 54) which run from a point adjacent the voice coil motor to a point adjacent the optical data storage disc, the guide rods being used to support an optical transducer carriage (40) which positions an optical transducer relative to the track on the disc where information is to be accessed. The low profile voice coil motor includes a coil supporting structure (28) and voice coil (34) which is directly mounted to extended arms (42) on the optical transducer carriage, whereby the voice coil becomes an integral part of the transducer carriage, and is supported from the same guide rods which support the optical transducer carriage. With actuation of the coil in the voice coil motor, the voice coil is selectively positioned, thereby positioning the optical transducer carriage relative ot the optical disc for reading and writing information thereon.</p> |
