ABSTRACT OF THE DISCLOSURE The present invention comprises an improved position- ing system for an optical disc drive which includes a mounting plate for supporting a linear voice coil motor, and specifically for directly supporting the magnets and frame of the voice coil motor, the mounting plate further supporting a pair of guide rods 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 which positions an optical transducer relative to the track on the disc where information is to be accessed. The low profile voice coil motor of this invention includes a coil supporting struc- ture and voice coil which is directly mounted to extended arms 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 selec- tively positioned, thereby positioning the optical trans- ducer carriage relative to the optical disc for reading and writing information thereon.
