Abstract
The invention provides an improved disk writing system capable of storing larger amounts of information than heretofore possible. The disk mechanism incorporates a dual function servomechanism which includes a voice coil motor for driving the read/write head over long distances relatively quickly, and a stepper motor for precisely positioning the read/write head once it is in the desired region.
