ABSTRACT:
A drive mechanism in a data storage apparatus for positioning and rotating a two-sided data storage medium. The drive mechanism includes at least one repeller adjacent each side of the data storage medium repelling at least one control element on the data storage medium thereby positioning the data storage medium. The drive mechanism also includes a plurality of driver elements located adjacent the data storage medium. Each of the driver elements is capable of selectably attracting or repelling the at least one control element on the data storage medium thereby causing the data storage medium to rotate while the data storage medium is positioned by the at least one repeller. Also disclosed is a method of positioning and rotating a two-sided data storage medium by repelling at least one control element on the data storage medium thereby positioning the storage medium substantially in a pre-determined position for rotating the data storage medium, and selectably attracting and repelling the at least one control element on the data storage medium thereby causing the data storage medium to rotate while the data storage medium is substantially maintained in the pre-determined position.
