Abstract
A method and apparatus for reading and writing data from and to a data storage disc in a data storage device. The data storage disc includes a first disc surface and second disc surface for storing data. The data storage device includes an actuator assembly configured to selectively position a first transducer over the first disc surface and a second transducer over the second disc surface, wherein the first transducer is substantially identical to the second transducer. Furthermore, each transducer includes a read element and a write element, wherein the read element is offset from the write element by at least the width of one servo track.
