ABSTRACT:
A high density data storage system includes a rotatable storage medium mounted to rotate about a drive axis, the storage medium having formed thereon a surface topography defining machine readable information. The storage system further includes a high resolution contact sensor having a cantilever arm and a stylus mounted at one end of the cantilever arm. The stylus is positionable to engage the storage medium and follow the surface topography when the storage medium is rotated. A detector system provides an output signal representing cantilever deflection caused by changes in the surface topography of the storage medium.
