Scanning tunneling microscope (STM) is used to investigate the optical disc. The areas with and without data stampers are all observed carefully. Three-dimensional images of the disc surface clearly demonstrate the period, depth of the grooves and the shape of data stampers. Some phenomena of STM imaging are also discussed.
