Optical storage tape surface. Confocal microscopy as a surface plot of a roll of plastic adhesive tape on which optical data has been written. Each hump is one bit of information. The information is written and read by a semiconductor laser. Focusing the laser onto specific points on the tape alters the refractive index (RI) of the tape at these points. Information such as images,sound and computer data can be stored on the tape. The laser has such a sharp focus that the tape does not have to be unwound.
