MULTI-BIT CELLULAR REFLECTIVITY MODULATION FOR OPTICAL MEDIA An optical storage device, comprising a disk having a recording surface for reflecting laser light incident thereon, and a plurality of cells representing stored data. Each of the cells is characterized by one of 2N predetermined levels of effective reflectivity to the incident laser light, where N>1 and wherein N represents the number of bits stored per cell.
