1. An optical disc containing information units arranged spirally from the disc center to the outer radial edge of the disc which are uniform in shape and size, with each unit containing a reflective pad which is raised from the disc surface, rather than sunken into the disc as a pit, designed to reflect incident light away from the surface of the disc in the shape of a straight line at an angle of 45 degrees from the disc surface and at one of 1024 preset angles between 0 degrees and 360 degrees from the center of the light source with 0 degrees oriented radially towards the center of the disc.
