The present invention includes an optical disc whose informational units
each contain a raised pad designed to reflect laser light at a compound
angle which is 45 degrees from the disc surface and at one of 1024 preset
angles between 0 and 360 degrees (with 0 degrees being oriented radially
towards the disc center). Light reflected from the information units
intersects with a ring of light detecting receptors arranged
circumferentially around the laser/light source. When individual
receptors are struck by reflected laser light: a signal is sent to a
processor. This processor determines the order in which the receptors are
stuck and outputs integers. Each integer corresponds to the receptor that
was struck and this data, when streamed sequentially, reproduces the data
stored on the optical disc.
