ABSTRACT:
An electromagnetic radiation read mechanism for reading data stored optically upon an element having a surface and a plurality of tracks, which mechanism includes a source of electromagnetic radiation; an optical coupling system, which optical coupling system is disposed so as to receive radiation output by the source of electromagnetic radiation and spread it into a plane; a prism, which prism is constructed and disposed so as to receive the plane and redirect it to reflect off of the surface of the element, and which prism is further constructed and disposed so as to receive the reflected plane and to redirect it outward; a multi-element optical sensor, which sensor is disposed so as to receive the redirected reflected plane; and a decoder connected to the multi-element optical sensor so as to receive signals therefrom, which decoder allows parallel data reading of all of the tracks of the element simultaneously.
