ABSTRACT:
A recording system for representing digital information in the form of marks and the absence of marks at a plurality of locations, each mark being formed in response to energy delivered by an optical beam; the device includes a material configured in a form to receive the beam at selected locations for forming the marks, the material being characterized by undergoing pyrolysis to form the marks at the selected locations in response to the energy.
