ABSTRACT:
A laser-writable information storage blank comprises a substantially planar disk made of a material which is susceptible to modification by impingement of laser radiation. The blank medium includes a metallic track pattern, preferably in the form of a spiral pattern. The track pattern provides two reference edges from which exact distances may be determined for writing and reading binary information stored between adjacent track portions.
