Abstract: A multi-layer rewriteable information storage medium includes a substrate which is laminated with a plurality of information recording stacks to form a single side double information recording layers and double sides four information recording layers or more to greatly increase storage capacity. When reading or writing signals, laser beams of the optical pick-up head pass through replicated groove/land surfaces for tracking use to reach the information recording stacks. Hence tracking signals do not weaken when the thickness of the information recording stacks changes, and groove/land dimensions also may be maintained unchanged when the thickness of the information recording stacks changes. The laser beams can penetrate the substrate of a thickness from 0.1 mm to 1.2 mm to reach the information recording stacks. The storage medium of the invention can be used on existing optical disk drivers for reading or writing operations without a lot of structural changes.
