Optical recording and reading method, optical recording and reading apparatus, optical recording medium, and method for producing an optical recording medium

摘要

An optical recording medium includes a recording and reading layer that is previously staked or formed afterward and has no concavo-convex pattern for tracking control, and a servo layer in which a concavo-convex pattern or a groove for tracking control is formed. Information can be recorded in the recording and reading layer while tracking is performed using the servo layer.
