METHOD FOR PRODUCING MEDIUM ON WHICH INFORMATION IS RECORDED BY PIT PATTERN

摘要

A method by which depressions and projections (pit pattern) can be formed directly and easily in a substrate made of inorganic material is provided. A method for forming a medium on which information is recorded in a pit pattern comprises the steps of: forming a recording material layer (21) over a substrate (11) made of inorganic material wherein the recording material layer is of a thermally deformable heat mode recording material; forming a plurality of holes 15 by application of condensed light to the recording material layer (21); and forming a plurality of pits (16) in the substrate wherein the plurality of pits corresponding to the plurality of holes (15) are etched by using as a mask the recording material layer (21) in which the plurality of holes are formed.
