摘要:
A method is provided for making the storage media having data stored thereon. In one aspect of the making of storage media, a first layer is formed, where the first layer is substantially transparent to a predetermined first radiant energy used for reading the data. Next, a second layer is formed on the first layer, which is substantially opaque to the first radiant energy. Finally, a pattern is formed that comprises a plurality of holes in the second layer, where each of the holes have a largest dimension which is greater than a wavelength of the first radiant energy, and the data is stored as the presence or absence of a hole in the pattern.
