High capacity digital data storage by transmission of radiant energy through arrays of small diameter holes
First Claim
1. A storage media for storage of data thereon, the storage media comprising:
- a first layer being substantially transparent to a radiant energy of predetermined optical wavelength used for reading the data;
a second layer formed on the first layer and being substantially opaque to the radiant energy, the second layer having a pattern comprising a plurality of holes, at least one of the holes having a largest dimension which is greater than the predetermined optical wavelength of the radiant energy, the data being stored as the presence or absence of a hole in the pattern; and
a third layer being disposed on the second layer and being substantially transparent to the radiant energy;
wherein the first, second, and third layers are configured such that said radiant energy passes through said storage media at substantially the same predetermined optical wavelength.
