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, the first layer being substantially transparent to a predetermined radiant energy used for reading the data; and
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 a wavelength of the radiant energy, the data being stored as the presence or absence of a hole in the pattern.
