1. A method of writing data to a machine-readable medium, the method comprising:
receiving a numerical value comprising a set of digit/position pairs, the set comprising at least a first subset of digit/position pairs, and a second subset of digit/position pairs;
receiving an association between at least the first and the second subsets of digit/position pairs and the set of digit/position pairs;
receiving a one-to-one association between at least the first subset of digit/position pairs and a first subset of molecules, and the second subset of digit/position pairs and a second subset of molecules, the first and the second subsets of molecules each selected from a set of unambiguously identifiable molecules, wherein each molecule in the first subset is identifiable by a first physical property, and each molecule in the second subset is identifiable by a second physical property, different from the first physical property;
determining a collection of molecules corresponding to the numerical value, wherein determining the collection comprises:
determining at least a first subcollection of molecules corresponding to the first subset of digit/position pairs, and a second subcollection of molecules corresponding the second subset of digit/position pairs, and
including at least the first and the second subcollections into the collection of molecules; and
physically associating the molecules of the collection with a substrate of the machine-readable medium at an addressable location thereon.
