Patent ID: 8897116

Claim:
A data storage device, comprising: a platter assembly comprising at least one platter that has at least one substantially planar surface; a graphene film positioned on at least a portion of a substantially planar surface of a platter of the platter assembly; a plurality of topographical features formed on the graphene film, wherein one or more topographical features are configured to represent one of at least two possible states, and wherein the graphene film is configured to store readable data in the at least two possible states using the topographical features; and at least one read module configured to read the readable data on the substantially planar surface of the platter by detecting each of the at least two states, at least one of which states is represented by the topographical features; and a movement assembly configured to move at least one of the at least one read module and the platter assembly with respect to the other; wherein at least two graphene films are positioned on the portion of the substantially planar surface of the platter of the platter assembly, wherein a plurality of topographical features is formed on each graphene film, wherein one or more topographical features are configured to represent one of at least two possible states, wherein each graphene film is configured to store in the at least two possible states using the topographical features, and wherein each of the at least two graphene films is separated from other graphene films by a spacer.
