Abstract

The present disclosure provides systems and methods associated with data storage using atomic films, such as graphene, boron nitride, or silicene. A platter assembly may include at least one platter that has one or more substantially planar surfaces. One or more layers of a monolayer atomic film, such as graphene, may be positioned on a planar surface. Data may be stored on the atomic film using one or more vacancies, dopants, defects, and/or functionalized groups (presence or lack thereof) to represent one of a plurality of states in a multi-state data representation model, such as a binary, a ternary, or another base N data storage model. A read module may detect the vacancies, dopants, and/or functionalized groups (or a topographical feature resulting therefrom) to read the data stored on the atomic film.

Claims30

Dependent claims

A data storage device, comprising:

a platter assembly comprising at least one platter that has at least one substantially planar surface;
a monolayer atomic film positioned on at least a portion of a substantially planar surface of a platter of the platter assembly, wherein the monolayer atomic film comprises a lattice structure;
and
a plurality of functional groups attached via functionalization to the monolayer atomic film,
such that each of the functional groups is functionalized to the lattice structure,
wherein one or more functional groups are configured to represent one of at least two possible states, and
wherein the monolayer atomic film is configured to store readable data in the at least two possible states using the attached functional groups;
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 functional groups;
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 the monolayer atomic film comprises a hexagonal boron nitride (h-BN) film, and
wherein a first type of functional group is configured to represent a first state of three possible states, a second type of functional group is configured to represent a second state of three possible states, and wherein the readable data is configured to be stored on the hexagonal boron nitride film as ternary (base 3) data values.
