Abstract
A data storage medium that includes several stacked layers. The stacked layers can be conducting, insulating, resistive, or capable of changing between two or more states or phases. Also, a data storage device that includes the data storage medium and an energy source that can form nanometer-scaled data bits in regions of the data storage medium. The data bits can include holes through some of the stacked layers or phase-changes in portions of the layers capable of changing between two or more states. Further, a method of using such a storage medium to store nanometer-scaled data bits.
Claims20
A data storage device comprising:
- a data storage medium that includes a first layer at a surface of the storage medium and a second layer between the first layer and a third layer;
- an energy source positioned proximate to the data storage medium;
- and
- a nanometer-scaled data bit extending through a portion of the second layer.
A method of storing data comprising:
- providing a data storage medium that includes a first layer at a surface of the storage medium and a second layer between the first layer and a third layer;
- writing a nanometer-scaled data bit in the second layer by bombarding the storage medium with a high-power-density beam;
- and
- reading the data bit by bombarding the data storage medium with a low-power-density beam.
