Abstract
A method of storing data in a storage device having a probe to form perturbations in a storage medium of the storage device includes receiving input write data bits and encoding the input write data bits to form coded write data bits. Perturbations are formed in the storage medium by contacting a probe to the storage medium, the perturbations corresponding to the coded write data bits, wherein the coded write data bits provide a generally uniform distribution of the perturbations on the storage medium.
Claims22
A storage device comprising:
- a storage medium;
- a probe to form perturbations in the storage medium, wherein the probe comprises a nanotechnology probe;
- an encoder to receive write data and to encode the write data according to an algorithm to reduce variations in density of perturbations on the storage medium,
- wherein the probe is adapted to form perturbations in the storage medium corresponding to data bits of the encoded write data.
A method of storing data in a storage device having a probe to form perturbations in a storage medium of the storage device, comprising:
- receiving input write data bits;
- encoding the input write data bits to form coded write data bits;
- and
- forming perturbations in the storage medium by contacting a probe to the storage medium, the perturbations corresponding to the coded write data bits, wherein the coded write data bits provide a generally uniform distribution of the perturbations on the storage medium.
A system comprising:
- a processor;
- and
- a storage device coupled to the processor, the storage device comprising:
- a storage medium;
- a probe to contact the storage medium to form dents in the storage medium;
- an encoder to receive write data and to encode the write data according to a predetermined algorithm,
- wherein the probe is adapted to form dents in the storage medium corresponding to data bits of the encoded write data to the storage medium
