Breakthrough in Data Storage: Diamond's Record Data Density

Scientists at the City University of New York (CUNY) have achieved a groundbreaking advancement in data storage technology by utilizing diamond, enabling record data density down to a single atom.

Overcoming Diffraction Limits with Diamond

Optical memory technologies often face limitations in writing fine data due to laser beam diffraction. CUNY researchers discovered a method to surpass these limitations using diamond as a storage medium.

Controlling Color Centers for Precision

Researchers control the electrical charge of color centers using a narrow-band laser and cryogenic conditions. This precise control allows for writing and reading data at a finer level than was previously achievable.

Multicolor Approach for Higher Data Density

Different wavelengths of light are used to write data to color centers closer together than the diffraction limit allows. This approach enables three times more data storage in one region, alternating between different colors.

Achieving 25 GB per Square Inch

In tests, the researchers successfully imprinted 12 different images at different frequencies in the same spot. This resulted in a remarkable data density of 25 GB per square inch, equivalent to a standard single-layer Blu-Ray disc

Reversible Data Storage: Write, Erase, Rewrite

The technique is reversible, allowing for the writing, erasing, and rewriting of data as needed. This flexibility enhances the practical applications of the breakthrough.

Expanding Beyond Diamond

Researchers believe that with further development, the breakthrough could be applied to other materials. Potential to operate at room temperature, eliminating the need for cryogenic conditions.
