high data density

How is high data density achieved?

Several methods are employed to achieve high data density in nanotechnology:
1. Magnetic Storage: Techniques like Heat-Assisted Magnetic Recording (HAMR) and Microwave-Assisted Magnetic Recording (MAMR) use nanoscale magnetic particles to store data with higher density.
2. Optical Storage: Using plasmonic nanostructures and holography to increase the data density of optical discs.
3. DNA Data Storage: Encoding data into the sequence of nucleotides in DNA molecules, offering a theoretical maximum data density far exceeding current electronic storage methods.
4. Flash Memory: Advancements in 3D NAND technology where multiple layers of memory cells are stacked vertically to increase storage capacity.
