What Are Some Key Nanotechnology Innovations in Magnetic Data Storage?
Some of the key innovations include:
Spintronics: This technology exploits the intrinsic spin of electrons, along with their charge, to store data more efficiently. Heat-Assisted Magnetic Recording (HAMR): This technique uses heat to temporarily reduce the coercivity of the magnetic material, allowing for smaller and more stable data bits. Bit-Patterned Media (BPM): BPM uses nanolithography to create precise and isolated magnetic regions, significantly increasing data densities.
