Breakthrough in HDD Technology Could Enable 120TB Storage Capacity

Researchers have demonstrated a new 3-D magnetic recording method, potentially revolutionizing data storage efficiency and capacity.

Research groups from NIMS, Seagate Technology, and Tohoku University have developed a 3-D magnetic recording method that could significantly increase HDD storage capacity.
The new technology allows for multi-level recording on HDDs, potentially enabling storage capacities of up to 120TB per drive.
The breakthrough involves using FePt grains and heat-assisted laser writing to achieve higher areal densities than current HDD technologies.
Data centers, which increasingly rely on HDDs for massive data storage, could see substantial energy savings and efficiency improvements with this technology.
The development is seen as a major step forward in meeting the growing demand for digital data storage, driven by advancements in AI, ML algorithms, and the digital transformation of industries.
