Seagate Unveils Multi-Level HAMR Tech for HDDs, Eyes 240TB Capacities

Seagate's breakthrough in hard drive technology could revolutionize storage capacities, aiming for up to 240TB per drive within the next decade.

Seagate Technology, alongside NIMS and Tohoku University, demonstrates a multi-level heat-assisted magnetic recording (HAMR) technology, potentially doubling current data storage capacities.
The new HAMR tech involves stacking data recording layers and utilizing dual nanogranular films, enabling storage capacities of up to 240TB per drive.
This innovation comes as a response to the growing need for larger storage solutions, particularly for data-heavy applications like AI and large-scale industrial storage.
While the technology has been proven in lab conditions, its practical application faces challenges, including the need for new read/write head designs and the high initial costs.
The potential for multi-level recording could lead to hard drives with capacities 10 times larger than Seagate's current largest offerings, marking a significant leap in the storage industry.
