Can Multi-Level HDDs Reach 120TB with HAMR Tech?

In a world increasingly dominated by big data, HDD manufacturers are pushing the boundaries of storage technology to keep pace with the exponential growth of data. The quest to substantially boost the storage capacity of hard disk drives (HDDs) may soon reach an extraordinary milestone: the 120TB drive. This ambitious goal hinges on the innovative use of Heat-assisted Magnetic Recording (HAMR) technology, combined with a novel multi-layered stacking methodology.

HAMR technology employs a precise laser to heat the recording layer, which greatly improves the recording density. Traditional HDDs have hit a physical plateau; however, by integrating HAMR with a multi-tiered data storage approach, groundbreaking storage densities may become feasible. This cutting-edge strategy uses dual nanogranular films separated by a breaking layer to enable multiple layers within a single HDD that can be independently accessed and manipulated.

The Path to a 120TB Future

Seagate Technology’s research into multi-level recording is paving the way for a potential breakthrough in HDD capacities, eyeing an astounding 120TB storage potential. This technique relies on manipulating Curie temperatures unique to each data layer to modulate their magnetic properties, thus enhancing data isolation and stability. This innovation could be revolutionary, especially for data-intensive sectors like artificial intelligence and the development of large language models, promising a seismic shift in storage solutions.

While the concept offers exciting possibilities, it’s still in the research phase and faces significant technical and financial challenges before it can become a reality. However, the growing demand for data storage underscores the importance of such advancements, driving continuous research and investment. The creation of 120TB HDDs based on this technology could mark a new era for the storage industry, making it an area to watch as we progress into the data-rich future.
