Toshiba Demos Tech That Will Deliver Huge Capacity HDDs Topping 30TB In The Near Future
The specific technology that Toshiba has pioneered is called "Microwave Assisted Switching-Microwave Assisted Magnetic Recording", or "MAS-MAMR". The Japanese company explains that increasing HDD data density requires overcoming a "trilemma" of issues: reducing physical size of magnetic grains on the disc, improving thermal stability of the grains, and maintaining recording performance at a given density.
Toshiba already ships drives based on MAMR technology, but that form is known as "Flux Control MAMR," and obviously not as advanced as the new tech. Toshiba's current FC-MAMR drives can store up to 18TB per drive. The new MAS-MAMR technology could allow Toshiba to begin shipping drives "with large capacity of over 30TB".
However, despite Toshiba repeatedly indicating that it plans for "early commercialization" of MAS-MAMR technology, the company gave no actual timeline for when drives bearing the technology would find their way to market.
