The partners intend to create high-density carriers based on a magnetic alloy of iron and platinum (FePt). The current hard drives with HAMR (Hot Spot Recording) technology, which Seagate began shipping to customers earlier this year, are also based on FePt. But Seagate uses glass plates in these models, not aluminum – that’s where Showa Denko has specialized in recent years. At the same time, the Japanese company Hoya, a manufacturer of glass plates for hard drives, claims that the recording density of HDD can be increased only on glass plates, while aluminum is not suitable for this purpose.
A new hard drive capacity break is set. Cooperation between Seagate and Japanese experts promise the emergence of the next generation HDD with a record high volume of 80 terabytes. The Japanese company Showa Denko, the largest independent manufacturer of aluminum magnetic hard disk plates, has announced a partnership with Seagate to develop next-generation media. 3.5-inch devices with a capacity of up to 80 terabytes (TB) are expected, though not soon. It will be interesting for the industry if Showa Denko adapts HAMR technology to its aluminum plates, refuting the claims of competitor Hoya.
