Toshiba's HDD Tech Roadmap

@ 2019/03/14
In an interview published this week with Blocks & Files, Toshiba outlined the company will be relying on a mix of hard drive technologies in order to keep increasing hard drive capacities. Along with current-generation two-dimensional magnetic recording (TDMR) and shingled magnetic recording (SMR) technologies, the company will also be tapping both microwave assisted magnetic recording (MAMR) as well as heat-assisted magnetic recording (HAMR) for future drives. Already gearing up to ship its first 16 TB TDMR drives, Toshiba's short-term development plans call for it to adopt SMR as well as MAMR. Meanwhile in the longer-term, HAMR will be introduced for further capacity increases.

Earlier this year Showa Denko, Toshiba’s supplier of HDD media, revealed that the company would be supplying platters for hard drives based on MAMR technology. Toshiba has since confirmed their plans to use MAMR in this week's interview, but in an added twist, the company also noted that some of its high-capacity MAMR hard drives will use shingling as well.
