Toshiba's HDD Tech Roadmap: A Mix of SMR, MAMR, TDMR, and HAMR [anandtech.com]
In an interview published this week with Blocks & Files [blocksandfiles.com], 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.
[...] By adopting MAMR for their 2019 – 2020 nearline HDDs Toshiba and Western Digital can continue using HDD media that is similar to platters used today. By contrast, Seagate is set to skip MAMR and use HAMR along with brand new disks instead.
