Even though Heated Assisted Magnetic Recording (HAMR) based drives have yet to reach the market, the future roadmap of hard disk drive technology is predicting the use of the Heated Dot Magnetic Recording (HDMR) recording technique to increase the capacity of hard disk drives significantly. HA
Bit-patterned media (BPM) isolates each bit to improve the stability of each data bit, making it less prone to changes through interference from other data bits or temperature. HDMR will combine this technology to improve the areal density further, which is predicted to enable hard disk drives thought to be able to store data from between 60 to 100TB.
Such advances will be extremely important for the future of traditional spinning hard disk drives. Although Seagate have announced the release of a 60TB SSD this year, it alone will have relatively little effect upon the traditional HDD market.
