Seagate plans to dramatically increase the capacity of hard disks. Namely, the plan is to use HAMR technology (using magnetic heat-shrinkable recording), which would increase the density of the input on the hard drive.
This method makes it possible to achieve a dramatically higher typing density in relation to current and dominant PMR (perpendicular magnetic recording) technology. This is achieved thanks to a dramatic increase in heat in certain segments of the disk. The end result should be to increase the capacity of the discs or to increase the input density.
This will increase the overall density and storage capacity of the discs. Heat is used to target specific areas on the disk, which increases the density of enrollment in a particular area. This increases the typing density of the main disk sectors, and the effect is similar to the periphery, although the efficiency is higher when targeting sectors in the center of the hard disk.
The competition is not asleep, so Western Digital plans to do something similar, using the MAMR method (microwave using magnetic recording), which would have a similar effect when increasing the disk density on that disc.
Seagate announced that it expects to deliver the first discs based on HAMR technology in 2020. At the beginning, a capacity of 20 TB was announced, which did not sound so bombastic, as 12 TBs are everyday, and West Digital has recently announced a 15TB hard drive model! But after that, this method should have a hard drive capacity up to 36 TB by 2022, while in 2023 and 48 TB it could become standard.
Finally, if everything goes smoothly, in 2025 we should see the first hard drives of capacity – 100 TB! Ambitious plans, no doubt – we will see if they will be realized. Seagate does not provide disk pricing. Of course, there is always the possibility that hard drives will replace flash memory by then, although it has been written so long to become seriously skeptical …
