At the recent Magnetism and Magnetic Materials (MMM) conference Advanced Storage Technology Consortium (ASTC), which unites numerous makers of hard disk drives as well as developers of storage solutions, demonstrated a new HDD roadmap. Apparently, rapid increases in areal density of hard drive media will allow HDD makers to create hard drives with up to 100TB capacity by 2025.
Modern hard drives use perpendicular magnetic recording (PMR) technology which once enabled a rapid HDD capacity boost, but is no longer quickly evolving. It is also believed that shingled magnetic recording technology will also not bring a lot of capacity benefits to hard drives, according to the roadmap. Members of the ASTC believe that the next big thing in hard disk drives is heat assisted magnetic recording (HAMR), which will be massively introduced into HDDs by 2017, increasing the average annual areal density growth rate to 30% (it is currently about 15%), reports Forbes.
