Seagate plans to show off its newest storage technology, heat assisted magnetic recording (HAMR), at CEATEC 2013 from tomorrow through Saturday. The company claims that HAMR will enable drives with capacities up to 20TB by 2020. The new technology will achieve this increase by "heating the medium with a laser-generated beam at the precise spot where data bits are being recorded. When heated, the medium becomes easier to write and the rapid subsequent cooling stabilizes the written data. The result of this heat-assisted recording is a dramatic increase in the recorded density." Seagate CTO Mark Re described the motivation behind the new technology saying, "The world is generating an astronomical amount of data annually and that data needs to be stored. We are approaching the limits of today's recording technology and with HAMR technology, Seagate is on track to continue to increase areal density delivering hard drives with the lowest cost per gigabyte and reaching capacities of 20TB by 2020."
