Heat-assisted magnetic recording

Heat-assisted magnetic recording (HAMR) is a magnetic storage technology for hard drives in which a small laser is used to heat the part of the disk that is being written to. The heat changes the magnetic properties (its "coercivity") of the disk for a short time, reducing or removing the superparamagnetic effect while writing takes place. This magnetic effect sets a limit on the areal density of magnetic recording (how much data can be stored in a given area of a disk). The effect of HAMR is to allow writing on a much smaller scale than before, greatly increasing the amount of data that can be held on a standard disk platter.

The technology was initially seen as extremely difficult to achieve, with doubts expressed about its feasibility. As of 2016, no hard disks using HAMR are currently on the market, but HAMR is in an advanced state of development with demonstration drives produced by companies such as Seagate. While TDK originally predicted that HAMR hard disks could be commercially released in 2015, the current best estimate is that they will arrive in 2018.
