HAMR
From Wikipedia, the free encyclopedia
HAMR is an acronym for Heat-Assisted Magnetic Recording. It describes a technology that magnetically records data on high-stability media such as an iron platinum alloy, using laser thermal assistance to first heat the material. These materials can store single bits in a much smaller area without being limited by the same superparamagnetic effect that limits the current technology used in hard disk storage. The only catch being that they must be heated to apply the changes in magnetic orientaion.

[edit] Outlook
HAMR could increase the limit of magnetic recording by more than a factor of 100. This could result in storage capacities as great as 50 terabits per square inch.
- Seagate believes it can produce 300 terabit (37.5 terabyte) Hard disk drives using HAMR technology.[1] Some news sites reported that Seagate would launch a 300Tb HDD by 2010 but this is wrong. Seagate responded to this news stating that 50 terabit per-square-inch density is well past the 2010 timeframe and that this may also involve a combination of Bit Patterned Media. [2]
