HAMR

(Heat-Assisted Magnetic Recording) A technique from Seagate for increasing the density of bits on magnetic disks by using a more stable recording medium. In order to write the bit into this medium, a laser heats the area momentarily. HAMR density of one trillion bits per square inch is expected to yield drives with 20, 40 and more terabytes of capacity. See superparamagnetic limit and perpendicular recording.

To address these capacity issues, new technology will be required--and that is likely to be heat-assisted magnetic recording (HAMR), which uses electromagnetic energy to locally heat the disk to ease the process of writing data on to it.

Heatassisted magnetic recording (so-called "HAMR"), which is still under development, describes an idea to read/write data on a highly stable media using a laser thermal assistance to possibly achieve the areal density as high as 50 Tbit/[in.sup.2] with patterned bits unless unforeseen conditions intervene; the expansion of HDD industry will continue at a high rate in the future, because of the increasing demand of computers, growth of storage-hungry graphics and multiple application, and conversion of information from paper to the more accessible computer media.
