HAMR - Computer Definition
(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.
