Heat-Assisted Magnetic Recording (HAMR) is an advanced technology designed to enhance the data storage capacity of hard disk drives (HDDs). By using a laser to heat a small area of the disk to a ...
The data bits are recorded as magnetic spots on the tracks in one orientation or the other (0 or 1), and the smaller the bit, the greater the storage. See areal density and perpendicular recording.
This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...
