A disk's surface is divided into concentric tracks (circles within circles), and the thinner the tracks, the more storage. The data bits are recorded as magnetic spots on the tracks in one ...

Two researchers who independently developed the neodymium magnet — used in everything from hard disk drives to automobiles — have been awarded the 44th Honda Prize. In 1982, two researchers ...

Use less battery power - devices they are in stay charged for longer. Be more robust - a magnetic disk could be ruined by dropping it, because its moving parts may be damaged.

What we are seeing is that as this black hole forms, the proto-neutron star’s surrounding disk will essentially pin its magnetic lines to the black hole,” says Ore Gottlieb, the study’s ...

[Andrew]’s magnetic pucks are formed from two thick plywood discs with magnets set into the edges. These magnets alternate in polarity around the discs, and they match up with mild steel pole ...
