The IBM 350, the world's first hard disk, was released in 1956. As the RAMAC computer's memory, it had space for 3.75 ...

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 ...

[Erich] is the middle of building a new competition sumo bot for 2018. He’s trying to make this one as open and low-cost as humanly possible. So far it’s going pretty well, and the quest to ...

From their models, the researchers found that the strong magnetic fields increased the disk's radiative efficiency, making it brighter.
