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 ...

Magnetic tape and disks were developed in the ... but they all gave way to USB storage (see USB drive). See optical disc. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires ...

Couplings Types. Couplings can be divided into two categories: flexible and rigid. Both types are used to connect two rotating shafts driven by a motor and transmit ...

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 ...

It turns out that galaxies undergoing a cosmic collision perhaps also need to have a similar “weight” to develop perfunctory ...

The transfer takes place through a non-magnetic containment barrier without any physical connection. The couplings are opposing pairs of discs or rotors embedded with magnets. The use of magnetic ...

For the first time, astronomers have observed evidence of magnetic filaments in the accretion disk surrounding a nearby ...

Researchers have found evidence of magnetic fields associated with a disc of gas and dust a few hundred light-years across deep inside a system of two merging galaxies known as Arp220. They say these ...
