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 ...

Half a century later, magnetic tape remains surprisingly well-used in government. NASA uses it to back up vast amounts of ...

Seeking to mimic self-assembly processes that occur naturally, RIKEN researchers have demonstrated that the self-assembly of ...

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 ...

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have developed an innovative method ...

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.

Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.

The pre-fab encoder disks don’t have individual magnets—they’re just a puck of magnetic slurry that gets its polarity on the assembly line. [Erich] reverse-engineered a disk and found the ...

but so far it has not been possible to measure the magnetic fields in a protoplanetary disk. In this research, an ...
