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 ...

[AnotherMaker] discovered something that might breathe a little more life into those dead disks — magnets ... a spot in the disk that is going bad, and the stronger magnetic field is required ...

Thus, understanding the magnetic fields ... around a magnet. The team thinks that the measured three-dimensional structure might create strong turbulence within the protoplanetary disk.

One thing we’d suggest is switching from a disc to a cylinder with magnets placed in a Halbach array to direct as much of the magnetic field into the interior as possible, with coils of copper ...

ALMA was able to measure the polarization of dust grains in the protoplanetary disk ... to a magnet, the dust grains in this planet-forming cloud are aligned with magnetic field lines running ...

Magnetic devices are components for creating, manipulating or detecting magnetic fields. This can include magnetic memories, magnetometers and devices for magneto-optics. Magnetism can also play a ...

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 ...
