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

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 ...

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 ...

[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 ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

Thus, understanding the magnetic fields ... around a magnet. The team thinks that the measured three-dimensional structure ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

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 ...
