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 orientation ...

Although the mainstay of the device (storage) to store data is shifting from the magnetic disk type HDD to the SSD using the flash memory, the magnetic disk type storage device has been in storage for ...

Toshiba demonstrated a method for using magnetic fields from microwave radiation to reverse the magnetization direction selectively in a multi-layer magnetic recording media at the International ...

Push two magnets together and you’ll set off an avalanche of activity, forcing atoms on each magnet to align their polarity with the intruding magnetic field. It may sound like a party trick for ...

A new recycling process turns discarded hard disk drive magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste ...

The computer's storage media prior to solid state drives (SSDs). Magnetic tape and disks were developed in the 1950s and commonly used together in companies for decades. Tape was the primary medium ...

An international team of scientists led by astronomers from the University of Wisconsin–Madison has produced the most accurate measurement of the gases swirling around young stars and how their mass ...
