Each track had its own read/write head. Magnetic drums were used in the 1950s and 1960s. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

Scientists have uncovered a new way to explore the complex transformations of 2D nanomaterials. By using nanoscale vibrating ...

This revealed how the material's vibrations change near its phase transition temperature and, with that, its magnetic properties. "Imagine a drum with a magnetic structure, where the laser light a ...
