magnetic disk Scientific  

1. A memory device, such as a floppy disk or a hard disk, that is covered with a magnetic coating. Digital information is stored on magnetic disks in the form of microscopically small, magnetized needles, each of which encodes a single bit of information by being polarized in one direction (representing 1) or the other (representing 0).

Example Sentences

The goal is to exploit spintronics to create a new type of storage that would consume less energy than magnetic disk drives but be as high-performing as solid-state flash memory - a more expensive alternative.

"The spin valve sensing device allowed one to detect much tinier magnetic fields and therefore smaller magnetic regions in a magnetic disk drive," he explained to the BBC.

From BBC • Apr. 9, 2014

"It would be as fast and reliable as conventional solid state memories but would be as cheap and capacious as a magnetic disk drive - basically containing the best of both worlds."

From BBC • Apr. 9, 2014

"None of those things would be possible without the immense capacities of magnetic disk drives at the very low cost that is possible today... thanks to this spintronic sensing device."

From BBC • Apr. 9, 2014

They generally store that information separately in what is known, colloquially, as memory, either in the processor itself, in adjacent storage chips or in higher capacity magnetic disk drives.
