The history of the hard drive, through pictures. By Lucas Mearian. DEC 31, ... The magnetic disk invented by IBM in the early 1950s contained 100 concentric tracks on each side.

The magnetic hard disk's tenure as a critical part of the storage technology mosaic is entering its sixth decade, and it shows no sign of ending any time soon.

The ultimate speed of magnetic disk drives is at least 1,000 times slower than previously expected.. So claims a team led by physicist Joachim Stohr of Stanford's Linear Accelerator Center that ...

Because the vortices that form on the disks contain two independently controllable and accessible magnetic parameters, they could form the basis for quaternary bits that would contain data written ...

The knowledge may help engineers design more reliable materials for disk drives. Correcting even a single typo in an e-mail means changing dozens of bits of information. For each bit, a magnetic head ...

In conventional hard disk drives, the magnetic disk has to be physically moved to read to and write from the disk. This has the disadvantages of being slow and susceptible to mechanical problems. A ...

Data-storing 'bits' inside hard disk drives have to be turned on and off with magnetic fields. But as bit sizes diminish to improve storage density, the recording heads need stronger and stronger ...

Fujitsu Limited today announced the new MHW2 BH series of hard disk drives for mobile PCs, its first 2.5" HDD offerings to incorporate advanced perpendicular magnetic recording (PMR) technology ...
