The bulk of digital content in data centers will remain on magnetic storage media either hard disk drives or magnetic tape.
Data is stored in the magnetic state of the electrodes, similar to the way data is stored in a magnetic hard drive.
The company has controlled its costs by using three tiers of storage with hard disk drives and magnetic tape.
As can be seen, traditional film use is 15% or less with digital technologies such as optical discs, hard disk drives, magnetic tape and flash memory are the bulk of modern recording media.
Hybrid hard drives combine NAND flash and magnetic disks, simplifying storage-element integration for OEM customers and providing a host of end user benefits: superior performance, responsiveness, lower power consumption, greater operating shock tolerance, and data protection.

It is also a vital component of high-voltage wires, magnetic coatings for high-density hard disk drives, fiber optics, fiberglass, catalytic converters and spark plugs.
Of course, they didn't just use any old off the shelf magnet, instead designing custom neodymium iron-boron models that produce just the right magnetic field necessary to make that hard drive completely useless.
In a report last week tech tracker iSuppli found that rising sales of tablet computers are hurting notebook PC sales, resulting in a decline in sales of traditional hard disk drives which rely on spinning magnetic disks.
Spintronic PCs are at least a decade off, but the technology has been in use for several years in the magnetic heads that read and write data to hard drives.
Regarding the longevity of storage media many of the products that we use today, hard disk drives, flash memory, optical discs and magnetic tape will react with the ambient environment and gradually lose the data stored on them or disintegrate over time.
Magnetic tapes can degrade within a decade, while hard disks are expensive and need a constant supply of electricity.

Among today's data-storage devices, magnetic tapes can degrade within a decade, while hard disks are expensive and need a constant supply of electricity to hold their information, creating huge need for power for the "data farms" behind cloud computing.

In addition to a higher storage capacity than past LTO generations, LTO 5 also offers new architecture features such as the LTFS file system that turn magnetic tape into a directly addressable data source, like a hard disk drive.
Like most drive wiping devices, the Guard Dog employs massively powerful magnets that not only render hard drives useless, but VHS tapes, DAT tapes, ZIP drives, and any other magnetic media to boot.
The digital revolution has stirred up quite a bit of controversy in the music world, where you'll still find passionate devotees of old analog gear, who insist that magnetic tape and ribbon microphones do a better job at capturing voices and violins than sound cards and hard disks.
