Although magnetic storage
promises 25 years, the reality is that the magnetic tapes need to be backed-up or re-recorded every two to five years and the hardware needs to be replaced every five years.
Key words: beta-decay; magnetic storage
; Monte Carlo simulation; neutron lifetime; superconductivity; UCN.
The conventional data storage industry should be financially healthy over the next few years, as more hard copy data is transferred to magnetic storage
and as stabilizing drive prices, slowing technology development and increasing volumes lead to large revenues and decent margins.
Indeck found that instead of translating a magnetic signal into bits that are then indexed by a computer processor, he can use high-speed parallel magnetic sensing systems already present in modern magnetic storage
devices to help searches.
Combining optical techniques and magnetic storage
media, HO technology will likely be used in magnetic drives to improve data density.
"Traditional magnetic storage
is advancing so fast that the window for holography is shrinking," says Kippelen.
By far, the most mature media is magnetic storage
, and this is reflected in the data returned by manufacturers for this month's JED sampling.
Laser Magnetic Storage
International Company (LMS) has introduced the CM206 CD-ROM drive.
Both she and Mueller include comparisons of rewritable optical disk technology with CD-ROM, WORM, and magnetic storage
Some view this relative newcomer in optical storage as the ultimate in mass storage technology since erasable optical disks combine the storage capacities of optical technology with the reusability of magnetic storage
. High-volume data users increasingly will find erasable optical disks an acceptable alternative to large magnetic storage
Current magnetic storage
and recording devices, such as computer hard disks, contain nanomagnets with two polarities, each of which is used to represent either 0 or 1 -- the binary digits, or bits, used in computers.
