* Finding the magnetic disk
drive head in the image and aligning the head with a model previously taught to the system must be done with subpixel accuracy.
MO storage material is a thin magnetic film (similar to magnetic disks
In addition, the system replaces optical storage disks with higher speed magnetic disks
The Storage Machine's main architectural components include a channel network interface, a Storage and Transfer Processor, and a layered storage hierarchy composed of magnetic disk
, multiple terabytes of optical discs mounted in a robotic library, and shelf storage.
Multiple studies have shown that 80% of all data stored on magnetic disk
RAID systems (primary storage) is static data.
The notion that magnetic disk
capacity would outpace tape is also misleading.
A spokesperson for Plasmon said Ultra Density Optical drives and media are less expensive and more reliable than magnetic disk
and DVD library solutions.
reports that companies have spent $40 billion to store 1,400 million terabytes of data on magnetic disk
. Even though storage requirements have now started to increase at more than 100 percent annually, technology is improving in cost/performance at only 35 percent each year.
Currently in the prototype stage, a 1,024-tip device can already write bits in less space--albeit in a spotty manner--than the best laboratory magnetic disk
drives can, the researchers claim.
It also came out with the world's first magnetic disk
drive products to exceed 1 Gb of data in a square inch of space.
When the CacheMaster is used as a RAM disk the reduced disk reads are <.02 ms and it allows for transparent data shadowing of the RAM disk contents to an attached SCSI magnetic disk
