Because the target is
disk, not tape, there is no shoeshine effect.
StorageTek's D-series systems enable customers to flexibly protect and manage their critical data while reducing
disk management resources.
Reference databases are now distributed routinely on optical
disk.
When a
disk is viewed edge-on from Earth, material heading toward the back side of the black hole recedes from our planet, while material spinning toward the front approaches us.
The second approach enables output from backups performed on remote servers to be stored on local
disk. The resulting backup image is transferred to
disk at the central site.
The astronomers also noted a gap separating an inner and outer portion of the
disk. They suspect that a planet carved out this gap as it emerged from the
disk some time in the distant past.
(C[O.sub.2] lasers can be manipulated by robots, but it is a far more complex setup than with the fiber.) What all of this means is that with a
disk laser it is possible to put a scanning head right on the end of a robot arm (e.g., TRUMPF has one that measures 280 x 300 x 174 mm), so the beam manipulation can be a function of both the six axes of the robot and the two of the mirrors.
The new JVC Everio Series camcorders are equipped with an 1.8-inch internal hard
disk drive for extended recording of DVD-quality video.
"Pathlight VX 2.0 really makes
disk backup work for the enterprise," said Bill Britts, executive vice president of sales and marketing, ADIC.
Hard-disk drives provide high-capacity (greater than 100 gigabytes) and moderate access times in an affordable package but, like RAM, are neither removable nor archival, even though in recent years the swap-out capability of drives and media has lead to a change in thinking about the removability of hard
disk systems.
In the experimental part of the study, a one-pass, high-speed impact test instrument and test method to evaluate materials responses on a hard
disk surface have been developed.
The crisis that results from a hard drive failure can be averted by the purchase of a redundant array of inexpensive
disks (RAID) subsystem, which can remove a single failure point by spreading the risk of hard
disk failure over multiple
disks instead of one.
