optical disc,optical disk- a disk coated with plastic that can store digital data as tiny pits etched in the surface; is read with a laser that scans the surface Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc. ...
Given the extremely close tolerances of hard disks, this is a good question. We have four active Syquests in our office - two on STs, one on a Mac II, plus one on Doug's ST at home - and freely interchange them. In months of use, we have never had a disk error. This speaks w...
You can also file these “blankets” as strictly for display purposes only, usually on the back of the sofa, givingRoseannevibes. They boasted vibrant ’70s colors (brown, dark brown, brown-ish orange) and even attempting to use them as blankets would result in potential strangulation. They...
While this report was the first to put a name to the concept, others were already discussing the use of redundant disks. IBM's Norman Ken Ouchi filed a patent in 1977 for the technology, which was later named RAID 4. In 1983, Digital Equipment Corp. shipped the drives that would become...
We want to explore the range that gets us up to 5 or 10 atmospheres of helium, pressures that accommodate the use of commercially available diode bars with spectral widths of a few nanometers. We need diode lasers at 780 nm, which today have limited brightness. It’s work intensively in ...
DVDs. Russell used transparent foil as the medium, and then read the data by shining a light through it. Modern optical disks use a laser to read the light reflected back from the recording medium. In addition, Russell's system didn't spin as the data was read, so it could be any ...
Optical laser technology, specifically CD-ROM, and its application to the storage and retrieval of information One of the significant problems of this information age is the production of vast amounts of information in a form that is neither convenient nor cost effe... Lind, D. J - 《M.s...
The direct laser writing of interdigitated microelectrodes is a simple, powerful, low-cost, and high-throughput technique to fabricate MSCs without the use of additional masks or complicated procedures, making it promising for large-scale production of MSCs. However, this technique is currently lim...
