Most optical drives today are combo CD/DVD drives that support DVDs and all the CD formats: CD audio, CD-ROM, CD-R and CD-RW. The speeds of the drives are rated by their CD-ROM and DVD transfer rates.

Depending on the specific kind of optical drive - CD, DVD or Blu-ray - the wavelength of the laser will vary, along with the rotational speed of the disc. The CD was the first kind of optical disc ...

The drive also has BDXL support, allowing you to store up to 128GB on a single BDXL disc. Add on 40x CD read and write speeds, and you have one of the best external optical drives on the market.

The ultra-high-density optical memory device would consist of numerous memory cells, each containing rare earth elements embedded within a solid material — in this case, magnesium oxide (MgO ...

A new proposal borrows from the principles of quantum mechanics and a technique called "wavelength multiplexing" to hypothesize an ultra-dense new storage format. When you purchase through links ...
