Verbatim BD-R SL, 25GB, 10 spindle

The Blu-ray technology has led to the introduction of disks with high storage capacity to meet the increasing demand driven by the rapid growth of high-definition television (HDTV). The name Blu-ray disks is derived from the blue laser technology. The shorter laser wavelength results in a blue light beam. While DVD media are read using red laser technology at a wavelength of 650 nm, the blue laser operates at a wavelength of 405 nm. The advantage of a blue laser with a shorter wavelength is that smaller data pits can be written, thereby increasing the amount of data on the disk. Blu-ray disks offer three to five times the storage space of conventional writable DVDs, allowing for the recording, playback, and rewriting of high-definition (HD) videos.
