Digital Video/Versatile Disk Read Only Memory (DVD-ROM)
This optical drive works on a similar principle to the CD-ROM, with a laser being used to read data stored in pits on the surface of a reflective disk. DVDs are read using a shorter wavelength of light (a red laser, rather than an infra-red one). In addition to having a greater data-density, DVDs may be double sided and may be "dual layer".
Really i appreciate the effort you made to share the knowledge.The topic here i found was really effective to the topic which i was researching for a long time.
