  6. An optical disc is a storage media consisting of a flat, round, portable disc made of metal, plastic, and lacquer. Optical discs are written and read by a laser. Different formats of optical discs are CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-R, DVD+R, DVD-RW, DVD+RW, and DVD+RAM. Optical drive(s) usually are a standard feature on toady’s personal computers
  7. Users can read but not write or erase a CD-ROM (compact disc read-only memory). Users record their own items such as text, graphics, and audio on a CD-R (compacts disc-recordable). You can write on part f the disc at one time and another part at a later time. Once recorded, a CD-R can be read from as many times as necessary. Each part of a CD-R can be written on only one time. The disc’s contents cannot be erased. You need a CD recorder or a CD-R drive to write on a CD-R. A CD-RW (compact disc-rewriteable) is an erasable disc you can write and rewrite multiple times. Reliability of the disc tends to drop, however, with each successive rewrite. To write on a CD-RW disc, you must have CD-RW software and a CD-RW drive.
  8. A DVD-ROM is an extremely high-capacity optical disc that stores 4.7 GB to 17 GB. DVD-ROM means digital versatile disc-ROM or digital video disc-ROM. The goal of DVD is to meet the needs of home entertainment, computer usage, and business data and information storage with a single medium. DVDs store huge databases, music, complex software, and movies. You must have a DVD-ROM drive or DVD player to read a DVD-ROM. Newer DVD-ROM drives also can read audio CDs, CD-ROMs, CD-Rs, and CD-RWs.
  9. To write on DVD-recordable or DVD-writeable discs, must have proper type o drive. DVD-R and DVD+R are competing DVD-recordable formats. Each has 4.7 GB of storage capacity. Both allow users to write on the disc once and read it many times. DVD-RW, DVD+RW, and DVD+RAM are competing rewritable DVD formats. DVD-RW and DVD+RAM allow users to erase and record more than 1000 times. DVD+RAM allow users to erase and record on a DVD+RAM disc more than 100,000 times.
