  • The CD is a round disc with a hole in the center. CD is used to store a data.
  • The CD holds about 650-700 MB of data.
  • The CD stored the data using the binary digits 0 and 1.
  • The binary digit 0 on the CD is marked as a pit.
  • The binary digit 1 on the CD-ROM disk is smooth and is known as a land.
  • The CD-Audio stores music.
  • The CD-ROM disc stores data for distributing software and large files such as databases and word processors.
  • The CD-R disc enabled the CD-R drive to write  data on the CD-R disc. The data written cannot be erased.

  • The CD-R drive can also write data to the CD-R disc.

  • The optical head of the CD-ROM drive consists of a read laser and an optical sensor.
  • The CD Writer has two lasers, one for reading data from the CD disc and one laser for writing data on the CD disc.
  • The head actuator moves the optical head forwards and backwards from the center of the CD disc to the outer end of the disc.
  • The spindle motor spins the CD in the CD drive.
  • The CD drive loads the Cd in the drive using the tray mechanism or the caddy mechanism.
  • Installing the Cd drive makes it accessible to the system.
  • Aligning the head actuator of the CD drive focuses the laser beam on the CD track.
  • Ahead Nero, Clone CD, and Adensoft Audio//Data Burner enable you to write data to the CD-R and CD-RW.
