Optical Drives

Optical disc drives

Optical disc drive is the size of a small book and has an eject button that opens and closes the drive. CDs and DVDs are the most used discs inserted and removed in the drive. It moves be using a motor and a laser. The motor the disc in the drives super fast and the laser scans and reads the data. The lasers go over the bumps and reads them , optical disc drives are much slower than hard drives. The first Laser disc drive was demonstrated in 1972. The software that you use to burn a disc has its own set of rules about how it interprets and responds to data it receives from the drive about the disc. Based on these rules, the software can tell the drive to burn the disc, burn at a reduced speed, or not allow the burn to occur.

There are a number of other factors that can affect the drive's ability to perform an accurate burn at the fastest possible speed. These include, but are not limited to:

  • Rated burn speed of the disc
  • Requested burn speed from the software
  • Quality and consistency of the disc's dye (even with the same brand of disc, batches may vary in quality from one to the next)
  • Quality and consistency of the disc's coating
  • Width and consistency of the disc's thickness
  • Exact placement of the center hole (the smallest variations from "perfect center," or variation in disc thickness can cause wobble)
  • Vibration
  • Age of the drive
  • Temperature of the disc and temperature of the drive
  • Dust and humidity in the operating environment
