Today’s Eio post is on Optical Drives.

What is an Optical Drive?

An optical drive uses lasers to read or record information on a disc. Every modern computer comes equipped with an optical drive to read the information on CDs, DVDs, or Blu-ray discs. Outside of computers or laptops, optical drives exist in stand-alone optical drives, such as a DVD or CD player, and many video game systems.

Different Types of Optical Drives

There are three main types of optical drives:

  • DVD drive – DVD drives come with capabilities to read (R), write (W), or read-writable (RW). DVD-R, you can only read the data (ie., watch the video); DVD-W you can write or re-write onto the DVD disc; DVD-RW you can both read and write onto the disc.
  • DVD/CD drive combo – because DVD technology has surpassed that of CD technology, every modern day DVD drive can read both DVDs and CDs.
  • Blu-Ray disc drive – the latest optical disc drive technology is Blu-Ray player. This uses different technology than DVDs, so Blu-ray discs are often unable to be played on DVD players. But DVDs can be played on Blu-ray players.

In the past, optical drives were one of the main sources of saving computer data. CDs surpassed floppy discs, while DVDs surpassed CDs, now Blu-rays are overcoming DVDs. But all of these sources are used to back up small amounts of data. Hard drives, USB flash drives, and SD cards are the main forms of backing up today’s digital information.

Here are the various optical drives and accessories Eio sells:
