For an optical disc to be read properly:

  1. Make sure the disc drive is capable of reading the disc type you are inserting (CD, DVD, Blu-ray Disc).
  2. Make sure your device containing the disc drive is placed on a stable flat surface in the position it's intended to be used in.
  3. Make sure you are inserting the disc correctly in the drive. Most optical disc drives can only read discs placed in a horizontal position with the label facing upward, whereas others can read discs in a vertical position as well.

Check your devices documentation if you're unsure what types of discs it can read, how to position your device or how to place the disc into the drive.

  1. Hold the disc by the edges without touching the top or bottom surfaces.
    Proper way to hold a disc being shown.
  2. Inspect the disc for dirt, scratches or visible defects.
  3. If the disc is dirty, use a soft, clean, slightly damp cloth to clean it by lightly wiping from the center of the disc outward.
    Proper way to clean a disc being shown.

    Use water only. Do not use solvents to clean the disc.

  4. If the disc still can't be recognized or played, try it in another unit of the same type or try another disc of the same type in the unit.

Optical discs can store a variety of content types, such as miscellaneous documents, photos, movies, music or software. All this content can either be universally accessed with any type of device or software, or it can be specific to only a device type, such as a computer (PC or Mac), gaming console, disc player, etc. In the case of computers, using the right software is also very important. Certain software can be ran only on specific operating systems, such as Windows or macOS, and certain content can only be read with specific software, such as a document processor, image editor, media player, etc.

The packaging of commercially sold optical discs may provide general usage information and details regarding the requirements needed to access their content.
