Depending on the type of optical drive and software installed in your computer, the optical drive plays,
copies, and creates CDs, DVDs, or BDs.
Using optical discs (CDs, DVDs, and BDs)
An optical drive, such as a DVD-ROM drive, supports optical discs (CDs and DVDs). These discs store
information, such as music, photos, and movies. DVDs have a higher storage capacity than CDs.
Your optical drive can read standard CD and DVD discs. If your optical drive is a Blu-ray Disc (BD) drive,
it can also read BDs.
