Which format is primarily designed for video or larger data storage in optical discs?

The Blu-ray Disc (BD) format is specifically engineered to handle high-definition video and larger data storage compared to other optical disc formats. The key feature of Blu-ray technology is its use of a blue-violet laser, which has a shorter wavelength than the red laser used for CDs and DVDs. This allows for more data to be packed into the same physical space, thus enabling higher storage capacity—typically around 25 GB per single-layer disc and up to 50 GB for dual-layer discs.

Given its capabilities, Blu-ray is the preferred medium for high-definition movies and is increasingly used for other data storage needs that require significant amounts of space, such as video games and large software applications. The enhanced storage of Blu-ray discs is crucial in a world where video content is frequently produced in higher resolutions, making it the optimal choice for larger data storage in optical media.

Other formats, like CDs and DVDs, have more limited storage capacities—up to 700 MB for CDs and 4.7 GB for standard DVDs—which makes them less suited for high-definition content or extensive data storage requirements. DVD-RAM, while designed for rewritable data storage, does not offer the same level of capacity or data quality suited to modern video applications as Blu-ray
