Does a Blu-ray disk hold more than a DVD?

Answer 1

For a few reasons: Blu-Rays hold up to 5 times more data than a standard DVD. Blu-Rays have better sound and picture quality. And Blu-Rays have a special hardcoat layer on the bottom of the disc that makes it more resistable to scratches than a regular DVD.

Answer 2

Normal DVD works on red laser of wavlength 650 nm but blue works on blue laser of wavelenth 450 nm. In small area more data can be stored. so when it is size of normal DVD it can store more data.

Answer 3

As technology improves, so does the storage capacity of storage devices. The capacity of DVD is greater than CD and the capacity of blu-ray exceeds both. The lasers used in blu-ray devices and the material on the disk allow for more densely-packed storage.

Answer 4

Yes, a Blu-ray disc holds more data than a DVD. A single-layer Blu-ray disc can hold up to 25GB of data, while a dual-layer Blu-ray disc can hold up to 50GB. In comparison, a single-layer DVD can hold up to 4.7GB of data, and a dual-layer DVD can hold up to 8.5GB. This increased storage capacity allows for higher quality video and audio on Blu-ray discs compared to DVDs.
