Blu-ray discs were introduced to facilitate storing and playing high definition video. They utilize a blue laser, unlike CDs and DVDs that use a red laser.

The shorter wavelength of blue light allows for more data to be packed onto a Blu-ray disc, as it can resolve smaller areas of data on the disc.

Consequently, the physical areas where data is recorded on a Blu-ray disc are smaller, enabling more data to be stored compared to CDs and DVDs. A standard Blu-ray disc can store 25 GB.
