Blu-ray
/ˈbluːˌreɪ
/noun [mass noun]
A format of DVD designed for the storage of high-definition video and data.Despite its flawed story structure, The Tale of Despereaux looks flawless on Blu-ray....
- To me, some DVDs look more like 35 mm than Blu-ray does.
- Presented in 1.85:1 1080 p widescreen, High School Musical 3 is far from the most impressive Blu-ray on the Disney slate.
Origin
Early 21st century: from blu, a respelling of blue1 (from the colour of the laser used to read and write this type of DVD), + ray1.
