The main difference between DVD and blu-ray is that DVDs use red laser technology whereas blu-ray utilizes blue laser technology.
Before we move to more differences, let’s first understand DVD and Blu-Ray:
- DVD: DVDs, or digital versatile discs, are optical storage mediums that use a laser to read and write data.
- Blu-Ray: Blu-Ray discs are a newer type of optical storage medium that use a blue laser with a shorter wavelength of 405 nanometers to read and write data.
Now, let’s get to DVD vs Blu-Ray:
