A blue-ray (or blu-ray) DVD player use a blue-violet ray to read the disc. Your current CD/DVD player use a red ray to read the disc. The new blue-ray has a smaller wavelength than the red laser and is therefore able to focus on a much smaller area.
This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold
