The Playstation 3 games console uses a new kind of laser, it’s called a Blu Ray Laser. The PS3 Blu Ray laser allows for much more data to be stored on a disc the same size as a regular DVD but can the new Blu ray discs hold up to 100 Gb of data compared to the 9Gb of a dual layer DVD disc.
The PS3 Laser contained within the PS3 console supports a range of media including CD, DVD and Blu Ray discs.
Try using a PS3 Laser lens cleaning disc before you
dismantle your console and take your laser out.
