Laser disc players use lasers to accurately read or write marks on a reflective,coated plastic disc.

It will then self-destruct—not in flames, its inventors hasten to add, but because contact with the air eventually renders its surface opaque, making it impossible for the laser in a disc player to read the data beneath.

The data can then be read simply by scanning the disc with another laser beam.
