Blu-ray Disc players can play Blu-ray Discs, DVDs, and CDs. Some can also play other types of discs, such as SACDs and DVD-Audio discs.
Can you play Blu-ray on a DVD player?
However, while you can play a DVD in a Blu-ray Disc player, you cannot play a Blu-ray Disc in a DVD player. Anyone who claims otherwise is misleading the consumer.
The reason you can't play a Blu-ray Disc on a DVD player is that the discs contain more video and audio information than a DVD player can read.
The pits used to store information on a Blu-ray disc are much smaller than those on a DVD. Reading the information requires a blue laser, while DVD players use red lasers.
