Blu-ray disc players can play Blu-ray discs, DVDs, CDs, and some can also play other types of discs, such as SACDs and DVD-Audio discs.
However, although you can play a DVD in a Blu-ray Disc player, you cannot play Blu-ray disc in DVD player. Anyone who claims otherwise is misleading the consumer.
Why DVD Players Can’t Play Blu-ray Discs
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 is designed to read.
The “pits” used to store information on a Blu-ray disc are much smaller than a DVD, which requires a blue laser to read the information, whereas DVD players use red lasers.
Blue lasers produce a shorter wavelength light beam, which is needed to focus on the smallest pits in a Blu-ray disc. Disc pits are where video and audio information from Blu-ray discs (as well as DVDs and CDs) is stored.
Why Blu-ray Disc Players Can Play DVDs
The reason a Blu-ray disc player can play DVDs is because the manufacturers decided that all Blu-ray disc players include blue and red lasers so they can play both Blu-ray discs and DVDs.
A red laser produces a beam of light with a longer wavelength than a blue laser, allowing it to read the larger pits printed on DVDs and CDs.
When you put a DVD into a Blu-ray disc player, it activates the red laser assembly so the DVD can be played.
When you place a CD in a Blu-ray disc player, the same red laser assembly used for DVDs is refocused to read the CD.
You don’t need to buy Blu-ray discs if you don’t have a Blu-ray player
If you don’t have a Blu-ray Disc player, you don’t need to buy a Blu-ray Disc version of a movie. However, if you have a Blu-ray disc player in your main room and a DVD player or two in other parts of the house, you will need to purchase both the Blu-ray and DVD versions of the film if you want to take full advantage of the advantages. of both formats.
To help solve this problem, and as a way to make purchasing Blu-ray discs more acceptable to consumers who have both a Blu-ray disc player and a DVD player in the house, studios often include both a Blu-ray disc version and a DVD version of a movie in the same package.
The Blu-ray Disc/DVD Flipper
In 2009/2010, Universal Studios experimented with a test of so-called “pinball discs” (Blu-ray on one side and DVD on the other). The titles included three entries in the Bourne series: Bourne Identity, Bourne Supremacyand The Bourne Ultimatum – they were only offered individually – not in a box. Other “Flipper Disc” titles included Traffic, Letters for Julietand maybe a few others. For more details, read the article from Blu-ray.com
Ultra HD and Blu-ray Disc Players
Another disc format is also available: Ultra HD Blu-ray.
The Ultra HD Blu-ray format is actually different from Blu-ray and DVD. You cannot play Ultra HD Blu-ray discs on standard Blu-ray or DVD players. However, Ultra HD Blu-ray disc players can play Blu-ray discs, DVDs and music CDs.
Not all Ultra HD Blu-ray players are compatible with 3D Blu-ray discs.
If you still buy and collect DVDs, a DVD player is fine, and if you also have a Blu-ray disc player, you can still play those DVDs. Since most Blu-ray Disc movies come with a DVD copy, you have both options to play the same movie on Blu-ray Disc and DVD players.
However, Blu-ray disc players are very cheap these days, so if you want to play Blu-ray discs in other rooms of the house, getting another Blu-ray player is an affordable option, when you factor in the added convenience. .
If you have a 4K Ultra HD Blu-ray disc player, although you cannot play a 4K Ultra HD disc on a Blu-ray or DVD player, most Ultra HD disc movies also come with a copy of Blu-ray disc, which softens the blow of jumping to another format.
