To enjoy your DVD and Blu-ray collections, you typically need a DVD or Blu-ray player. The obvious difference between a DVD player and a Blu-ray player is the laser technology used to record and playback the data. There are also other differences between storage capacity, image resolution and player compatibility.
Storage capacity
A single DVD player can store approximately 4.7 GB of data. The dual DVD player can store twice the amount of data at 8.7 GB.
Single Blu-ray player stores approximately 25 GB of data. The double Blu-ray player holds approximately 50 GB.
Laser technology
DVD players use a red laser with a wavelength of 650 nm to read DVDs.
Blu-ray players use a blue laser to read the stored information. The wavelength is 405nm. This allows for a closer and more accurate reading of the information stored on the disc.
Image resolution
Almost all DVD players have a standard resolution of 480 or an extended resolution of 520.
Blu-ray players are designed for High Definition (HD) viewing and offer the best 1080p picture quality available. Some of them can display Ultra High Definition (4K).
Player compatibility
A basic DVD can be played on both DVD players and Blu-ray players. However, Blu-ray discs can only be played on Blu-ray players because the red laser used in DVD players is too large to read the tiny grooves of a Blu-ray disc.
People's needs are diverse, and we can recognize the benefits of each one. Therefore, it can be difficult to choose one. AutoJoy offers both DVD players and Blu-ray players. You can take a look.
