Its limitations became noticeable asHDTVemerged, TV screen sizes increased, and video projectors became more common.
Blu-ray aimed to answer DVD’s shortcomings.
It allows you to see more depth, a wider range of color shades, and more image detail.
DVD uses red laser technology.
A blue laser light beam is narrower than a red laser.
The blue laser focuses more precisely on a disc surface.
Taking advantage of this, the pits on the disc where information is stored can be made smaller.
This means more pits can be placed onto a Blu-ray disc than a DVD.
Increasing the number of pits gives the disc more capacity, allowing for the storage of high-definition video.
Blu-ray also provides more audio capacity than the DVD format.
DVD supports Standard Dolby Digital and DTS audio.
