UNDERSTANDING DIFFERENCE BETWEEN CD DVD & BLU RAY

May 12, 2016  •  1 Comment

As of today, there are 3  different types of optical disc used  to store music and movies, commonly known as  CD, DVD and Blu-ray. All these Disc store media in a digital format, commonly known as Standard Definition, High definition and Ultra High definition (4K). In short SD is 480 Pixels, while HD is 2,073,600 or 2 Million Pixels and UHD or 4K has 8.2 Million Pixels.

CD is the oldest of these format , it can store 700 mega bytes of data and are usually used for storing music. The  CD can be played on a CD player, DVD player and the latest Blu-ray players.

DVDS  on the other hand were developed to replace old VHS cassettes, a DVD can store  up to 4.7 Giga bytes of data and are normally used for standard definition movies. these discs can be played on both DVD and Blu-ray player, while many computers also offer DVD writers and players.

BLU RAY is the newest and the best format which can store a massive date of 50 Giga bytes which is equivalent to 70 CDs or  over 10 DVDs.  So we can say, Blu-ray allows us full HD video which is 1980 X 1080 = 2,073,600 or approx 2 Million Pixels. Since, Blu-ray has large amount of storage available allows much sharper and more life like images as well as stunning digital surround sound that really provides movie theater experience. So Blu-ray is not only picture sharpness, richness in color and the wide screen but also about quality of sound.

We offer Full HD {Blu-ray Disc) video to our clients and in near future will be offering 4K videos. Hope this was helpful. if you want more detailed information send us an e-mail and we will be happy to answer all your questions.

I have been looking into disc duplication and need to decide in between cd and dvd duplication. I knew that cds were usually used for music and dvds for movies, but that's pretty much it. Thanks for explaining how much the size differs in the two types of discs.
