An optical storage medium such as a CD or DVD can store audio and video files, respectively. DVD's are also capable of storing images and other data.
A Bluray disc stores five times more data than a DVD. Therefore, a DVD will not have the capacity to store the contents of a Bluray disc.
BluRay discs carry high definition television and therefore store data in a high density format. A standard definition DVD player will not recognise a BluRay disc and will simply report an error if one is loaded. On the other hand, a BluRay player will not only play BluRay discs but will also handle standard DVDs. Most will also recognise and play CD format discs. Most Bluray players will also down convert the HD signal from a BluRay disc so that it can be viewed on a standard definition television. In this case, of course, the image quality will be the same as any other standard definition signal. To benefit from the high definition signal, an HD television is also required.
It's primary function in consumer electronics is to store and transfer more data than a traditional DVD could.
There are several mass storage mediums that may be described as a disk (or disc), including floppy-disk, hard-disk and optical disc (CD-ROM, DVD, BluRay). Solid-state drives such as flash drives are not disks; there are no moving parts.

CDs, DVDs and BluRay discs all work in similar ways. The primary difference is the data density on each disc. CD is the lowest density. A DVD can store several times the amount of data on the same surface area and BluRay will store several time the amount of a DVD.
