BluRay is a much larger disc format. Where a DVD can be multiple layers of storage space, it maxes out around 9-9.5 GB of storage space (single layer is about 4.75-5 GB of storage). A BluRay disc can hold about 50 GB on two layers (about 25 GB single layer). This means less (if any) data needs to be compressed resulting in higher quality images, sound, etc. Better gaming, better movies, better data storage, etc. The HD DVD format holds only about 22 GB total.
Blu-Ray and HD-DVD are two new optical storage technologies that fight as the successor of DVD.
With the introduction of high-definition TV (HDTV) DVD storage capacity showed to be insufficient to this application. DVD supports a resolution up to 720x480 pixels, while HDTV works with resolutions as high as 1920x1080 pixels. Just to give you an idea, two hours of high-definition video with data compression requires 22 GB of storage space. Keep in mind that the maximum capacity of a DVD is of 17 GB, if a DVD-18 disc is used (keep in mind that this is a dual-sided dual-layer disc).
So how to allow a higher data storage capacity in order to support high-definition contents? Here is where two DVD successor candidates enter in scene: Blu-Ray and HD-DVD.
In fact a Blu-Ray or a HD-DVD is a DVD disc with a higher storage capacity, allowing you to store high-definition contents. It is important to remark that the main motivation to the creation of a DVD successor was the introduction of HDTV, which requires a higher disc storage capacity, feature a regular DVD cannot provide.

Blu-ray technology uses a blue-violet laser in it, which has a shorter wave-length than the DVD format, which has a red laser in it. The picture is supposed to be clearer with Blu-ray, but I would not run right out and get a Blu-ray DVD yet. It's still not time proven technology. Give it a while. This reminds me of the time that there was a question as to which technology in video-cassette would win out, Beta or VHS. It took a while for the VHS to emerge as the one that would be #1. So, I'd wait.

I think you mean to compare blu-ray and HD-DVD. Both are new optical disc formats that display High definition video content. HD-DVD was the early front-runner, but has been outsold by Blu-ray since the ps3 has come out. PS3 also happens to be the cheapest blu-ray player on the market.
Buy it, you won't be dissappointed.
