What is Blu-ray? How would mini Bluray work?

i never heard of mini Blu-ray but Blu-ray is like a dvd that has the ability to hold high definition video. Hd dvd is a lot like it but Hd dvd can hold a lot less information on it.

There is no such thing as Mini Blu-Ray as far as I know.....you might be refering to Mini Disc which is a format used by Sony long ago. Blu-Ray is essentially the same idea as DVD, but with 1080 horizontal lines of screen resolution on Blu-Ray instead of 480 lines on DVD, which results in sharper picture. Also the sound is better on Blu-Ray providing you have the right equipment.

Blue-Ray is the format for high definition video on DVD. Regular DVDs are not high def. You need a high def TV and blue-ray player to use it.

I would imagine mini Blu-Ray will come about at some point in the next year or two. I assume you're talking about the equivalent to mini-DVDs for camcorders. I see that becoming the ideal media for future HD camcorders, except it will be just like it is now, you're camcorder will always act as the player for these smaller discs. Blu-Ray is just like DVD but burned with smaller lasers allowing 10x as much space or more. This allows for much better resolution and sound and is ideal for the latest tv's available.
