Blu-ray, also known as Blu-ray Disc (BD) is the name of a new optical disc format that is rapidly replacing DVD. The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc.

You hold two of the "buttons" down at a time and hold for at least 15 seconds (the ones for disc 1 and 2 for example). You may have to play around a bit but you will find the combination for ejecting the disc. It seems to depend on which slot the disc is in, for example in slot 1 or slot 2, etc.

A sata hard drive can vary in home much it holds. For the most part it's in gb. The lowest you will see one hold is about 320 or so, and the highest you can see is about 1 tb or even higher.

I believe disc 2 is the multiplayer disc, so yes.
how much can it hold?
1 gb can hold about 250 or350 songs, pictures and games
Most computers will hold about 1-2GB of RAM but it depends on the computer.
your rectum can hold 1 pound of poo
It depends on what release it is. The date of the picture disc and the condition of the picture disc.
There are 16 layer single sided blu ray discs which have storage capacity of 512gb. That suggests at current abilities a 2 sided disc having capacity of over 1 terabyte. The research and tools for more levels is ongoing. As such it is likely that this will expand a good deal more than that (there is no physical reason why we couldnt double this many more times)
