Look at DDR SuperNOVA 2. It has about 350 songs, not counting the actual video game on the screen. I'm surprised a PS2 (which is what the arcade game is running off of) can hold that amount of information. How much information can be stored into a disc, and how much information can video game systems read from it?|||How much info it can hold depends on the disk drive in the system. For PS2, as you are talking about (as well as Xbox, 360, and Wii), it can use dual-layer DVD9s, meaning 8.5 GB of space for a single disk. Considering I convered my entire 100+ CD collection to MP3s on the PC and it only took up 3GB (about 1 MB per minute overall at default compression settings), music, when properly compressed, does not take up much room. Most games use up the vast majority of disk space on graphics and FMVs. Both of these in DDR are low quality, so they don't take up all that much space anyway. PS3 uses Blu-Ray, which is 25GB single-layer. They are still working on getting dual-layer Blu-Rays to be reliable enough for mass production
