Do you know how a CD is made? Watch this video on the making of CD

Many years ago, people kept their data on floppy disk. That time, there was no CD, not even saying DVD. After many years of technology advance, floppy disk data was then put into CD. Games are no longer stored in small-sized floppy but inside the CD, the far-larger storage. And I remember that time, you can have many data stored in it. But until one day, flash disk appeared, people start to use it to store data which is more convenient in storing data.
