All Optical Disc Formats Explained in Detail for Beginners!

This video explains every major optical disc format from CD-DA to BDXL — what each one stores, how the technology works, and why some formats survived while others disappeared. Covers CD-ROM, CD-R, CD-RW, VCD, SVCD, DVD, DVD-RAM, DVD-DL, Blu-ray, and BDXL in order from oldest to newest.

They all look identical on the outside, but the technology inside each one is completely different. Some can only be burned once. Some can be rewritten a hundred thousand times. And one became the gold standard for long-term archival because unlike hard drives, it doesn't degrade from sitting unused.
