What is UMD?

The Universal Media Disc is Sony’s proprietary technology that works exclusively on their PSP handheld gaming console. With 1.8 gigabytes of storage capability, a universal media disc would be a great medium for consumers to store large amounts of their personal data to use on the PSP. Although Sony hasn’t announced any plans for recordable universal media discs, this would be a great opportunity for PSP users.

The outside of the universal media disc is protected by a hard shell with a small portion of the shell cutout to allow for playback. The disc is approximately half the size of an actual CD. The universal media discs 128-bit encryption keys work alongside the PSP to create a secure environment for the discs content. That will please developers and studios who are desperately trying to protect their work from piracy.
