When Sony released the PlayStation Portable, they also unleashed a new, proprietary media format called the universal media disc (UMD). Just like anything that's new to the public, skepticism grew concerning this format. Currently, only the Sony PlayStation Portable supports the universal media disc format and only content developers are able to create UMD discs. The disc is only two and a half inches wide and weighs only .35 ounces but it still has plenty of space for material with its 1.8 gigabyte capacity.

The universal media disc works just like a typical DVD disc but unlike a DVD's regional coding or third party encryption technology, Sony developed it's own copy protection. For the UMD, Sony created a protection system that uses a unique ID for each disc (using 128-bit encryption) and the ID of the PSP itself. Now before you get thoughts of making your own UMDs for your PSP, that opportunity hasn't arrived yet.

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 disc’s 128-bit encryption keys works alongside the PSP to create a secure environment for the disc’s content. That will please developers and studios who are desperately trying to protect their work from piracy.

Answer 4

Universial media disc, Mostly used for PSP Games, some dvd's are now being released on UMD

Answer 5

There was once something very similar. A micro blank disc encased in plastic that you could burn to with the right device. The only problem Sony thought of this. They put a flat side on a circle and then came proprietary rights.

Answer 6

No, they are only for PSP's. They are the type of discs on which sony puts movies and games only for the psp. You might be able to find a pc emulator so as to run them on your pc, but they probably don't work all that well yet, the psp hasn't been out long enough for that to happen.

Answer 8

UMD is a data format, not a media format. in other words, it should be readable on a computer, provided you have the necessary software. and a DVD drive, because i believe that is the media format of these discs.

if such software is however available, or even legal, i do not know.
