These new type of CD-Rs, as stated earlier are composed of black vinyl (same as the old record LPs).  The standard (CD-Rs, CD-RWs, and commercial audio CD releases) are composed of clear acylic with a very thin aluminum backing (gold has been used for longevity at a considerably higher cost...Pink Floyd--Dark Side of the Moon has been released this way at the cost of > $30US!!!).  
Trouble is...that after about 10 years the aluminum starts to oxidize and flake off causing skipping or interuption of playback (lost data).  It took a while for this to be realized as the CD format did not reach 10 years old until 1994 or so.  Sometimes you can see the "holes" in the aluminum backing.  The flaking can also occur (very badly) by overflexing the disk...which will destroy most of the data on the disk.
However, we all know about the lifetime of black vinyl LP records...unlimited unless, physically damaged...as any rave DJ will tell you (I know a few).  I imagine this will also apply to black vinyl CD-Rs.  There will probably be a changing to this new disk by record companies very soon.
These new disks have been recently started being used by Sony for their Playstation Game disks...
Reburning your collection to these new type of diskS is HIGHLY RECOMMENDED....start with the oldest disks 1st....

So, what longevity problems do old colorless/blue/green/gold cd-r's have? 
Do I have to re-burn all my cd-r's on the new black ones or what? I have 
priceless (to me anyway) rarities by a whole slew of bands, and I don't 
want to worry about the media they're stored on self destructing!
