CCCD means Copy Control CD. You can take a look on this article directly to Avex site :

It doesn't allow ripping but allows some copy ( like on a minidisc for example )
It prevents u to see the tracks in explorer but in Open MG for Sony Net MD you can see it.
Normally an autorun player start on a PC ...but if you use Media Player or Real one and select ' Play Audio CD ... it works well ...so what's the advantage..
And now I 'm sure that some programs can rip them ...(I know some ppl who have tried ).
For the moment I encoded my CCCD legit album to Open MG only and played them with the Sony player.
