Hi,
I have just received a brazilian magazine concerning what they claim to be a solver to the problem of CD piracy. It is called SMD: Semi Metalic Disc.
Although they do not describe exactly what it is, to me it looks like a variation of a CD single or similar to those old compact vinyl records with 4/7 songs.
It says that it can reduce up to 80% the final cost of a CD to the end consumer.
I promise to publish more info as I get it.
