- Hi folks,
-
- More than one person have told me that some crooks have been making illegal
- copies of CDs. And one told me that those CDs are worse in fidelity.
-
- I don't know the details of making a CD but as I understood, there are
- micro hills and valleys representing 1's and 0's. Now if the bad guys have
- the technology of manufacturing CD, which part(s) of the process they can't do
- perfectly to cause degradation in fidelity?
-
- Anyone knows if there are REALLY illegal CDs on the market and if so, how do
- they different from the REAL CDs?
-
- Thanks
-
- K.L. Pang
