I'm disc manufacturer and I'm holding several patent in the disc industry
molding process today is very accurate we talk micron and nanometre,in replication line we have scanners checking every disc,eccentricity is checked on the stamper during the punching and after with very accurate tester.
during the metallization process we spread the aluminum particles to have homogeneous layer in nanometers thickness .
demagnetizing , aluminium impurities, labeling color and blabla is BS!
