- You are seriously confused.
-
- 1) The laser doesn't "ride" on the surface. The laser shines focused
- light onto the surface where it is either reflected back clearly
- or scattered (to make the 1's and 0's).
- 2) Error correction is just that: correction. If the errors are corrected
- before digital-to-analog conversion then they're not errors any more.
-
- Anyway, no one has offered any reason to believe that gold discs would
- produce fewer raw errors, perhaps leading to fewer uncorrectable errors.
- Since disc players are made with aluminum discs in mind, it seems likely
- that gold discs would be no better, and perhaps worse, than aluminum ones.
- It reminds me of those idiot CD rings that add mass to the discs: they
- only reason they don't break players or make for more errors is that there's
- enough tolerance in the players that they aren't adversely affected.
- I suspect gold discs are the same.
