To clarify one point - oversampling has *nothing* to do with error
cortrection. Data redundancy and error correction are achieved via the
use of a cross-interleaved Reed_Solomon code (CIRC) data structure
which scatters the data around the disc in such a way that even
drilling quite large holes in the disc will not cause any data loss.


I stand corrected. I must've misinterpreted an article in Mix Magazine 20
years ago.

So what IS the purpose of oversampling???

Keep learning!

Oversampling simplifies the design of the analog portion of the
anti-aliasing and anti-imaging filters, at the expense of more
complicated digital filtering. But digital filtering is "free" because
it is simply encoded into the control firmware of the recording /
playback devices. Also, digital filters produce no noise of their own.
