That's not correct - Audio CDs have extremely good error correction.  You
can completely remove all data in a slice a couple of mm wide with no
effect on the output at all.

Part of the design spec for CDs was that they had to be very cheap to make.
That means the information on them has to be very tolerant of manufacturing
faults.  That means very good error correction.
