Theoretical question about how CD's work

I love that the OP has orphaned this thread, but people are still arguing about how CD’s work. :D :D :D

Yeah, I’m starting to think it might have been a drive by. 😬

No reason to argue about how CDs work.   It's pretty well documented.  Books are still an inquiring mind's best friend.

P.S. to my previous post:

I recall seeing measured data a few years ago indicating that erroneous reads by the laser mechanism occur vastly more often when ripping at high speeds than when ripping (or playing) at normal (1x) playback speed. Although even when ripping at high speeds the hardware will usually correct at least the vast majority of those errors bit-perfectly (assuming disc and drive are in good condition).

That would suggest, though, that if the particular ripping program being used cannot detect erroneous data and perform multiple re-reads as necessary, and provide an indication to the user if and when uncorrected errors cannot be overcome by re-reading at the particular speed, it would be desirable to rip at low speeds, e.g. 1x or 2x or thereabouts.

>>>>Ah, good one, moopman! The old Skeptics Society chestnut. 🌰 Since everything is known and can be found in Wikipedia or some online textbook we can dismiss any inconvenient arguments as not worthy of examination. Bravo, moopman!

Just for emphasis, anyone who thinks he’s listening to all the information that’s on the disc is badly mistaken. The scattered light problem itself without even going into any of the other problems associated with CD playback accounts for an apparent loss of at least 30% to 50% of performance, in terms of bass articulation and slam, treble performance, air, resolution and size of the soundstage, signal to noise ratio, dynamic range, distortion, compared to the case where scattered light is controlled. It’s not even close, gentle readers. Geez, even a green pen around the outer edge gives a glimpse of what you can get if you control all the scattered light, not just the visible red portion. Hel-loo!
