Going off on a tangent, the 1970's CD is based on real time output, much like the old vinyl, which at the time was OK.
If low cost memory was available better error correction would have been possible. Transferring data output to storage today makes this possible.
DVD-A was not a hit, but is much better from my experience. Recording quality is a dominant factor in all formats.
Not really wanting to be the pedant here but...commercial CD players not available before 1982 ?
