This is kinda cool flashing back to different audio formats, maybe someone can find the components to match this...

And here is some fine print I pulled off the inside cover of a CD:

The Compact Disc Digital Audio System offers the best possible sound reproduction - on a small convenient disc. Its remarkable performance is the result of a unique combination of digital storage and laser optics.

For best results, you should apply the same care in storing and handling the Compact Disc as you would with conventional records. No cleaning is necessary if the Compact Disc is always held by its edges and is replaced in its case directly after playing. If the Compact Disc becomes soiled by fingerprints, dust or dirt it can be wiped (always in a straight line, from center to edge) with a clean and lint free, soft dry cloth. Never use a solvent or abrasive cleaner to clean the dsc. If you follow these suggestions, the Compact Disc will provide a lifetime of listening enjoyment.
