Nope, it applies to pre-recorded MDs as well. An MD still has

Sony ATRAC 4 vs. 4.5. The difference is primarilly in tweaks made to the

No, one is just "better". ATRAC 4 is what is in consumer grade MD
equipment, 4.5 is in Sony's "home studio" grade equipment. What is in pro
studio mastering equipment is quite possibly something
