If hard drive betters optical digital retrieval

Then why doesn't someone develope a cd/dvd player that reads the disk transfers the data to hard drive, and plays it back from the hard drive since it sounds better?
Then when another disk is inserted does it all over again writing over the old data.

MacIntosh made a beast of what you are talking about, it has a 750 GB HD but is like 5K. It may beat a computer but is not worth the sound difference.
