No, and it never will end. Even if you feel you ever get a pretty good handle on HDDs, you'll find yourself branching into flash, SSDs, etc. and have another mountain of information to attempt to absorb.
There are hundreds, if not thousands of engineers constantly working to design new storage media, then just a handful of us trying to understand how it all works well enough to recover the data. If you were hoping to ever master a field, this isn't going to be it. No one ever fully masters data recovery, no one. We've all got different sets of gaps in our knowledge.
