Hacking a Sony MDH-10 Drive to Read Audio Tracks?

Help Needed asks: "I recently purchased a Sony MDH-10 Data Drive, and am intrested in getting this drive to read the Audio Tracks as raw data, but all it shows is Okb for each track (similar to looking at a CD). Now, I understand the basic structure of the Disc, the TOC, the music format (ATRAC1, MDLP is ATRAC3), and the way the MO reads. What I am interested in is hacking the MD Data Drive to allow it to read from an Audio Disc. I know it can be done, but am unsure of how to access the firmware of the drive (currently prevents access to write to the tracks). You can go to my webpage to read a short explanation of my idea."
