Audio Systems: UTOC error of my Sharp MS721 MD player, md player, error message

Question
It can play the MD well. But can't record to the disk. Every time writing to the TOC, the error message will show up.
How can I fix the problem or the only way is replace the recording head. The recording head seem very clean. No dirt on it.
What should i do?

Answer
first try a complete reinitialization, make sure your media is compatable with the recorder, last you might have a bad disc. personally, i'd replace unit with a better one that isn't quite so picky about what brand discs you use........like sony.....g.....
