Optical Minidisc file browser or disk utility?

I know this isn't a programming question, but given the esoteric nature of the question, I figured that the engineering community would be a good place to start. If there's a better category to post this question in, please suggest it.

I have an optical minidisc that contained one track about an hour-plus long - recorded on a Sony MD Walkman. Unfortunately I accidentally recorded about ten minutes onto that disc by accident before I realized that I was overwriting my other track. The new recording created a new TOC that now makes the old material inaccessible. If this were a computer hard disk, I could use something like Disk Warrior to construct a new catalog that would enable me to recover files or portions of them that were not yet overwritten. Is there some similar hardware or software that might allow me to do the same with not-yet-overwritten content on an optical minidisc? A file browser for minidiscs? some sort of way to reconstruct a new catalog that shows everything present on the disc?

Many thanks in advance...

==========
PhotoRec is for browsing computer file systems; it is not suitable for an optical audio disc. What I really need is both hardware and software: hardware other than a consumer minidisc recorder so I can mount the minidisc and then some way to browse the data or reconstruct a new TOC

I've never tried it, but you could see if PhotoRec can find anything on the disk that looks like a file. http://www.cgsecurity.org/wiki/PhotoRec
