Mini Disc repair

["Roy Beckham" royefinch]

I have a mini disc (Hi MD) that was brand new and used to make a single 
recording. Upon returning from my holiday the disc now reads as "No 
Track". I know that it was fine because I even listened to portions of 
it. I had the disc in the lock position so I don't believe that it was 
accidentally erased.

Is there any place that someone knows of that can repair this disc and 
save my recording?

Thanks,

Roy

p.s. A short sample from one of the recordings. Location is Wrotham 
Park, about 300km west of Cairns, Australia. A Pied Butcherbird landed 
on the railing of the verandah. The slight echo is from the corrugated 
tin roof.
