Retrieving Lost Songs On Minidisc?

md freak asks: "I have a Sony MD deck and one of my MD just went 'blank' due to...I don't know what, but I have heard that certain procedures could be performed to retrieve the songs. Does anyone know what these procedures might be?" If anyone has experience with minidiscs who can tell this fellow whether or not there is a chance of recovering the lost data, please spare us some knowledgeable words on the subject.
