Resources for transferring Minidiscs:
The Minidisc transfer and recovery expert is Electronic Design Laboratory in Bristol, England
Caution: After noticing a problem, the less you do to the MD the more likely EDL will be able to recover it.
Berkeley Language Center (510) 642-0767 can also transfer Minidiscs.
Minidisc is an excellent acquisition format for many subjects, but it has never gained the traction of other formats. We would strongly recommend against using Minidisc as an archival format. With proper equipment, Minidiscs can be digitally transferred to gold audio CD-Rs. We generally do it through the computer, but stand-alone transfers can be done as well.
We use two Sony MZ-R37 Minidisc recorders, each with a dedicated Audio Technica AT-822 stereo microphone, for oral history recording.
