You can save and load tapes in 2mhz mode if the device would allow
for it. I used to use a Sony MD Walkman (minidisc recorder) and it
worked fine. I've never seen a tape deck able to do this. Maybe
it's the audio tapes themselves, but I remember using a VCR in SP
mode a Long time ago and it worked.
