I think comparing the MD format to 2 track analog studio tape machines is the most absurd comparison you could possibly make! Somebody has been monitoring at over 100dB for a few years too many...
MD vs. tape
Realizing that neither of these formats are considered audiophile quality, I'm still interested in a comparison between using a minidisk recorder vs. a cassette tape deck for basic recording purposes. My use would be primarily in the car or for taping FM broadcasts, with an occasional home playback of recorded, borrowed CDs/vinyl. I have no substantial investment in either format, but would be interested in a comparison of buying an MD deck vs. a (probably used) tape deck for these purposes. I assume that both formats will become obsolete within a matter of, say, 5 years. So my expectations are only for a temporary system.
