My apologies. And thank you, Jim, for finding a way to stop my posting.
You're a kind and patient crowd--Gordon.

Now I understand, thanks.

Whoa! One of the neat things about minidisc is that it's hard to
overwrite! Apparently you've been using the -one- sequence of
operations that -will- overwrite!
On my Sharp you have to:
play
pause
record (message: erase?)
enter
But if you are in stop, and just hit record, you get a new track and
it doesn't touch any of the previously recorded tracks.
What model recorder are you using?

Subject: Re: Minidisc Mic Input
I finally got the basic mic wired up and I'm now
experimenting with it. The AKG C410 is described
as a prepolarized mini-condenser and is intended
as a headset vocals mic. It can run on 9-52VDC of
phantom power so I have two 9V batteries on it
for 18V. For a load it is spec'd for 1000 ohms
or greater so I ran it directly into the minidisc
through two big electrolytic coupling caps. I have
both channels equal for now (shorted together at
the minidisc plug).
I have the mic mounted on the 24" Edmund's dish,
which ends up being pretty heavy to hold for any
length of time so I added a neck strap, which also
seems to help reduce handling noise. For headphones
I'm just using the cheap walkman MDR-027's. I tried
my AKG240's but the volume was lower. I am working
with a lot of unknowns here since I don't even
know if this minidisc unit is working right. How
loud should an MZ-R50 headphone output be? I have
the volume at max and the ALVS set to "norm" and
the mic sensitivity set to "high." I see the meter
hit max if I speak directly into the mic. The meter
seems to indicate the same reading on playback as
during recording. It that true? A cardinal chirping
thirty feet away only got the meter up to the
midpoint of the scale as did a bluejay at 75 feet.
My inclination is to buy a low noise op-amp and build
a preamp with a volume knob I can tweek. Also I want
to mount the minidisc on the top of the dish handle
so I can watch the meter. I also need to pick a color
and paint the dish. I haven't set the microphone on
fire yet and I don't want to.
