They're $7.00 at J&R. For detailed info on capacity at
various record modes check out:

No, you are wrong. There is a linear PCM mode of operation.

A more important one is that for the past five years the only new DAT tapes
that have been of high enough quality to not light up my Sony 7030's error
lights like a Christmas tree have been made by Fuji. Now that DAT is no
longer a major computer backup format while remaining among the most
expensive, there is a serious question of reliable DAT tape stock remaining
available.

Flash memory does have a limit on writes. It's not usually a practical
issue, but it is enough of a consideration to be a certification problem
for flash devices in aviation electronics.

Battery life is about two to three hours of PCM recording on a single NiMH AA
cell. The main advantage of MD is that I can carry a bunch of AA cells in my
pocket and replace the battery each time I change media. This is great for
festivals, etc, where you may record all day.

I'm using electret mics (AT853), with a self-made battery power circuit. I
plug these mics into mic in on the minidisc. I don't think there is enough
gain on the line input of the Jukebox to take these. I'm planning on using an
external preamp and A/D (Edirol UA5) but have not got around to this yet.
Minidisc is just too convenient for now.

High capacity disks are about $7 to $10. But you can record an unlimited
number of times. I've got four discs right now and I just keep cycling
through them. You can also buy lower density media for about $1 each. I use
these for playback of compressed material, pretty similar to MP3 I think. I
happen to like the removeable media more though.

I like a one-box solution. I don't think that a recorder, no matter
how tiny it is, is very convenient when you have to string it together
with an outbouard mic preamp and/or mic power supply.

Is that enough to cover a day's worth of festival recording? Or two,
or three days? These tiny recorders are convenient for short term
projects, but eventually you have to unload them so you can re-use the
media. The nice thing about the Minidisk is that the recording media
is removable and storable. The not-so-nice thing is that its per-hour
cost is fairly high.

Choices and preferences.
