Two-track portable
The most obvious choices:
- DAT (
e.g. Tascam DA-P1).
- Minidisk. People are selling these dirt cheap on eBay.
The Minidisk uses lossy data compression, the DAT doesn't. On the other hand, the price is
way different. Both of them are dead or dying formats.
Other choices that might be worth considering, depending:
- Laptop computer.
- Cassette deck. I'm guessing that to get a recorder that's good enough to compete with a minidisk, you'd spend more than the minidisk unit costs, so I'm not sure I'd bother, unless a more generally compatible format is important to you.
- Portable CDR recorder. While there are tons and tons of portable CD
players, portable CDRs seem pretty rare. I think I say a Marantz one in a catalog or something, though.
- Handheld dictation unit.
- Nagra.
