This may be a case where you want to wait a year. The DVD discs are
starting to come out now, with the 2nd generation late this year or next
year. Don't get 1st generation--the standards for F2 is already known and
incompatible with F1. DVD will likely replace CD-ROMs in a few years.

We have a Pinnacle Micro RCD 5040. Works great. Cost was around 1k from
MacWarehouse (800-255-6227). There is a later model, I think. All the
best.

We had the same problem with students and buy a Sony CD-R (2X). The CDs
does not cost so much (About $10). The price of the CD-R was $1000 for
about 1 year ago.

...but will the drives be able to *write* (not just read) the current CD
standard? If you want to distribute info widely (rather than just
archiving), which Judy apparently wants to do, you don't want to do it on
DVD until most people have access to drives that can read them.

The issue of access to read the disks is why we decided to use CD-R's instead of
Zip drives or other storage media. Nearly everyone has a CD player for
retrieving data and the one recorder (Optima 650) can be moved around for
recording. We are fairly happy with this recorder but it seems to me that I get
more recording errors than I would like (2 or 3 image files per 50 need to be
individually recorded or otherwise manipulated, but these are mostly Photoshop
files and these problems may be confined to that type). Not having wider
experience with CD-R's I don't know if it is more or less than typical.
Good Luck,

read-only or if writable, then only to 1st gen DVD. 2nd gen DVD will read &
write only 2nd gen DVD. Current CD-ROM will only read & write to current
CD-ROM. Except probably not to all current CD-ROM; as they go to 12X (maybe
even 8X) they're changing what they hold constant: the angular velocity or
the data density. Currently CD-ROMs change speed as they read from
inside=>out. The "faster" ones hold the rotation speed constant, as I
recall. Anyway there is/will be compatibility problems between <6-8X
CD-ROMs & (8?) 12X and higher ones.

multiple layers of data. The 1st generation is about 4GB, the 2nd about
9GB. I believe they'll be about the same diameter as CDs. Not comparable to
mini-discs.

Judy,
I'd recommend going with a CD-writer too, for the following reasons;
1) Your clients (students, faculty members, etc) are MUCH more likely to have
immediate access to a CD reader than a DVD.
2) CD standard won't dissappear in a hurry because the whole music industry is
locked in on it. It's probable that DVD's will read 'old' CD's too.
3) Assuming a micrograph is around 1MB in size, a CD will hold approx. 600
micrographs - more than enough already. Why would a student, working on your
average sized project, want a DVD that holds 4,000-20,000 micrographs? Of
course it's a different matter for archiving within the EM lab.
4) I don't know the cost of a DVD witer, but I bet it's a LOT more than a CD
writer. You've got the money for a CD writer now. Why wait til you can afford
a DVD?

drives. The introduction of writeable DVD drives is planned only for next year
and of course it will take some time until they become affordable.
