[censored] LF-D111A (Panasonic), and it's a first generation drive.

The second generation drive, at least the Panasonic version of it, has a tray which looks pretty much like a standard CD drive's drawer. IIRC, the model number for that one is LF D-211 or LF D-201. Those drives will read (and write) both size DVD-RAM disks, 2.6 GB/5.2 GB and 4.7 GB/9.4 GB.

The second generatoin drive will only read other DVD media, (like a DVD-R disk someone passes along to you).

There a couple of manufacturers who are currently selling DVD drives which will read and write DVD-RAM discs along with pretty much every other DVD or CD format you can throw at it. Google will give you lists of articles about them.
