Discs need to be formatted before they can be recorded to, but other than that, refer to your manual re: DVD Ram use, or ask a Panasonic dealer directly. Mine work perfectly, on two different Panasonic machines, so the issue cannot be insoluble.

They are non-cartridge. The DVD-RAM discs each come in a case similar to what you would get with a music CD or movie DVD. You just unwrap the pack, take one out of its case and put it in your DVD drive.
