DVD data disc: burn more than once?

[Christopher11]

I recently burned a project to DVD. It's a data disc, and seems to have worked fine, about 1.2 GB of the four available on the DVD-R I burned with a Superdrive on my G4 desktop.

I told it to write session in Toast 7 Titanium, but when i try to burn something else to the disc, Toast rejects it. With DVD's, can you only burn one data disc? No multiple sessions? It's okay if this is the case, I just want to know. Thanks so much for any replies.

DVD-R means writable only once

DVD-RW means rewritable multiple times

Some applications support multisession DVD-+R, but there is no standard.

More info:

DVD+R is a format for optical data storage. It is similar to, but incompatible with, the earlier DVD-R standard. A DVD+R is a write-once optical disc with 4.7 billion bytes of storage, generally used for nonvolatile data storage or video applications.

Data on a DVD-R cannot be changed, whereas a DVD-RW (DVD-rewritable) can be rewritten multiple (1000+) times. DVD-R(W) is one of three competing industry standard DVD recordable formats; the others are DVD+R(W) and DVD-RAM.

That is not the point. CD-R has a multisession standard. You can add, update, and delete files without recovering the already burned space until the disc is full, in a chain of sessions.

Here's something of interest, the steps linked under the 10.4 section should work for 10.5/10.6 but I haven't tested.

Yeah, exactly. I burn multi sessions CD-R's in Toast until the disc is full, as Cube said. So i was wondering if this is possible with a DVD-R. It's okay though, either way. Thanks so much for all the responses and info.
