It means that the disk is damaged and is not repairable. DVD-RWs are notoriously bad. They just don't work nearly as well as -R disks. Unless you can get the disk mounted somehow and copy the library off the disk you're out of luck.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Never having used any -RW media myself, I don't know whether DiskWarrior or other disk utilities are able to make directory repairs on them. If they can do so, fine. But before you buy one, find out for sure from its maker whether it can be used on -RW media.
Failing that, I would use a data recovery utility such as:
Data Rescue II
All three come in demo versions that will show you what the full version could recover before you have to pay for anything. Each will allow you to select and copy recovered files from the damaged DVD-RW to your computer's hard drive.
