LR Off-line DVD Storage - Any Thoughts on How to do

Question

After time passes, I like to move raw files from my hard drive to a DVD. I want to continue to keep these raw files that have been moved to the DVD as part of my LR catalog, including their thumbnail image. This way I can easily locate raw files stored off-line on a DVD. So far my solution is to take all of the files that I will be moving to a DVD, add them to a child-collection called for example DVD-32 (parent collection is called DVDs-RAW Files). I also, select all of the files and add the keyword, in this example 32. Then I copy these files to the DVD-32, delete them from the hard drive. The folder(s) shows as red in the LR library folders. Each files thumbnail is still retained. When I select a file, I know what DVD it is stored on by looking at the keyword. The reason I created the collection of files on a DVD is to provide an easy way to know what files are on a particular DVD. This is a more cumbersome process than what I did using IMatch, which was designed to catalog off-line files. I wonder if there is a simpler way to do this in LR.
Thanks for any thoughts on this.

Also there are some pretty worrying reports about DVD and CD reliability unless you use the Gold Archive disks [that I use, but I no longer archive to DVD or CD].
I now use a grandfather, father, son backup/archive method with grandfather,father in my safe deposit box. When I feel enough changes have been made, I put son in SD box and bring out GF, reformat, check for errors, and do a backup to set the new baseline.
I check my HDs for errors frequently.
I only lost data once, that was when I was replicating deletes and my main HD got corrupted and I transferred those deletes to my backup. I like being able to "look" at my backup/archive files.
People may say that I should still archive to optical media, but to me it is no more safe than my method. I would have to constantly re-read my optical disks to make sure they were not failing.
Also, I expect to pass the 20,000 file mark this year and that is about 25 DVDs [expect 95 GB or so] and making sure they are good looks daunting. Maybe when/if the blue ray technology arrives with appropriate archive/validation s/w I will change my mind.
Meanwhile, I am looking at ads for 500 GB HDs :-)
