Sue, Fantastic. I would suggest once you get the +RW full and set up the way you want it, you copy it over to straight +R as time allows though. More stable material primarily. My prior job at the University was mostly computer repair and assistance tech and 'general nerd'; had a lot of staff come in asking about why they couldn't play or view cd's they had created. In the case of audio CDs they had left them in their cars during the summer heat and the media just literally died. One other had stored her photos and photo CDs out in a storage unit; as best we could determine, heat got them as well. Having done a lot of reading on the subject; it appears the dyes in the +R (both CD and DVD) is much more stable in the long run than the dye used in the -R discs; neither is all that tolerant of heat however.
By the way, the thing that makes a disk rewritable is a dye contained within the media that melts at a high enough temperature -- so when you rewrite on an RW disc, a high powered laser melts this dye which fills in the earlier pits and valleys; then the writing laser repits them again. So, enough heat held long enough can cause this to occur even when in the disc storage container.
However, if your treat them well, they will last a very long time and you as well as the kids and grandkids will be able to enjoy them for years to come.
Sorry, here I am on platform again; I've gotta learn to stop doing that!!!!
Best wishes on your future plans - sounds like you are going to have a blast!!!
