I have a Sony CDMavica digicam that writes to 80mm CDRs (but not CDRWs).
I’ve been given 4 of them with it, but they aren’t going to last long at the rate I take pictures, so I need more.
The problem is that we have a tax here that makes buying blank media very expensive. A simple 120mm CDR can’t, by law, cost less than â‚¬0.5.
Of course, unusual items like 80mm CDRs are hard to find and even more expensive than 120mm ones. The only shop I’ve found that stocks them wants â‚¬1 for each.
Not wanting to give in to this madness I tried online shops in other countries, but while they have much saner prices they want some â‚¬13 for shipping, even for one tiny 10-cd spindle, so they are out too.
Then I started thinking… I have lots of TDK supercheap standard 120mm CDRs I bought long ago on a trip to Switzerland. I used some, then got a DVD writer and had no more use for them, so I left some 50 of them in a cupboard and pretty much forgot about their existence.
Is there any way to “convert” them?
How would I go to resize them? I know from experience that standard cutting methods (knives, dremel…) create cracks on the delicate reflective layer, pretty much making the whole disc useless. Perhaps with a hot knife? The discs don’t spin very fast at all in the digicam, so it wouldn’t be a problem if they weren’t perfectly balanced and/or round.
Also: once they were cut to size, would I need some sort of hack in order to get the digicam to read them, or would it adapt and just burn them as standard 80mm CDs? I suppose it’s smart enough to know its drive couldn’t possibly read a full 120mm disc…
