I almost bought those some time ago but I have more 720k (double sided low density) disks than I will ever use so I never bought them. Hope it all works out. Those are definitely the right disks. Quite rare these days to find a single sided low density disks.
Most of my storage these days is done with the Android TPDD that I have setup. If you are looking for long term storage solutions you may want to investigate the various TPDD emulators.
