    An accelerated test of the stability of images recorded on still video floppy disks was conducted by incubating disks at elevated temperatures. Small changes in the playback output were detected at 7 MHz, enabling prediction of storage life at ambient temperature by extrapolation. The test method revealed changes equivalent to a few nanometres in film thickness.
