Accelerated Environmental Testing of Magnetic Recording Disks


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.
