Abstract

Optical disk memories are assessed in simulated space radiation ionizing environments using cobalt-60 gamma rays and linear accelerator electrons. Total dose and dose rate testing of media including write-once and magneto-optic erasable technologies finds the media to be hard to over 1 Mrad (Si) of total dose over a range of dose rates. Optics, optoelectronics, and other critical technologies are considered, and hardening considerations are presented for total dose, displacement, and heavy particle radiation effects.
