Abstract :
Metal particulate tape was prepared using stabilized metal particles, and the corrosion stability of the tape was examined under various environmental atmospheres. The decrease of magnetization after exposure to 60°C/90% RH (relative humidity) for four weeks was bout 7%. When the tape was stored in a low concentration of pollutants of Cl 2, H2S, and NO2 gases, the change of magnetic properties was within about 0.6%. These stable characteristics show that the stabilized metal particulate tape is suitable for data-storage media
