The role of stress-induced anisotropy in longitudinal thin film magnetic recording media
Measurements of stress and magnetostriction have been made in longitudinal CoCrTa magnetic recording media. The stress in Cr and CoCrTa/Cr films deposited onto grooved substrates is higher parallel to the grooves compared to perpendicular to the grooves by up to a few hundred MPa. Combined with a ma...

| Zusammenfassung: | Measurements of stress and magnetostriction have been made in longitudinal CoCrTa magnetic recording media. The stress in Cr and CoCrTa/Cr films deposited onto grooved substrates is higher parallel to the grooves compared to perpendicular to the grooves by up to a few hundred MPa. Combined with a magnetostriction coefficient of −3×10−5 in CoCr10Ta6/Cr, magnetostriction makes a contribution to the in-plane anisotropy observed in such media. |
