Influence of seedlayer on film microstructure of Co-Cr-Pt longitudinal recording media fabricated on plastic substrates

摘要

Magnetic recording media fabricated on plastic substrate are attractive economical media for multipurpose data storage applications. The substrate temperature can not be increased over 150°Cduring film deposition because the substrates become soft. Therefore, growth mechanism of magnetic thin films deposited on plastic substrates is different from that on conventional glass and NiP-plated Al-alloy substrates. In the present study we investigated the influence of seedlayer on the surface morphology and the growth orientation of Co-Cr-Pt longitudinal thin films fabricated on amorphous polyolephin (APO) substrates.
