“…Along with the advanced metal particle (MP) or advanced metal evaporated (ME) tape media, sputtered media can offer very promising long term solution as the next generation tape media [1][2][3]. Previously, NiAl/CrMn underlayers (ULs) and CoCrTa intermediate layer (IL) were used in order to induce a smaller grain size and better promote epitaxial growth of the hcp structure [4].…”

PACS 75.50. Ss, 75.75.+a, 81.15.Cd Recording characteristics of underlayers (NiAl/CrMn)/intermediate layer (CoCrTa)/CoCrPtBN thin film media sputter-deposited on polymeric substrates were investigated as functions of the magnetic layer and the stack thicknesses. Even a very small thickness of 10 nm of the magnetic layer appeared to be sufficient to preserve the in-plane H c , and gave rise to the improved recording performances due to primarily the sharper effective head field gradient. The thicknees reduction provided benefits in the fabrication side along with presenting a substantial contribution to the overall recording performance. The overall stack thicknees was reduced down to 70 nm.

CoCrPt-SiO 2 films for use as thin film tape media have been investigated. Bias sputtering and high Ar pressure were utilized to achieve desirable media properties ͑good in-plane orientation and enhanced grain decoupling͒ in these media. The in-plane orientation of the bias sputtered CoCrPt-SiO 2 magnetic layer was well maintained even at a high content of SiO 2 as Ru was used as an underlayer and deposited at high Ar pressure. Films of ͑10.0͒ textured CoCrPt-SiO 2 on a Ru underlayer showed a large in-plane coercivity of 4000 Oe and transmission electron microscopy revealed an average grain size of about 10 nm, well decoupled by the oxide. The in-plane coercivity was a strong function of the Ru thickness.
