“…Two of them are longitudinal CoCrPt films: one is strongly coupled (labelled CoCrPt-I) and the other is weakly coupled (labelled CoCrPt-II). Lee et al studied their fabrication parameters in [19,20]. The remaining two are perpendicular CoNi/Pt multilayered films: one is strongly coupled (labelled CoNiPt-I) and the other is weakly coupled (labelled CoNiPt-II).…”

We investigated magnetic intergranular coupling in both longitudinal and perpendicular media, suitable for high-density recording. The longitudinal media were two kinds of CoCrPt thin films with one strongly and the other weakly coupled. The perpendicular media were two kinds of CoNi/Pt multilayered thin films with one strongly and the other weakly coupled. The dc saturated and demagnetized magnetic states of thin films were studied by magnetic force microscopy. The demagnetized state of strongly coupled media shows greater contrast than that of granular ones for both CoNi/Pt and CoCrPt. In the dc saturated states, CoNi/Pt shows uniform distribution of the magnetization, while CoCrPt shows distinct remanent magnetization, which is smaller than saturation magnetization. A recording demonstration shows that the perpendicular medium is advantageous over the longitudinal one, and the weakly coupled medium outweighs the strongly coupled one for high-density recording.

“…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.
