Co-γFe_2O_3 longitudinal magnetic recording media obtained by annealing CoO-Fe_3O_4 were prepared on NiO underlayer. The coercivity HC was varied. with the Co content, namely, the atomic ratio of Co/Fe in Co-γFe_2O_3, and the oxygen partial pressure in deposition of Co-O-Fe_3O_4. The H_c of the media with Co/Fe=4 at% was 2000-3500 Oe, 1.3-3.6 times higher than that of Co-γFe_2O_3/NiO media without NiO underlayer. The grain size of Co-γFe_2O_3 became smaller with decreasing the thickness. The read/write characteristics of the media with no overcoat were evaluated in contact recording. Co-γFe_2O_3 media on NiO had higher D_<50> and lower medium noise than those of the media without NiO underlayer. kywe>Co-γFe_2O_3 / NiO underlayer / coercivity / longitudinal magnetic recording medium / R/W characteristic / contact recording</kywe>
