内容記述(抄録等)The pass-wear durability and recording characteristics of Co-γFe_2O_3 perpendicular magnetic recording thin-film disks were measured by using a MIG-type ring head with a gap length of about 0.2μm in contact sliding use. Co-γFe_2O_3 perpendicular magnetic anisotropy films were pre- pared by annealing CoO/Fe_3O_4 multilayers deposited onto an NiO underlayer in air at 280-350℃ The Co-γFe_2O_3 perpendicular hard disk had no protective overcoat layers. The head wear was drastically improved by introducing a liquid lubricant. Reproduction demagnetization did not occur, and no damage or scratches were found after more than eighteen million passes. A D_<50> of 180 kFRPI and a low-density reproduced voltage of 143 nV_<p-p>/{turu-pm- (m/s)) were obtained for a Co-γFe_2O_3 disk with an optimized film thickness and perpendicular coercivity. It is con- eluded that the Co-γFe_2O_3 perpendicular disks are suitable for ultra-high density recording media used in contact re- cording without an overcoat layer.
