摘要： The present invention provides a perpendicular magnetic recording medium that reduces medium noise and achieves thermal stability of recording magnetization. This perpendicular magnetic recording medium has a substrate and a recording layer formed by single-layered magnetic nanoparticles that are aligned at uniform intervals. An auxiliary magnetic film that is thinner than the recording layer is interposed between the substrate and the recording layer. The magnetization of the magnetic nanoparticles is secured by the exchange interaction effect of the auxiliary magnetic film.

摘要： A magnetic recording medium is provided. The magnetic recording medium comprises an in-plane magnetic film used for recording, and a perpendicular magnetic film formed on the in-plane magnetic film. The in-plane magnetic film has a magnetization easy axis in an in-plane direction. The perpendicular magnetic film has a magnetization easy axis oriented in a direction perpendicular to the magnetization easy axis of the in-plane magnetic film. A tBr (a product of a thickness and a residual magnetization) of the perpendicular magnetic film is set so as not to exceed one-fifth of a tBr of the in-plane magnetic film at the maximum.

摘要： A storage system has a storage medium, a head, and a control unit for carrying out refresh processing. A refresh operation extracts data that needs to be refreshed by measuring the read-out output level of target data. Then, data requiring refresh is re-recorded to the storage medium by the head. Because an actual data level is observed, it is possible to accurately detect refresh target data, and because there is no need for a reference area, it is possible to prevent a reduction in storage capacity.

摘要： A magnetic recording layer is formed on an auxiliary magnetic layer in a perpendicular magnetic recording medium. The auxiliary magnetic layer has the axis of easy magnetization in the vertical direction perpendicular to the surface of a substrate. The perpendicular magnetic recording medium reliably allows establishment of the magnetization in the auxiliary magnetic layer in the vertical direction. When a magnetic flux flows along the vertical direction perpendicular to the surface of the magnetic recording layer, the magnetic flux flows across the magnetic recording layer in the vertical direction. The magnetization is thus reliably established in the magnetic recording layer in the vertical direction. The magnetic field of a stronger intensity is thus leaked out of the magnetic recording layer in the vertical direction.

摘要： A perpendicular magnetic recording medium includes a magnetic orientation controller layer serving as a layer for controlling crystalline orientation in an upper layer. A non-magnetic orientation controller layer extends on the surface of the magnetic orientation controller layer The non-magnetic orientation controller layer serves as a layer for controlling crystalline orientation in an upper layer. A magnetic recording layer extends on the surface of the non-magnetic orientation controller layer. The perpendicular magnetic recording medium allows a reliable establishment of a uniform crystalline orientation in the magnetic recording layer based on the influences from the magnetic and non-magnetic orientation controller layers. A reliable establishment of a uniform crystalline orientation can be achieved without an increase in the thickness of the non-magnetic orientation controller layer.

摘要： An ion implanting apparatus is provided, which can accurately measure a quantity of atoms that are implanted. The ion implanting apparatus according to the present invention has an object to be measured, and the object to be measured is arranged in an irradiating range in which ions are irradiated. When atoms are implanted into an object to be processed by irradiating ions of a processing gas and neutralized particles thereof, the object to be measured is heated through the irradiation with the processing gas ions and the neutralized particles. A control unit determines a quantity of the atoms that are implanted into the object to be processed from the temperature of the object to be measured.

摘要： A magnetic recording medium suppresses effectively side erasure even when recording dot intervals are reduced. Magnetic dots and a soft magnetic layer are provided on a soft magnetic underlayer with a nonmagnetic layer intervening, so that magnetic dots are separated by the soft magnetic layer, and consequently leakage flux during recording to magnetic dots is absorbed by the soft magnetic layer, side erasure can be suppressed, and moreover the soft magnetic underlayer and soft magnetic layer are separated, so that an influence on recording/reproduction characteristics can be prevented.
