20100003422 | DEPOSITION APPARATUS, FILM MANUFACTURING METHOD, AND MAGNETIC RECORDING MEDIUM MANUFACTURING METHOD - A deposition apparatus includes a plasma generating unit that generates an arc discharge between a target and an anode to generate plasma; a deposition chamber in which a base is disposed; and a plasma transfer unit that transfers the plasma to the deposition chamber, wherein at least part of the plasma transfer unit is electrically separated from the plasma generating unit and the deposition chamber, and a negative voltage is applied to at least part of the plasma transfer unit. | 01-07-2010 |
20100190034 | SURFACE TREATMENT, SURFACE-TREATED HEAD SLIDER OR MAGNETIC RECORDING MEDIUM, AND MAGNETIC RECORDING-REPRODUCING DEVICE - A novel technology for lowering the surface free energy is provided. A treatment surface is irradiated with ultraviolet light in a gas containing a fluorine-containing organic substance, thereby forming a coating layer on the treatment surface. | 07-29-2010 |
20100211735 | STORAGE SYSTEM, STORAGE CONTROL DEVICE, RECEPTION CONTROL DEVICE, AND CONTROL METHOD - A storage system, including a storing unit, which is configured to be connectable to an information processor, includes a communication data receiving unit, a path information extracting unit, a specifying information creating unit and an access controlling unit. The communication data receiving unit receives communication data transmitted from the information processor. The path information extracting unit extracts path information indicating a communication path between the information processor and the communication data receiving unit, from the communication data received by the communication data receiving unit. The specifying information creating unit creates specifying information indicating the information processor that is the transmission source of the communication data, based on the path information extracted by the path information extracting unit. The access controlling unit performs an access control on the storing unit corresponding to the communication data, based on the specifying information created by the specifying information creating unit. | 08-19-2010 |
20100232071 | PERPENDICULAR MAGNETIC RECORDING MEDIUM, METHOD OF MANUFACTURING THE SAME, AND MAGNETIC RECORDING/PLAYBACK APPARATUS - According to one embodiment, a magnetic head includes a slider, a recording/reproduction element formed on a distal end face of the slider, and a resin film formed at least on the recording/reproduction element and the distal end face and having at least one of water repellency and oil repellency. | 09-16-2010 |
20100316814 | FILM DEPOSITION APPARATUS AND FILM DEPOSITION METHOD - A film deposition apparatus includes: a plasma generating section configured to generate plasma between a cathode target and an anode; a film deposition chamber in which a base material is placed; and a magnetic-field filter section configured to remove a particle from the plasma by a magnetic field and to transfer the plasma to the film deposition chamber. The magnetic-field filter section includes: a first housing area to which a first voltage is applied; and a second housing area, provided downstream of the first housing area in the moving direction of the plasma, to which a second voltage is applied. | 12-16-2010 |
