A second mask layer is formed on the first mask layer using Ru or Cr. A resist pattern is formed on the second mask layer. A second mask pattern is formed by performing reactive ion etching with reactive gas containing oxygen on the second mask layer using the resist pattern. A first mask pattern is formed by performing reactive ion etching with reactive gas containing halogen gas on the first mask layer using the second mask pattern. A magnetic pattern is formed by performing reactive ion etching with reactive gas containing oxygen on the magnetic layer using the first mask pattern.

  • Patent number: 7815278
    Abstract: A detection unit to optically detect a discharge condition of a droplet is disclosed. The detection unit includes a light emitting element and a light receiving element disposed on opposite sides of an area through which a droplet discharged from a droplet-discharger passes. A diaphragm plate having an aperture and another diaphragm plate having at least two apertures arranged at a pitch in a discharge direction are respectively disposed near front surfaces of the two elements. When light emitted from the light emitting element passes through the apertures, two light beams are received by the light receiving element. When the droplet is discharged and passes in front of the apertures, the two light beams are blocked sequentially by the ink droplet, which causes the quantity of light received by the light receiving element to change, thereby inducing a change in an output from the light receiving element. Based on the change in the output, a discharge-condition of the droplet is determined.

  • Publication number: 20100059476
    Abstract: A method for manufacturing a magnetic storage medium that improves the flatness of the magnetic storage medium. A storage layer is formed on a substrate. Next, a resist mask is formed above the storage layer. Then, a pit is formed in the storage layer using the resist mask. Afterwards, a non-magnetic layer having a thickness that is in accordance with the depth of the pit is formed in the pit and above the resist mask. Subsequently, the resist mask and the non-magnetic layer formed above the resist mask are removed from the storage layer.

  • Publication number: 20100023926
    Abstract: A method of analyzing program source code prepared for a multithreading platform comprises analyzing a targeted source code set to extract a set of characteristic information for each wait operation; analyzing the targeted source code set to extract a set of characteristic information for each notification call to an application programming interface of the multithreading platform; identifying a one-way branching correspondence with a wait operation for each notification call by comparing the extracted set of characteristic information for the notification operation and the extracted set of characteristic information for each wait operation with a set of predefined asynchronous operation correspondence pattern information for notification and wait functions implemented by the application programming interface; extracting a set of information for each identified one-way branching correspondence; and storing the extracted set of information for each identified one-way branching correspondence in a data store.

  • Patent number: 7621616
    Abstract: A recording head includes an ink-discharging surface and nozzles. The ink-discharging surface is provided with ink-discharging ports of the nozzles. A light-emitting element and a light-receiving element are disposed opposite each other close to the ink-discharging surface. The light-receiving element outputs a detection signal. A reflector is provided on the ink-discharging surface and reflects light emitted from the light-emitting element toward the light-receiving element. One of the nozzles is driven and whether the nozzle discharges an ink drop is checked on the basis of change in the detection signal due to interception of the reflected light by the ink drop. If the nozzle discharges an ink drop, then whether the nozzle discharges the ink drop in an appropriate direction is checked on the basis of change in the detection signal due to interception of the direct light by the ink drop.
