摘要： A method for simply and efficiently separating substances by utilizing a specific flow behavior in a non-turbulent flow, i.e. a laminar flow, in a micro-channel is disclosed. A mixed solution containing at least two kinds of solute molecules which are different from each other in molecular weight and/or molecular sharp, or at least two kinds of solutions containing their respective solute molecules are flowed into a micro-channel to form a non-turbulent flow. A physical action is given to each molecule by changing the state of flow, thereby causing different behaviors among the different solute molecules. By utilizing this behavior difference, molecules of a specific kind are gathered in a specific region in the channel for separation.

摘要： Embodiments of the invention prevent a decrease in magnetization or demagnetization from occurring to recording magnetization regardless of a direction in which a stray field is applied. In one embodiment, an apparatus for data storage system comprises a head having a magnetic field shield in the vicinity of a main pole, and a cover of the device, using a constituent material with a magnetic field shielding effect, across the cover, or at part thereof. When a stray field in a direction perpendicular to a recording medium is applied, the effect of the magnetic field is alleviated by the magnetic field shield installed in the vicinity of the main pole. In such a case, it need only be sufficient to form the magnetic field shield in a shape optimum for removing the stray field in the perpendicular direction only. When a stray field in a direction horizontal in relation to the recording medium is applied, the magnetic field acting on the recording medium is removed by the cover of the device comprising a magnetic component.

摘要： Embodiments of the invention reduce generation of a magnetic field with a polarity reverse to that of the recording magnetic field, without deteriorating a gradient in the magnetic field. An embodiment of a magnetic disk device according to the present invention suppresses deviation and erase of already recorded data. In an embodiment, the perpendicular magnetic recording head includes the main magnetic pole, an auxiliary magnetic pole, a trailing shield disposed on the trailing side of the main magnetic pole with a non-magnetic film placed in-between, and side shields disposed on both the sides of the main magnetic pole in the direction of the track width with a non-magnetic film placed in-between. The trailing shield has on the trailing side a portion where film thickness is thinner on the trailing side than the thickness of its element in the height direction in its position facing the main magnetic pole. Adoption of this configuration allows suppression of generation of the magnetic field having a polarity reverse to that of the recording magnetic field, without deteriorating the magnetic field gradient. Also in the portion where the side shields face the main magnetic pole, the side shields have the portion where the film is thinned down in thickness.
