摘要:
Disclosed is a thermally assisted magnetic recording medium comprising a substrate, a plurality of underlayers formed on the substrate, and a magnetic layer which is formed on the underlayers and predominantly comprised of an alloy having a L10 structure, characterized in that at least one of the underlayers is predominantly comprised of MgO and comprises at least one kind of a metal element having a melting point of at least 2,000° C., such as Nb, Mo, Ru, Ta or W. The thermally assisted magnetic recording medium has magnetic crystal grains having uniform size in the magnetic layer, and has a narrow switching field distribution (SFD), and a magnetic recording storage provided with the thermally assisted magnetic recording medium exhibits a high SN ratio.

Disclosed is a thermally assisted magnetic recording medium comprising a substrate, a plurality of underlayers formed on the substrate, and a magnetic layer which is formed on the underlayers and predominantly comprised of an alloy having an L10 structure, characterized in that at least one of said underlayers is predominantly comprised of MgO and comprises at least one kind of an element having a free energy for oxidation of, per mol of oxygen, not higher than −120 kcal/mol·O2 at 1000° C. The element having the free energy for oxidation is preferably selected from Al, Si, Ti, V, Cr, Mn, Zr and B . The thermally assisted magnetic recording medium has a magnetic layer comprised of magnetic crystal grains with uniform diameters, and exhibiting a sufficiently weak exchange coupling between magnetic grains.

Relevant document data are retrieved from a document management server that stores document data in accordance with a user operation at a document management client. A content of the document data is shown to the user at the document management client so that the user can provide an instruction whether to execute an alteration prevention by an operation of the user. When an instruction to execute an alteration prevention is provided, alteration prevention processing is executed at the document management server.
摘要:
A charge control unit controls electricity charged to a piezo element, which is for actuating a backpressure control valve so as to control backpressure applied to a valve element for a fuel injection valve. The backpressure control valve is configured to start to decrease the backpressure to actuate the valve element to open an injection port of the fuel injection valve when voltage of the electricity exceeds a threshold. A charge unit increases the voltage by repeating increasing and decreasing a drive current, which is supplied to the piezo element, for multiple times for charging the piezo element. A switching unit alternates the increasing and the decreasing such that the voltage exceeds the threshold in an intermediate period in a middle of a specific increasing period among multiple increasing periods, in each of which the drive current increases.
摘要:
A distribution server distributes over a network, menu information that contains information for executing a job using a multifunction apparatus and information for identifying the job. The distribution server sets at least a portion of the information for executing the job using the multifunction apparatus as additional information added later to the menu information, and adds an input instruction to the menu information for executing additional information input using the multifunction apparatus. The multifunction apparatus that obtains the menu temporarily determines a portion of a fixed job for execution.
