    Abstract: Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing. Such aspects comprise replacing currently non-magnetic components of devices, such as interlayers and overcoats with components and compositions comprising magnetic materials. Other aspects relate to magnetic seed layers deposited within a recording medium. Preferably, these aspects, embodied as methods, systems and/or components thereof reduce effective magnetic spacing without sacrificing physical spacing.

    Abstract: Data in tables with foreign key relationship is synchronized in batches employing a two-pass process during playback based on whether the foreign key constraint is a linear dependency, self-referencing, or cyclic. A separate table containing a primary key of records and database timestamp columns for change operations may also be used for batch synchronization in addition to or instead of adding database timestamp columns to existing tables.

    Abstract: A system and method for measuring and controlling stator winding temperature in an AC motor while idling is disclosed. The system includes a circuit having an input connectable to an AC source and an output connectable to an input terminal of a multi-phase AC motor. The circuit further includes a plurality of switching devices to control current flow and terminal voltages in the multi-phase AC motor and a controller connected to the circuit. The controller is configured to activate the plurality of switching devices to create a DC signal in an output of the motor control device corresponding to an input to the multi-phase AC motor, determine or estimate a stator winding resistance of the multi-phase AC motor based on the DC signal, and estimate a stator temperature from the stator winding resistance. Temperature can then be controlled and regulated by DC injection into the stator windings.

    Abstract: An apparatus includes a plurality of bilayer structures positioned adjacent to each other, each of the bilayer structures including a first layer of magnetic material having a first Curie temperature and a second layer of magnetic material positioned adjacent to the first layer, wherein the second layer has a second Curie temperature that is lower than the first Curie temperature, and magnetic grains of the first layer are unstable when the second layer of magnetic material is heated above the second Curie temperature. The recording temperature is reduced due to the smaller switching volume achieved by using vertically decoupled laminations at elevated temperatures.

    Abstract: An image processing unit executes an image process on a target image based on process-setting contents, and generates a processed image. An area extracting unit compares the processed image with the target image, and extracts a partial area of a predetermined size showing a notable effect of the image process executed on the target image, as a checking area. A checking-image display unit displays the processed image corresponding to the extracted checking area on a display unit, as a checking image for checking the process-setting contents of the image process.
