摘要： Embodiments of the invention efficiently improve the stray field robustness without changing the size or weight of the drive on a large scale. Because a stray field concentrates on a magnetic field element, a symptom in which already recorded data is erased is prevented. According to one embodiment, in a magnetic recording system that uses a perpendicular recording medium having a soft magnetic under layer, a soft magnetic shield is provided on an upper part and a side of a slider on which a magnetic head is mounted, and a distance C between the shield and the medium is made smaller than a distance A or B between the shield and the slider.

摘要： Power amplifier circuits which constitute an RF power module used for a digital device capable of handling high frequency signals in two frequency bands are disposed over the same IC chip. The power amplifier circuits are disposed around the IC chip, and a secondary circuit is disposed between the power amplifier circuits. Thus, the power amplifier circuits are provided within the same IC chip to enable a size reduction. Further, the distance between the power amplifier circuits is ensured even if the power amplifier circuits are provided within the same IC chip. It is therefore possible to suppress the coupling between the power amplifier circuits and restrain crosstalk between the power amplifier circuits.

摘要： A magnetic disk unit includes a magnetic disk attached to a spindle so as to be rotatable, a slider having a magnetic head for reading/writing data onto/from the magnetic disk, a suspension for providing the slider with a predetermined load, and an actuator arm for positioning the slider attached to the suspension on the magnetic disk. A first pad including the magnetic head and second pads including no magnetic heads are disposed on an air bearing surface of the slider. During rotation of said magnetic disk, a part of the first pad keeps in contact with the magnetic disk. A load point of the suspension with respect to the slider is positioned between a leading edge of the slider and a position located at a distance equivalent to substantially 0.42 times a whole length of the slider from the leading edge of the slider.

摘要： When a slider slides on a recording medium and a frictional force acts on the slider, an unstable vibration resulting from falling forward of the slider and a local stress are prevented from being generated. An attitude of the slider is stabilized, and the slider is kept in a steady contact with a disc. A rotary support mechanism is constituted by successively connecting one deformable portion, one rigid portion and another deformable portion to an upstream side of another rigid portion with a slider attached thereto in a recording medium movement direction. The another deformable portion is bonded to a support arm. While a predetermined pressing load is given to the slider by a spring portion, an intersection of an extension of a virtual line connecting the one and another deformable portions with the surface of the recording medium is positioned on the upstream side of a sliding point of the slider on the recording medium in the recording medium movement direction.

Moreover, a reference voltage generating circuit is additionally provided to establish upper and lower reference voltages of a second flash-type A/D converter for determining lower significant bits on the basis of the step voltage of the DAC output.
