    摘要： Embodiments of the present invention relate disk drives, and in particular to realizing a positioning accuracy equal to that of an actuator having the mountable maximum number of suspensions, in an actuator having the smaller number of suspensions than the mountable maximum number. An embodiment of a magnetic disk device includes an actuator having an arm to which a suspension for applying a predetermined load onto a slider with a magnetic head is attached, and an arm to which a plate is attached instead of having the suspension. The plate attached to the arm in place of the suspension has a partially small section with respect to a section perpendicular to an arm longitudinal direction (constricted part), and the constricted part is located between a plate leading end and an arm attachment part.

    摘要： The RF power amplifier includes first and second amplifiers Q1 and Q2 as final-stage amplification power devices connected in parallel between an input terminal RF_In and an output terminal RF_Out. The amplifiers Q1 and Q2 are formed on one semiconductor chip. The first bias voltage Vg1 of the amplifier Q1 is set to be higher than the second bias voltage Vg2 of the amplifier Q2 so that the amplifier Q1 is operational between Class B and AB, and Q2 is operational in Class C. The first effective device size Wgq1 of the amplifier Q1 is intentionally set to be smaller than the second effective device size Wgq2 of the amplifier Q2 beyond a range of a manufacturing error of the semiconductor chip. An RF power amplifier that exhibits a high power-added efficiency characteristic regardless of whether the output power is High or Low can be materialized.
