Abstract: A data recording method is provided to rapidly record data by switching a domain of a ferroelectric film because a heat supplied to the ferroelectric film lowers a coercive field. The method includes a step of supplying a heat and an electric field on a data recording zone on a ferroelectric film of a recording medium by supplying an electric voltage for a resistive probe(40) and a lower electrode(50). A voltage(Vr) is supplied for a portion of the resistive probe(40) near the ferroelectric film of the recording medium, a voltage(V3) is supplied for the lower electrode(50) and the voltages, V3 and Vr, satisfy an inequality V3-Vr > Vc where the Vc is a coercive voltage needed in reversing a remanent polarization of the ferroelectric film.

The second driving units are spaced apart upward from the substrate, and driven in a second direction, in each of the regions formed in the vicinity of sides of the second direction. The stage is disposed over the second driving units such that the stage is driven in the second direction. The third driving unit is spaced apart from the stage and the anchor unit, and extended from both sides of the first driving units into a single body such that the third driving unit drives the stage in the first direction when the first driving units are driven in the first direction. The first direction transform spring unit is arranged such that the first driving units are supported at an inner surface of the anchor unit and the first driving units are transformable in the first direction. The second direction transform spring unit is arranged such that the second driving units are supported at an inner surface of the third driving unit and the second driving units are transformable in the second direction.

Abstract: An RF power sensor for measuring power for an RF signal using capacitance includes a substrate preferably formed of a semiconductor, such as silicon or of a dielectric substance, a fixture part fixed to the substrate and forming a signal line and ground lines that transmit RF signals, and a bridge connected to the ground lines and floating over the signal line, wherein the bridge is driven by an external driving force, and the external driving force induces capacitance between the bridge and the signal line. Accordingly, power for an RF signal can be measured through the capacitance between the signal line and the bridge. The RF power sensor facilitates matchings, reduces insertion loss, and can be used in a wide bandwidth because it is based on transmission lines having characteristic impedance. Further, high power can be measured depending upon bridge designs.

Abstract: The apparatus includes a first gain adjuster, a second gain adjuster, an amplifier, a demodulator, a controller, and a change measuring unit. The first gain adjuster adjusts the gain of an input signal and outputs the gain-adjusted input signal as a first modulating signal, while the second gain adjuster adjusts the gain of an inverted input signal and outputs the gain-adjusted inverted input signal as a second modulating signal. The amplifier amplifies a modulated signal output from a junction between the first and second capacitors and outputs the amplified results. The demodulator demodulates the amplified results received from the amplifier in response to a control signal and outputs the demodulated result. The controller generates the control signal per unit period of the input signal and outputs the generated control signal to the demodulator. The change measuring unit measures the change in capacitance from the demodulated results received from the demodulator. An offset produced by parasitic capacitance is compensated without affecting the change in capacitance to be measured.
