摘要： A capacitance detecting apparatus which can detect the change in minute capacitance of a measuring object with high sensitivity comprises a signal generator, a differential amplifying circuit, and a detecting unit. The signal generator generates a probe signal w(t) to be applied to one end of the measuring object. The differential amplifying circuit amplifies differentially a response signal v1(t) developed at the other end of the measuring object in response to the application of the probe signal w(t) and the probe signal w(t). The detecting unit detects capacitance change of the measuring object based on the amplified signal v(t) from the differential amplifying circuit.

摘要： Optical disk information recording apparatus and reproducing apparatus are designed to efficiently improve the transfer rate in information recording and reproduction, and have compatibility with the existing recording apparatus and reproducing apparatus using a single light beam while keeping the disk form with a single spiral track structure. Beam spots are simultaneously irradiated on a plurality of different radial positions on a disk at a pitch of a predetermined number of tracks to independently record various information signals, and the optical head is allowed to jump over a predetermined number of tracks every time the disk makes a predetermined number of turns. Another feature lies in that beam spots are simultaneously irradiated on a plurality of different radial positions on a disk at a pitch of a predetermined number of tracks to independently record various information signals, and a jump over a predetermined number of tracks is made in a predetermined interval corresponding to a period from the point where each light beam has made a track jump during which period signals are stably reproducible or recordable.

摘要： In a two-dimensional probe array, an interval between the leading ends of probes adjacent to each other in an X direction is made shorter than that between the leading ends of probes adjacent to each other in a Y direction. Thus, the leading ends of the probes are arranged to form a lattice wherein many rectangles are arranged. Furthermore, the lowest resonance frequency of an actuator which moves a recording medium in the X direction is set higher than the lowest resonance frequency of an actuator which moves the recording medium in the Y direction. At the time of recording or reading information, the recording medium is reciprocated in the X direction at a frequency substantially equal to the lowest resonance frequency of the actuator.
