There is provided a semiconductor device for multiplexing across a plurality of shared InputOutput pins. With this construction, the recording medium reproducing apparatus can be provide at a less expensive cost which can reproduce a plurality of moving image information having the same time series in one image while appropriately changing the size of areas where the information is reproduced. The receiver receives a Clear to Send communication from the second PLC device. A first fluid dynamic journal bearing having a first bearing gap and a second fluid dynamic journal bearing having a second bearing gap are disposed between the first member and the second member. The optical wavelength cross connect includes multiple wavelength routing elements, which are optical components that selectively route wavelength components between one optical signal and multiple optical signals in either direction according to a configurable state.
