摘要：
The dimensions/shape of ink flow channels in a recording head are designed so that when the inertance of nozzles is represented by Mn, the inertance of the ink supply channels is represented by Ms, the combined resistance obtained by combining the flow channel resistance in the nozzles, the flow channel resistance in pressure chambers, and the flow channel resistance in the supply channels is represented by R, and a unique vibration cycle of the pressure fluctuation arising in the ink within the pressure chambers is represented by Tc, the following Equation (A) holds true. √{square root over (MnMs)}≦RTc (A)
