A recording apparatus including: (a) a recording head unit for forming a recording operation with recording materials; (b) a main circuit for outputting drive waveform signal sets each including drive waveform signals; and (c) a head driver unit for receiving each drive waveform signal set, generating a drive signal based on one of the drive waveform signals that is selected among each received drive waveform signal set, and supplying the drive signal to each actuators of the recording head unit. The main circuit is connected to the head driver unit through signal wires that transmit the drive waveform signals of the drive waveform signal sets. The signal wires include common signal wires each transmitting one of the drive waveform signals of one of the drive waveform signal sets that controls ejection of one of the recording materials used in a first recording mode, and also one of the drive waveform signals of one of the drive waveform signal sets that controls ejection of one of the other recording materials used in a second recording mode.
