A recording apparatus has a recording head with a data generating unit that converts information transmitted from an external device into recording data that matches the configuration of the recording head for recording by the recording head. The recording apparatus has a first power supply circuit for supplying drive power to a drive element that drives by the nozzles of the recording head and a second power supply circuit that drives the heating elements that control recording by the nozzles. As a result, the recording apparatus can provide stable recording, unaffected by any voltage drop in the circuitry that drives the recording head.
