ABSTRACT:
A recording apparatus performs a recording operation with a recording head including a first nozzle array including first type nozzles that can discharge an ink according to first discharge characteristics and a second nozzle array including second type nozzles that can discharge an ink according to second discharge characteristics. Driving parameters required for driving different types of nozzles are separately stored in a built-in memory unit of the recording head and in an internal memory unit of the recording apparatus. The recording apparatus obtains driving parameters of the first type nozzles based on the information relating to the characteristics of the first type nozzles. The recording apparatus obtains driving parameters of the second type nozzles based on the information relating to the characteristics of the first type nozzles, and the information relating to differences in characteristics between the first type nozzles and the second type nozzles.
