    • A recording head and apparatus with an element substrate having a reduced area are provided. A plurality of recording elements for generating energy to discharge liquid are divided into a plurality of blocks Grp1 to GrpM. A first input circuit inputs a series of data signals and outputs the data signals to the plurality of blocks. The first input circuit is divided in correspondence to the blocks. A second input circuit inputs encoded block signals and outputs the block signals to the block. A plurality of output circuits drive drive circuits in accordance with the data signals from the first input circuit and the block signals from the second input circuit. The plurality of drive circuits supply currents to the recording elements and drive them.
