To efficiently execute a recording processing including a recording data converting processing such as HV converting without preparing an additional memory which stores next data for driving a recording head.

Recording data HV-converted by an HV converting circuit 20 are stored by a recording data storing means 30 in a memory 22 for every recording action by one scanning of the recording head 1 using one addressing pattern of a plurality of addressing patterns. And, the recording data are read out by a recording data reading means 31 using the addressing pattern selected when storing the recording data, and succeeding recording data are stored in a memory area of a memory means where recording has been already completed even if the recording head 1 is scanning.
