Inkjet recording apparatus and recording method

An inkjet recording apparatus comprising:

• a head configured to eject ink onto a recording medium;
• a conveyor configured to convey the recording medium in a first direction;
• a carriage on which the head is mounted, the carriage being configured to reciprocate in a second direction perpendicular to the first direction;
• a motor configured to drive the carriage to reciprocate in the second direction such that the head moves relative to the recording medium while facing the recording medium;
• a memory;
• and
• a controller configured to:
• determine, based on image data stored in the memory, whether both a code image and a non-code image are included in an image to be recorded in a passing region of the recording medium, the passing region being a region through which the head passes due to a relative movement of the head, the code image being formed by a plurality of recorded regions and a plurality of non-recorded regions, the non-code image being an image other than the code image;
• and
• in response to determining that both the code image and the non-code image are included in the image,
• during a first relative movement of the head, perform first separate recording processing of controlling the head and the motor to record at least part of a portion of the code image included in the passing region without recording a portion of the non-code image included in the passing region;
• and
• during a second relative movement of the head which is performed after the first relative movement, perform second separate recording processing of controlling the head and the motor to record at least part of the portion of the non-code image included in the passing region without recording the portion of the code image included in the passing region.
