A dot recording apparatus comprising: a main scan driving mechanism (70, 71, 73) configured to execute a main scan pass, which records dots on a medium while relatively moving a recording head having a nozzle row that includes a plurality of nozzle groups (A-J), which are configured by a plurality of nozzles that are arranged in a direction that intersects a main scanning direction, and the medium in the main scanning direction; a sub-scan driving mechanism (74, 75) configured to execute a sub-scan, which relatively moves the medium and the recording head in a sub-scanning direction, which intersects the main scanning direction; an image sensor configured to capture an image of dots formed on the medium, the image sensor being supported by a carriage supporting said recording head; and a control section, wherein the control section is configured to execute a first formation that forms a first dot group using a first nozzle group, and a second formation that forms a second dot group in a position that differs from that of the first dot group in either the main scanning direction or the sub-scanning direction, using a second nozzle group, characterised by a third formation that forms a third dot group in which the position in the sub-scanning direction overlaps with at least a portion of the first dot group, using a third nozzle group, of which the distance from the first nozzle group in a direction of the nozzle row is a first nozzle row distance, a fourth formation that forms a fourth dot group in which the position in the sub-scanning direction overlaps with at least a portion of the second dot group, using a fourth nozzle group, of which the distance from the second nozzle group in a direction of the nozzle row is a second nozzle row distance, which differs from the first nozzle row distance, and a calculation of inclination of the recording head with respect to the main scanning direction on the medium based on a first distance in the main scanning direction from the first dot group up to the third dot group, and a second distance in the main scanning direction from the second dot group up to the fourth dot group, which are acquired using the image sensor. a main scan driving mechanism (70, 71, 73) configured to execute a main scan pass, which records dots on a medium while relatively moving a recording head having a nozzle row that includes a plurality of nozzle groups (A-J), which are configured by a plurality of nozzles that are arranged in a direction that intersects a main scanning direction, and the medium in the main scanning direction;
