Claim:
1. A dot recording apparatus comprising: a recording head that includes a plurality of nozzles; a main scanning driving mechanism that performs a main scanning pass for forming dots on a recording medium while relatively moving the recording head and the recording medium in a main scanning direction; a sub-scanning driving mechanism that performs sub-scanning for relatively moving the recording medium and the recording head in a sub-scanning direction that intersects the main scanning direction; and a control unit, the control unit performing multi-pass recording in which dot recording on a main scanning line is completed by N main scanning passes (N is a predetermined integer of 2 or greater), and the control unit controlling the recording head to perform dot recording in the N main scanning passes using a plurality of super cell regions that include m types (m is an integer of 2 or greater) of super cell regions having different sizes such that the super cell regions are formed as one dot group by some of the plurality of nozzles, and the control unit controlling the recording head to form, among the m types of the super cell regions, at least one type super cell regions during one of the N main scanning passes such that each of the at least one type super cell regions is formed by a plurality of the dots and has a plurality of boundary line portions dividing the each of at least one type super cell regions from adjacent super cell regions that are adjacent to the each of at least one type super cell regions and all of the boundary line portions of each of the at least one type super cell regions are not parallel to the main scanning direction and the sub-scanning direction.
