1. A recording method that performs recording on a recording medium, the recording method comprising:
a white ink adhesion step of adhering a white ink composition containing a white color material to the recording medium; and
a non-white ink adhesion step of adhering a non-white ink composition containing a non-white color material to the recording medium,
wherein the white ink adhesion step and the non-white ink adhesion step are performed by relative scanning between a recording head and the recording medium,
the white ink adhesion step and the non-white ink adhesion step are performed by the relative scanning that is same as each other on a same scanning region of the recording medium,
in a recording region to which the white ink composition and the non-white ink composition are adhered, an adhesion amount of the white ink composition is 60% by mass or less with respect to 100% by mass of an adhesion amount of the non-white ink composition per unit region, and in the recording region to which the white ink composition and the non-white ink composition are adhered, a maximum adhesion amount of the white ink composition is 1.5 mg/inch2 or less, and
the recording head includes a white ink nozzle row and a non-white ink nozzle row that each extend along a direction that intersects a scanning direction of the recording head, the white ink nozzle row has a white ink ejection nozzle row for ejecting the white ink composition at a time of recording, and the non-white ink nozzle row has a non-white ink ejection nozzle row for ejecting the non-white ink composition at the time of recording,
when the white ink nozzle row and the non-white ink nozzle row are projected along the scanning direction, the white ink ejection nozzle row has a portion that overlaps the non-white ink ejection nozzle row in the direction that intersects the scanning direction of the recording head such that the white ink composition overlaps the non-white ink composition by a same scanning on a same scanning region of the recording medium, and
the scanning is conducted by moving a carriage to which the ink jet head is mounted.
