According to an embodiment of the invention, a load estimation apparatus which estimates a load added to a laser light irradiation apparatus is provided. In the load estimation apparatus, a focal length adjustment unit adjusts the focal length in accordance with a distance from a light source to a light irradiation position in a recording medium, the apparatus comprising: an obtaining unit which obtains control data in which the light irradiation position is instructed with a coordinate; an operation amount detection unit which analyzes the coordinate of the control data to detect an operation amount of the focal distance adjustment unit; a load value calculation unit which accumulates load value information of the focal length adjustment unit in response to results of comparing the threshold and the operation amount when the operation amount is detected.
