Description of the Related Art A current transfer type recording device (current transfer type printer) has a recording electrode and a return electrode in contact with an ink film having an ink layer and a resistance layer, and a current is passed from the recording electrode to the return electrode via the resistance layer. By flowing the ink, the resistive layer generates heat, and the ink layer of the ink film is transferred to the recording paper as dots by the heat generated. When performing gradation control in this type of conventional current transfer type recording device, the number of energization times (the number of energization pulses) for the dots to be recorded is controlled according to the gradation data, and the energization time is controlled. Gradation control was performed by controlling the amount of heat generated by the resistance layer, that is, the amount of heat applied to the ink layer. That is, the recording data transferred to the current-carrying recording head includes gradation data, and the gradation is controlled by digital processing. If the amount of heating to the ink layer is large, a large amount of ink will be transferred to the recording paper, resulting in a high density. If the amount of heating is small, the amount of ink transferred to the recording paper will be small, resulting in a low density.

。[Operation] In the current transfer type recording method or apparatus having the above structure, when the ink film is irradiated with light, the resistance value of the resistance layer of the ink film changes depending on the amount of the irradiated light. When the amount of light irradiated onto the ink film is set according to the gradation data of the dots to be recorded, and a voltage with a constant pulse width is applied between the recording electrode and the return electrode, the current flowing through the resistance layer is blocked by the amount of irradiated light. It changes according to the gradation data to be recorded, and the amount of heat generated, that is, the amount of heating to the ink layer is controlled, and gradation control is performed. In this way, gradation control is performed using analog control that controls the amount of light irradiated onto the ink film, and since it is only necessary to apply a voltage with a constant pulse width to the current-carrying recording head, there is no gradation in the recorded data transferred to the current-carrying recording head. Compared to the case where tone data is included and tone control is performed by digital processing, data transfer processing to the energized recording head is significantly simplified.
