た。 In the conventional example configured in this way, since the corona ion flow was controlled by the potential difference between the control electrodes 2 and 3, the control voltage could be low;
Although this had the advantage of having a margin of distance between the writing section and the dielectric layer 6, it had the disadvantage that the recording speed was slow due to the low corona ion density.

In this case, by setting b>a, the corona ion flow density can be increased by two times (b/a). As a result, it becomes possible to increase the recording speed. Then, the distance between the control electrodes 11 and 12 is set to d
If the ranges of b and d in these control electrodes 11 and 12 are 4a>b>1.5a, 2a>d>0.5a, the corona ion flow can be controlled without increasing the voltage required for control. Increased density is possible.
