Abstract

PURPOSE: To obtain a recording head having a small extension of the recording dots without missing any recording dot, by interposing the ohmic electrode having an insulating layer of specified thickness and a given resistance value between the recording stylus electrode and the limiting electrode.
CONSTITUTION: Recording stylus electrode 1 is covered with insulating layer 5 having the thickness not more than 1W100μm of polyurethane, and in the circumference, resistant means 6 having the relative resistance not less than 103Ωcm is provided, which is formed using epoxy resin dispersed with the conductive inorganic pigment such as carbon, and in adjacent to this, limitting electrode 7 is formed. When the application of negative recording voltage VN to recording electrode 1 and the application of positive limiting voltage Vc to the limiting voltage 7 are carried out simultaneously, a partial discharge occurs inside a fine space between the recording stylus electrode 1 and the resistant means 6, with this discharge being used as a trigger to create a definite discharge between dielectric layer 10 charged to positive electric potential VF theretofore and the recording stylus electrode 1 applied with voltage VN, thus to permit the recording without missing any recording dot.
