PURPOSE:To obtain a durable recording head, by providing a magnetic driving part, the clapper striking a wire by excitation and the buffer part which absorbs the returning impact of the clapper and at the same time, lowers noise by effectively absorbing transient damping oscillation. CONSTITUTION:When the clapper 110 striking a wire with the magnetic driving part excited according to a recording signal returns, the transient damping oscillation is effectively absorbed with the stopper 134 of plate butyl rubber or the like. However, the stopper 134 is lined with a metallic reinforcing plate 135 for reinforcing it and further all the stopper 134 is held by elasticity with the spring washer 138 functioning as a pressing component. Thus, the impact is received with the rubber at first and this impact is spread on the surface. Then, this force is received with the washer. Therefore, the oscillation can be stably absorbed. |
