Abstract
An apparatus for ion recording using an apparatus for generating ions which can be operated by a low signal voltage. The corona ions are controlled either by imposing the low signal voltage which changes the voltage level of the corona ion generation section above and below the critical voltage for corona ion generation, or by controlling the flows of constantly generated corona ions using the low signal voltage which changes the relative voltage level of the corona ion generation section in order to turn the flows of corona ions on and off.
