PURPOSE:To provide a recording apparatus having a recording head easy to highly densify a recording electrode, low in cost and having high quality and high reliability, constituted by connecting the recording electrode patterns constituted on a rigid substrate to a voltage pulse applying circuit through a flexible circuit board. CONSTITUTION:A recording electrode is constituted of recording patterns 20 formed on the non-magnetic insulating rigid substrate 19 mounted to the outer peripheral surface of a hollow body 11. The recording electrode patterns 20 are connected to a voltage pulse applying circuit 28 through a flexible circuit board 22 and the rigid substrate 19 is received in the magnetic field due to a magnet roll 12 along with the hollow body 11. The arrangement of the voltage pulse applying circuit 28 relative to a recording head 18 can be freely selected without generating problems in the arrangement linearity of the electrode patterns 20 or the preciseness of arrangement pitches. |
