PURPOSE:To enable high speed recording without causing uneven records or ghosts, by dividing recording styli into 4 groups and circularly scanning every other groups adjacent to each other for electrostatic recording. CONSTITUTION:A plurality of recording styli 2 are controlled and driven according to recording signals in circulating scanning by recording styli voltage drive circuits 3a to 3d connected to control voltage drive circuits 4 and a plurality of control electrodes divided into 4 groups A to D. Sequence drive control in which groups A and C and groups B and D are coupled in order not to control the adjacent groups at the same time permits high speed electrostatic recording freed of uneven records or ghosts to be carried out without being affected by adjacent styli 2 in every other groups. |
