Abstract
A recording system including a recording head with multistyli movable in linear reciprocatory movement crosswise of a recording medium which itself is movable in a direction at right angles to the direction of linear reciprocatory movement of the carriage, and a drive circuit for applying high potentials to the selected styli including a diode matrix connected to the multistyli, and line-direction drivers and row-direction drivers connected to line-direction conductors and row-direction conductors respectively of the matrix. The carriage supports, in addition to the recording head, the diode matrix and the line-direction drivers and/or the row-direction drivers, so that the electrostatic capacity between wires connecting the drivers to the multistyli can be reduced and recording can be performed at high speed.
