Abstract
PURPOSE: To achieve the improvement in resolution and recording quality without increasing the density of heads by moving a mutistylus head through the utilization of 1 or 2 bits of the output signal of an A/D converter.
CONSTITUTION: The analog signal applied to input terminal 1 is converted to the digital signal of n bits by an A/D converter 2 and the minimum bit thereof is applied to a head moving command circuit 6 and the remaining n-1 bits are applied to a decoder 3, respectively. The decoder 3, recording head driving circuit 4 and multistylus head 5 perform recording by receiving the digital signal of n-1 bits. In addition, the head moving command circuit 6 moves the head 5 by 1/2 pitch by way of a head mover 7. The head 5 then performs the recording corresponding to the digital signal of n-1 bits in the moved state. In this way, the improvement in resolution and recording quality may be achieved without increasing the density of the heads.
