ABSTRACT:
A recording apparatus includes a recording head and a drive circuit for driving the recording head. The recording head includes a plurality of main blocks arranged successively in a given direction and a plurality of first and second conductors. The main blocks each include first and second unit recording blocks arranged in the given direction. Each unit recording block includes n recording units arranged in the given direction. One ends of the n recording units are collectively connected to the selection terminal of each unit recording block. The first conductors each connect the other end of the ith (n.gtoreq.i.gtoreq.1) of the first recording block with the other end of the (n+1-i)th recording unit of the second unit recording block. The second conductors connect the corresponding first conductors in the respective main blocks and bears thereon signals to be recorded. The drive circuit includes first means for selecting a desired one of the unit recording blocks and second means for supplying recording signals to the recording units of the selected unit recording block in the order of the given directional order.
