Abstract
In a thermal recording system wherein a linear array of elemental resistance electrodes is employed to record received data bits which are organized into data segments of equal bits, the resistance array is divided into a plurality of identical blocks (#1 to #64) corresponding to the data segments. Successively arranged resistance blocks are selected by a selector (42) in response to first and second write-command pulses supplied from pulse generators (22, 24) in synchronism with the receipt of each data segment to record black dots corresponding to the received data bits. The first and second write-command pulses are generated so that the period of each pulse partially overlaps the period of the other, whereby the preceding resistance block is selected simultaneously with the subsequent one after the corresponding data bits have been removed. After-effect currents are supplied to the preceding block to increase the image density of the recorded black dots while the recording of the subsequent data segment is in progress. The after-effect currents are not sufficient to heat up the resistance elements which correspond to white areas.
