Abstract

PURPOSE:To secure heating time required for obtaining a sufficient density without raising a voltage impressed on a recording head, by a method wherein at the time of high-speed recording, data for a line to be newly recorded are compared with data for a previously recorded line, followed by controlling. CONSTITUTION:A line data forming circuit 2 stores parallel data 10 in a recording period, forms original data 11 for one line in which intermediate values between a maximum and a minimum of the data are made to be black, and outputs the original data 11 in synchronism with a shift lock 12. The original data 11 are connected to one of the inputs of an AND gate 8. When the data for the first line are all white, all the recording data 14 outputted are white irrespectively of whether the other input of the AND gate 8, namely, the output of an inverter 7 is white or black. The inverted data 13 are transferred to a recording head driving cicuit 4, and are simultaneously inputted into a shift register 6. When transferring is completed, the driving circuit 4 is latched by a latch signal 15, and the data subsequently fed are compared with the original data 11.

Since lines are not recorded continuously, 1) o = ao (2l), and when all the recording heads 3 are driven in the same recording cycle, r is twice as much as the conventional method shown in Fig. 3. The recording pulse width can be given. Thereby, sufficient concentration can be ensured without increasing the applied voltage. Also,
Regarding the influence of this method on the recording waveform, since the recording density of the secondary run is set high compared to the size of the recording dot, the missing portion of the waveform is hardly noticeable.
