ABSTRACT:
A laser recorder using a semiconductor laser which is capable of reproducing an image such as a picture having half-tones with a high quality. An input signal is sampled with pulses from a timing processing circuit and converted using a read-only memory into pulse numbers and a corresponding positive-negative pulse identifying bit. The output of the read-only memory is compared with the output of a counter to thereby apply pulses to a laser oscillator in a number and with a polarity specified by the output number from the read-only memory.
