Abstract
A laser recorder capable of recording a picture having halftones with densities of more than several tens of levels. An input video signal is sampled with a sampling pulse in response to which a number of high frequency pulses are applied to a beam source with the frequency of the high frequency pulse signal being higher by these two orders of magnitude than the frequency of the sampling pulse signal. The phase of the sampling pulse signal is alternated between adjacent scanning lines to thereby improve the number of available halftone densities.
