Abstract
Graphic signals and literal (or drawing) signals are recorded substantially simultaneously by increasing or decreasing the number of beam components output from at least one of a literal head and a graphic head after a specified number of scanning lines, both of which heads are being synchronously fed in the sub-scanning direction. Variation of the number of beam components used in the head is used to change the scan length of the head, for synchronizing the feed pitch therefor with the feed pitch of the other head when the scan lengths of the two are not integrally related. Differences between the feed pitch and the scan length of the variable scan length recording head are corrected by slight adjustments of the head position in the sub-scanning direction.
