ABSTRACT:
There is established a process of writing line data into and reading line data from line buffers when a film which is being fed in an auxiliary scanning direction is scanned in a main scanning direction in an interlaced scanning fashion with n recording beams that are emitted from an acoustooptic modulator based on simultaneously supplied n line data. It is assumed that the n line data transferred to channels CH1-CHn of the acoustooptic modulator have respective sequential numbers N (N=1-n). If the line data in a channel CHN exposed in a preceding scanning cycle is stored in any of the line buffers, then the line data of a sequential number N is written into that line buffer. If there is no line data in a channel CHN exposed in a preceding scanning cycle, then the line data of a sequential number N is written into a line buffer according to its sequence by referring to a write sequence table. The n line data are simultaneously read from the line buffers according to a read sequence table and transferred to the channels CH1-CHn of the acoustooptic modulator.
