ABSTRACT:
A vertical line deflection, mirror 8 in a laser COM is driven by a staircase waveform generated in response to scan line synchronizing signals. To avoid data character compression or expansion following a stop or data line skipping operation due to the mirror inertia, video signal generation is delayed for several scan lines following such an operation to allow the mirror to reach a constant rotational speed.
