发明名称 A recording apparatus using magneto-optical effect.
摘要 <p>This invention relates to a recording apparatus using magneto-optical effect in which information is recorded on a magneto-optical disc (1) and, more particularly, to a recording apparatus using magneto-optical effect of the magnetic field modulating type in which a light beam is irradiated onto a magneto-optical disc (1) and a magnetic field modulated by a predetermined modulating method is applied to the magneto-optical disc (1). The light beam is irradiated intermittently onto the magneto-optical disc (1) by drive pulses (LP) based on reference clocks (Sck) and the drive pulses (LP) at the positions corresponding to change points of information thinned out in the case where a ratio N of the minimum length between transition to the window margin is larger than 1, thereby accomplishing recording of a correct magnetization pattern.</p>
