摘要
To realize higher storage density on a magnetooptical disk, we proposed the write control method, which controls shapes of recorded mark in marks length recording. In this paper, the analysis of this write control method is reported. Based on the model of the recording process, we discuss the necessary condition of the recording pulse waveform for the control of the recorded mark shape on magnetooptical recording media which have large heat conductivity. The write control method is examined under the condition of 880 Mb/in2 recording density. The precise control of the recording mark shape is confirmed through the experiment. From the result of the computer simulation, it is proven that this method satisfies the necessary condition, which clarified the effect of this method theoretically.
