摘要:
It is an object of the present invention to provide a high density magneto-optical recording/reproducing apparatus and a high density magneto-optical recording/reproducing method for recording a mark on a recording medium in a manner such that an edge position of a mark reproduced from the recording medium may not be varied. The magneto-optical recording/reproducing apparatus for recording/reproducing an information mark on/from a magneto-optical recording medium includes means for determining the length of a first recording information mark and means for adjusting the intensity of a recording magnetic field for recording a second information mark depending on the length of the first information mark recorded immediately before the second recording information mark.
摘要(中):
本发明的一个目的是提供一种高密度磁光记录/再现装置和用于在记录介质上以标记的边缘位置记录标记的高密度磁光记录/再现方法 从记录介质再现的可能不会改变。 用于在磁光记录介质上记录/再生信息标记的磁光记录/重放装置包括用于确定第一记录信息标记的长度的装置和用于调节记录磁场的强度的装置 第二信息标记取决于紧接在第二记录信息标记之前记录的第一信息标记的长度。
