摘　　要：对磁光盘的接口标准SCSI进行了分析的基础上,提出了用DOS中断4B和4F来进行磁光盘驱动器中光学头的逻辑道定位.同时,在分析5X密度磁光盘标准ISOIECDIS15041:1996(E)的基础上,提出了逻辑道和物理道的对应关系.这为磁光盘的跨道信号。The MO disk interface standard SCSI Ⅱ is analyzed and a new method proposed to locate the logical track of the opto head of MO driver by DOS interrupter 4B. It neednt dissect the controller of MO driver and analyze the driver program of MO disk driver by the unmasm method. It can locate the opto head of MO driver in the logical track and is convenient and reliable. The 5X density magneto optical disk standard ISO/IEC DIS 15041: 1996 (E) is analyzed and the correspondence of logical channel and physical track is proposed which paves the way of testing tracking signal, groove signal and header signal.
