摘要： An information recording/reproducing device and a medium are improved in reliability by making medium managing information usable even when a defective sector exists in the medium managing information area of the medium. The identifier of medium managing information, the information about the position where the medium managing information is recorded which is the information about the position of the sector in use, or the information about the position where a defect exists in the medium managing information area which is the information about the position of the defective sector are read from the medium managing information area of the medium (3) and all the information is stored in a RAM (8) by means of a medium managing information position managing means (5). A reproducing means (1) and a recording means (2) are controlled based on the information. Therefore, the medium managing information is correctly recorded and the reliability of the data of the information recording/reproducing device and the medium is improved, because the medium managing information is not recorded in the defective section.

摘要： A magneto-optical storage for recording data onto a magneto-optical recording medium. The magneto-optical recording film (43) is irradiated with a first light spot (61) of a small diameter, and with a second light spot (62) having a large diameter and concentric with the first spot. The temperature around the recording position is changed between room temperature (TROOM) and a temperature higher than a compensation temperature (TCOMP) of the recording film (43) due to the irradiation with the second light spot (62), and the intensity of the first light spot (61) is modified depending upon the data to elevate the temperature at the recording position near the Curie point (Tc) of the recording film (43), in order to erase the old data that have been recorded and to write new data.
摘要翻译：一种用于将数据记录到磁光记录介质上的磁光存储器。用小直径的第一光点（61）和具有大直径的第二光点（62）和与第一光斑同心的第一光点（62）照射磁光记录膜（43）。记录位置周围的温度由于第二光点（62）的照射而在室温（TROOM）和高于记录膜（43）的补偿温度（TCOMP）的温度之间改变，取决于提高记录膜（43）的居里点（Tc）附近的记录位置处的温度的数据来修改第一光点（61），以便擦除已经记录的旧数据并写入新的数据。
