28 ABSTRACT An magneto-optic data recording system whereby multi-channel analog signals can be recorded and reproduced and data can be retrieved at high speed. The multi-channel analog signals received by an analog signal input terminal (1) are filter-processed, converted into digital values by an A/D converter (4) and temporarily stored in a RAM (6). The signals thus temporarily stored are recorded in a recording data section of a specific sector on an magneto-optic disk (12). During the recording, ID numbers, real time information such as record starting time and record stopping time, event information and trigger information and the like are also recorded in a condition data section of the above- described sector as a retrieval index. When retrieving data, index information in the condition data sections of the magneto-optic disk (12) is used.
