PROBLEM TO BE SOLVED: To provide an information processor and an information processing method for achieving data recording processing to minimize the recording error of file system information or the like. SOLUTION: The information processor has two modes as information writing modes for an information recording medium, that is, a normal writing mode (a) for not executing the priority recording processing of the file system information and an immediate writing mode (b) for executing the priority recording processing of the file system information. The information processor selects the write mode according to preset conditions, and executes the sequential recording processing of the file system information. On the basis of, for example, at least either the count value of a data recording instruction frequency from the start of the normal writing mode or the value of a timer which measures an elapsed time from the start of the normal writing mode, the information processor executes a mode change and the sequential recording processing of the file system.
