ABSTRACT:
An information recording method in which a recording start position of a data section in which file data of a recording medium such as an optical card has been recorded is calculated on the basis of a directory for managing a file of the information recording medium recorded in a directory section and, when the data has been recorded at the calculated recording start position, a retry operation to judge whether the data has been recorded at the next recording position or not is repeated a predetermined number of times, thereby retrieving the final recording position of the data section. When the final recording position of the data section cannot be detected even if the retry operation was repeated the predetermined number of times, the information indicative of the recording position at which the retry operation was finally executed is recorded to the directory section. When performing the retry operation again, the retry operation is executed from the recording position at which the retry operation was finally performed on the basis of the information indicative of the recording position at which the retry operation was finally executed.
