Abstract: PROBLEM TO BE SOLVED: To make a part with lowered reliability because of a trouble clearly graspable by storing the position of abnormality occurrence of a tape into a nonvolatile memory when any abnormality occurs in a power source or owing to vibration to make detecting of the position, where a trouble occurs, possible. SOLUTION: It is detected whether abnormality occurs or not wing to a power source, vibration or the like during the recording. When the abnormality attributed to the power source, the vibration of the like is found, the position involved of a tape is taken in.
