PROBLEM TO BE SOLVED: To provide an optical disk, an optical disk recorder and an optical disk reproducing device which record mass still image data, realize retrieval on the basis of its recording time and suppress the data size of recording time information small. SOLUTION: N (where N is a positive integer of one or larger) number of still images is collectively grouped to minimized data quantity, with which the recording time of the still images is managed, and the recording time (F- RECTM) of the first recorded still image and the recording time (L-RECTM) of the last recorded still image are recorded as management information in each group.
