<p>An optical disk apparatus which can smoothly perform reproducing processing includes a detection unit (54), a fore-control unit (61), and a post-control unit (62). The detection unit detects information in VOBU (video object unit) which includes NV_PCK (navigation pack) and contents information in a plurality of chapters. The fore-control unit obtains one VOBU according to a reproducing direction, and writes absence of an address in a reserve area of NV_PCK to store the absence of the address with the contents information in a buffer when an address according to a current reproducing magnification is absent in NV_PCK. The post-control unit reads out NV_PCK, and recognizes NV_PCK as an end position of the chapter to direct readout of the next chapter to the fore-control unit when the address is absent.</p> |
