<p>An apparatus for recording and reproducing still pictures on and from a disk according to the invention comprises a still picture recording and reproducing means for recording a still picture in a particular position of a still picture recording region according to the last recording position information recorded in a recording position information sector specified by a pointer sector read out from the disk, and a still picture recording position information recording and reproducing means which, while managing a plurality of recording position information sectors so as to prevent the recording frequency of a recording position information sector from exceeding the maximum recording frequency, updates the recording position information about said still picture and the recording frequency of said recording position information sector and records them in the same or different recording position information sector, and which, when the recording position information is recorded in said different recording position information sector, updates said pointer sector on the information which specifies this recording position information sector. Thus, this apparatus shortens the time for retrieval of a still picture recording region of a disk limited in recording frequency and improves the recording frequency of the disk and ensures a reliable recording operation. <IMAGE></p> |
