ABSTRACT:
An additional information signal is recorded at a predetermined position in a series of sectors in which image data coded by an intra-frame or intra-field coding method are recorded. The additional information signal is extracted and a pickup driving circuit is controlled. Thus, only the intra-frame or intra-field coded image data sets can be reproduced. A transfer rate is recorded as the additional information, so that the image data can be stably reproduced. It is possible to predict the position of the first sector to be the next reproduced of the series of sectors in which the intra-frame coded image data are recorded, on the basis of the position of the first one of the series of sectors in which intra-frame coded image data are recorded and the position of the first one of a previous series of sectors in which the intra-frame coded image data are recorded.
