PROBLEM TO BE SOLVED: To solve the problem that data for special reproduction sometimes exceed the data size of an area TPA which is allocated as a recording area for data for special reproduction when the data for special reproduction is recorded on magnetic tape. SOLUTION: An image data converting circuit 21 selects parts of an image to be displayed as a special reproduction image from input image data, and fills the rest of the image with image data which does not generate code amount. Specifically, it fills the rest of the image with monochromatic image data such as white and black. An image TP data creating circuit 22 encodes the converted image data as an I picture. A code amount judging circuit 23 judges whether the code amount of the encoded image data does not exceed a specified code amount. If it exceeds the specified code amount, the image data converting circuit 21 is controlled so as to perform conversion of the image data so that the number of pixels filling the black part is increased by a certain number with respect to that of the last time, according to the judgment signals from the code amount judging circuit 23.
