Abstract

Disclosed is a recording apparatus for editing data and recording a file which is an editing result. The apparatus is configured by a file generating section for generating a file and a recording section for recording the file which is generated by the file generating section, in a recording medium. The file is composed of a management information block and a data block. The management information block has at least an image management track for storing management information necessary for reproducing image data with respect to each predetermined unit reproducing time, an identifier of the image management track, and a display control track for storing management information of display control data which is composed of a display position of an image which corresponds to the image data. The data block is capable of storing data which is managed by the management information block.
