Patent ID: 7359623

Claim:
A file reproducing apparatus for reproducing files recorded on a recording medium using a FAT file system, the files to be reproduced including motion picture data, said file reproducing apparatus comprising: a reading section that reads the motion picture data of a file from the recording medium; a reproduction processor that applies a predetermined reproduction process to the motion picture data read by said reading section; a data storage device; and a controller configured to: control said reading section, said reproduction processor, and said data storage device; and generate a cluster table on said data storage device when the motion picture data is reproduced in a forward direction or when a cluster is retrieved for reading a header of a file including motion picture data, wherein: the cluster table associates an offset position, indicating a position relative to a head of a file and being set at a predetermined offset interval, with a cluster number indicating a location on the recording medium on which the motion picture data at the corresponding offset position is stored; said data storage device stores the cluster table; and said controller determines a location on the recording medium at which the motion picture data to be read by said reading section is located with reference to the cluster table during a reproducing operation in a reverse direction which proceeds from an end of the file toward the head thereof.
