PROBLEM TO BE SOLVED: To provide a file system capable of realizing high-speed real-time writing, and utilizing effectively a band width, concerning the file system receiving a file writing request of an optional size. SOLUTION: When receiving the file writing request from a server application 21, a block determination part 221 transfers requested data to a delay writing buffer 223. Then, the block determination part 221 determines whether readout from a data memory part 24 is required or not based on continuity of a writing start position and the position of a block which is a unit for writing in the data memory part 24. A delay readout processing part 225 executes readout processing only when determined as required by the block determination part 221. After the data is transferred from the block determination part 221 and read out by the delay readout processing part 225, a delay writing processing part 224 writes the block having arranged data in the data memory part 24 at every fixed period.
