PROBLEM TO BE SOLVED: To provide a buffer list control method capable of improving a hit rate and accelerating the average speed of access to stored data. SOLUTION: Concerning the buffer managing method for accessing data inside a secondary storage device after storing them in a buffer, the number of times of access after storing respective data in the buffer is stored for each piece of data, plural pointers are prepared for inserting buffer information in the middle of a buffer list having the list of respective pieces of buffer information showing respective buffers, and when data are read out in the buffer at the time of requesting the acquisition of the data, the number of times of access corresponding to the relevant data is acquired. When that number of times of access is more than the prescribed number of times, the buffer information showing the said buffer is moved from a position on the buffer list corresponding to the kind of the relevant data to a position closer to the end, but when it is less than the prescribed number of times, this buffer information is moved to a position corresponding to the kind of the data.
