METHOD FOR MANAGING FILE IN LIBRARY AND SERVER DEVICE FOR LIBRARY

摘要

PROBLEM TO BE SOLVED: To provide a library server device which can deliver data containing moving picture data at requests from terminals for a network system which uses a library handling a recording medium, such as an optical disk, that is hardly accessed by more than one user because of its speed. SOLUTION: A reproduction request management part 192 of the server device 19 records a request to reproduce a file from a terminal device and finds a reproduction request frequency, a file management part 193 generates a copy of the file on another disk or hard disk 20 according to the reproduction request frequency, and a readout control part 194 reads data out of the original file or its copy and delivers the data.
