摘要： To increase the cache hit ratio of a requested image and shorten the user's average waiting time, images of a CD-ROM changer are cached in an intermediate HDD having a high retrieval speed, and provided to the user. When a requested image is not cached in the intermediate HDD, the free volume of the intermediate HDD is checked. If the intermediate HDD is judged not to have a free volume, images of hierarchies having large volumes are erased from ones stored the intermediate HDD in the order from lower popuralities or older access dates.
