摘要：
A CPU (11) of a personal computer (1) instructs a CPU (32) of an adapter (26) comprising a semiconductor IC to calculate the hash value of a tune database for managing the contents recorded on an HDD (21) and to store the hash value in a nonvolatile memory (34). When the contents recorded on the HDD (21) are reproduced, the CPU (11) calculates the hash value of the tune database, compares it with the hash value stored in the nonvolatile memory (34), and control the reproduction of the contents from the HDD (21) according to the results of the comparison.
