摘要： A code conversion apparatus, a disk drive, a code buffer, and an encryption buffer are included in a storage. The code buffer stores therein first encrypted data present in the disk drive, and the encryption buffer stores therein first unencrypted data present in the disk drive. An encrypting unit encrypts the first unencrypted data present in the encryption buffer to predetermined encrypted data, and a decrypting unit decrypts the first encrypted data present in the code buffer to second unencrypted data. Moreover, a re-encrypting unit decrypts the first encrypted data present in the code buffer to third unencrypted data and encrypts the third unencrypted data to second encrypted data different from the first encrypted data.
