Method of processing data and data processing apparatus

摘要

By the method of processing data, the data can be processed, without encrypting and decrypting all of the data, so as to keep secrecy of the data. The method comprises the steps of: storing data of a system area of a recording medium, which are used by the writing means so as to recognize the recording medium; encrypting at least a part of the data of the system area on the basis of a password; storing main data; writing the encrypted data of the system area in the recording medium; and writing the main data in the recording medium.
