A data outputting method, including the steps of converting input data into sector unit data that starts with a start code and a header preceded by the start code, the header being composed of two bits, at least one of which represents an encryption control; when the converted data is to be encrypted, setting at least one of the two bits preceded by the start code to a state that represents that the data has been encrypted; encrypting the converted data; encoding the encrypted data; and outputting the encoded data.
