Apparatus, method, and program product for secure data formatting and retriving, and computer readable transportable data recording medium storing the program product

A computer program product stored on a computer readable transportable storage medium for, when run on a data processing apparatus, carrying out a data recording operation to the computer readable transportable storage medium, comprising steps of:

• providing a recordable area which allows recording of data thereinto and reading of the data therefrom and a read only area which stores a plurality of programs comprising:
• a copy judging program judging whether a computer readable transportable information recording medium has undergone a copy operation;
• a first password control program;
• a recording program recording data;
• a decoding program decoding the data encrypted and stored in the recordable area;
• and
• a second password control program judging a password when the decoding program is activated;
• activating the copy judging program when the computer readable transportable information recording medium is placed in a computer;
• identifying control data, track description unit, and run out block indicators using the copy judging program;
• comparing control data to track description unit using the copy judging program to assign a first value to a first variable;
• determining whether the run out block indicators are irregular to assign a second value to a second variable;
• judging with the copy judging program whether the computer readable transportable information recording medium has undergone a copy operation based on the first and second variables;
• if the computer readable transportable information recording medium has undergone a copy operation, determining whether the copy operation was authorized or unauthorized;
• initiating the second password control program when the copy judging program judges that the computer readable transportable information recording medium has not undergone an unauthorized copy operation and when a way of data storing is set;
• checking if a password is correct with the second password control program;
• opening the decoding program upon a time the password is checked as correct with the second password control program;
• decoding data encrypted and stored in the recordable area of the computer readable transportable information recording medium, using the decoding program;
• starting the recording program;
• and
• recording the data decoded in the decoding step into a different information recording medium connected to a computer.
