Information recording medium, information recording device and method, and computer program

An information recording apparatus for recording information to be recorded onto an information recording medium comprising:

• a user information recording area in which user information can be recorded, said user information recording area having pre-recorded areas in which recording/reproduction of the user information is prevented, said user information recording area being divided by the pre-recorded areas into a plurality of partial recording areas including a partial recording area, smaller than a unit area, in which record information of a read-only recording medium is recorded, the unit area having a size of an area on the information recording medium in which a size of data for recording or reproducing is recorded,
• wherein operation-forbidding information invalidates an operation instruction by a user that is intended for the user information recorded in the partial recording areas in a reproduction period when data are recorded in the pre-recorded areas and before the reproduction period, the operation-forbidding information being written in at least one of the pre-recorded areas and an area which is outside said user information recording area,
• said information recording apparatus comprising:
• a writing device capable of writing the user information into said user information recording area;
• and
• a controlling device for controlling said writing device to write the user information into an area other than the pre-recorded areas out of said user information recording area.

An information recording method of recording information to be recorded onto an information recording medium comprising:

• a user information recording area in which user information can be recorded, said user information recording area having pre-recorded areas in which recording/reproduction of the user information is prevented, said user information recording area being divided by the pre-recorded areas into a plurality of partial recording areas including a partial recording area, smaller than a unit area, in which record information of a read-only recording medium is recorded, the unit area having a size of an area on the information recording medium in which a size of data for recording or reproducing is recorded,
• wherein operation-forbidding information invalidates an operation instruction by a user that is intended for the user information recorded in the partial recording areas in a reproduction period when data are recorded in the pre-recorded areas and before the reproduction period, the operation-forbidding information being written in at least one of the pre-recorded areas and an area which is outside said user information recording area,
• said information recording method comprising:
• a writing process of writing the user information into an area other than the pre-recorded area out of said user information recording area.

A non-transitory computer program product in a computer-readable medium embodying a program of instructions executable by a computer provided in an information recording apparatus, the computer program product making the computer function as at least one portion of a controlling device and a writing device,

• said information recording apparatus for recording information to be recorded onto an information recording medium comprising:
• a user information recording area in which user information can be recorded, said user information recording area having pre-recorded areas in which recording/reproduction of the user information is prevented, said user information recording area being divided by the pre-recorded areas into a plurality of partial recording areas including a partial recording area, smaller than a unit area, in which record information of a read-only recording medium is recorded, the unit area having a size of an area on the information recording medium in which a size of data for recording or reproducing is recorded,
• wherein operation-forbidding information invalidates an operation instruction by a user that is intended for the user information recorded in the partial recording areas in a reproduction period when data are recorded in the pre-recorded areas and before the reproduction period, the operation-forbidding information being written in at least one of the pre-recorded areas and an area which is outside said user information recording area,
• said information recording apparatus comprising:
• said writing device capable of writing the user information into said user information recording area;
• and
• said controlling device for controlling said writing device to write the user information into an area other than the pre-recorded areas out of said user information recording area.
