Data processing method, data processing device, information recording medium, and computer program

A data processing method for determining record data allocation on an information recording medium, said method comprising:

• a data size determining step of determining, in a decoding unit, a data size as a minimum size of data to be stored in the information recording medium on the basis of allowable jump range information determined as an allowable range of at least an inter-layer jump processing in a playback processing of said information recording medium, the allowable range of the inter-layer jump being no more than 40,000 sectors, and the allowable range of the intra-layer jump being 1/10-stroke, a full stroke being equivalent to a range from an innermost side to an outermost side of the recording medium, and the 40,000 sectors being less than the 1/10-stroke;
• and
• a data allocation determining step of determining, in the decoding unit, a data recording configuration in which a data block having said data size is so allocated as to be playable in the jump processing within said allowable jump range.

A data processing apparatus for determining record data allocation on an information recording medium, said apparatus comprising:

• a data size determining apparatus that determines a data size as a minimum size of data to be stored in the information recording medium on the basis of allowable jump range information determined as an allowable range of at least an inter-layer jump processing in a playback processing of said information recording medium, the allowable range of the inter-layer jump being no more than 40,000 sectors, and the allowable range of the intra-layer jump being 1/10-stroke, a full stroke being equivalent to a range from an innermost side to an outermost side of the recording medium, and the 40,000 sectors being less than the 1/10-stroke;
• and
• a data allocation determining apparatus that determines a data recording structure in which a data block having said data size is so allocated as to be playable in the jump processing within said allowable jump range.

A non-transitory computer readable medium including computer executable instructions for executing a record data allocation determining processing on an information recording medium, said computer executable instructions causing a computer to execute:

• a data size determining step of determining a data size as a minimum size of data to be stored in the information recording medium on the basis of allowable jump range information determined as an allowable range of at least an inter-layer jump processing in a playback processing of said information recording medium, the allowable range of the inter-layer jump being no more than 40,000 sectors, and the allowable range of the intra-layer jump being 1/10-stroke, a full stroke being equivalent to a range from an innermost side to an outermost side of the recording medium, and the 40,000 sectors being less than the 1/10-stroke;
• and
• a data allocation determining step of determining a data recording structure in which a data block having said data size is so allocated as to be playable in the jump processing within said allowable jump range.
