- the dummy data is recorded in the area 281 which is the unrecorded area of the LO layer area RO-0, and the LO layer area RO-0 is formatted. Since data is already recorded in the LO layer area 282, dummy data is not recorded in the area 282.
- step S52 If it is determined in step S52 that the format of the region Rx-l of the L1 layer is completed, that is, the format of the region LOx-1 of the L1 layer is completed. If the formatting of the area Rx-0 is completed and it is determined that the area is a bad one, the process proceeds to step S54, and the de-ice processing section 401 of the format processing section 335 controls the signal processing section 56 to control the area Rx of the L0 layer. Format —O and the process ends.
- step S51 determines whether the formatting of the LO layer region Rx-O is complete. If it is determined that the format of the area Rx—1 is not completed, the process proceeds to step S55, and the de-ice processing section 401 of the format processing section 335 controls the signal processing section 56 to change the area Rx-1 of the L1 layer. Formatting is completed.
- the format processing unit 335 In the process of formatting the area Rx, when the recording layer area Rx to be formatted is the last area, that is, when the formatting of the recording layer area Rx is completed, the formatting of the optical disc 33 is completed. In this case, after the dice processing unit 401 of the format processing unit 335 controls the signal processing unit 56 to format the area Rx of the recording layer, the format processing unit 335 has a user area adjacent to the user area. The necessary information is recorded in the outer area of the optical disc than the lead-out area or middle Create an area.
- the format processing unit 335 further controls the signal processing unit 56 to record the necessary data in the outermost area on the LO layer and the outermost area on the L1 layer, and in the lead-out area.
- the optical disk 33 is in a fully formatted state.
- the recording / reproducing device 31 formats the region Rx with reference to the final recording address recorded by the final recording address storage unit 334 as necessary.
