- step S101 when the received close command includes the Close Function "111" indicating the minimum read data recording request command, the user data recording end address position (X position in FIG. 3B, FIG. 4B It is determined whether there is a difference between the (X position) ′) and the start address of the readout area by address comparison (step S102).
- step S102 If it is determined in step S102 that there is a difference, the minimum readout data composed of 64 ECC blocks is recorded after the recording end address of the user data in the data area (step S103). After the end of step S103, the optical disk 2 is taken out.
- step S101 the close command from the host computer If it is determined that the Close Track / Session Command does not include the Close Function “111” indicating the minimum required reset data recording request command, the recording end address of the user data in the data area is changed to the number of the reset event area. The readout data is recorded in the entire area up to the end address (step S104). After the end of step S104, the optical disk 2 is taken out.
- the close command Close Track / Session Command from the host computer includes the Close Function “111” indicating the minimum read data data recording request command, and the recording end address of the user data in the data area and the read out. If it is determined that there is no difference from the start address of the area, the readout data is recorded in the entire area from the recording end address of the user data to the end address of the readout area in the data area (step S104). After the completion of step S104, the optical disk 2 is taken out.
- the lead-out data is recorded following the user data, so that a plurality of recording layers (layer 0, layer '1) are recorded. ) Can be kept compatible with a read-only information recording medium.
- Step S101 if the Close Command / Close Command from the host computer indicates the minimum read data data recording request command Close Function "111", the read data recorded is minimal. Is the data amount. As a result, it is not necessary to record read data over all of the unrecorded areas in the data area, so that the time required for taking out the optical disc 2 after recording user data can be reduced.
- FIG. 8 is a flowchart for explaining another process for implementing a method of recording lead-out data when recording of user data ends in the middle of Layer 1.
- FIGS. 9A and 9B illustrate a command (bend down command CDB: CB) and a data format for recording an unrecorded area in the data area output from the host computer to the optical disc apparatus 1 with lead-out data.
- the CPU 13 of the optical disk device 1 is a recording request command for recording an unrecorded area in the data area with read data from the host computer.
- step S202 if there is no unrecorded area in the data area, it is determined in step S202 that there is no unrecorded area in the data area. .
- the optical disk device 1 returns a command Complete in response to a command (vendor unique command CDB: CB) transmitted from the host computer for recording an unrecorded area as read fat data (step S205).
- a command vendor unique command CDB: CB
- step S202 when it is determined that the unrecorded ⁇ II area exists in the data area, the start address of the unrecorded area and the end address of the readout area are determined. , The recording time required to record the readout data in all the unrecorded areas is calculated, and the calculated recording time of the unrecorded area is transferred to the host computer (step S203).
- the recording time is set to "0" and the data is transmitted to the host computer. Is transferred (step S203). After the data is transferred to the host computer, the unrecorded area in the data area is recorded with the read data (step S204).
- the command (vendor unique command CDB: CB) for recording all the unrecorded area with the read data
- the user data Since the unrecorded area of the data area where the data is recorded is recorded as the lead-out data, for example, when the user reproduces the data of the first recording layer (layer 0)
- the second address is obtained by seeking to the target address.
- the read laser is focused on the recording layer (Layer 1)
- the data on the first recording layer (Layer 0) is recorded because no data is recorded on the second recording layer (Layer 1) at the same radial position. Can not be reproduced.
- step S301 the optical disc device 1 inserts the disc when there is no disc access command from the host computer.
- the inserted optical disc 2 which is a single-sided, two-layer DVD disc, it is checked by RF check whether or not there is a force in which an unrecorded area exists (step S302).
- step S302 if an unrecorded area exists in the data area as shown in FIG. 3D or 4D, it is determined in step S302 that an unrecorded area exists in the data area.
- the optical disk device 1 records read format data in an unrecorded area in the data area at the time of the pack format without outputting a disk access command from the host computer (step S303).
- step S302 if no unrecorded area exists in the data area as shown in FIG. 3C or FIG. 4C, it is determined in step S302 that no unrecorded area exists in the data area. You. In this case, the state shifts to a state of waiting for a command from the host computer.
- the read format data is recorded in the unrecorded area in the data area of the optical disc 2 at the time of the background format in which the disc access command is not output from the host computer. Therefore, for example, when the user reproduces the data of the first recording layer (layer 0) and seeks to the target address and happens to focus on the second recording layer (layer 1), the read laser is focused. However, it is possible to avoid the problem that the data on the first recording layer (layer 0) cannot be reproduced because no data is recorded on the second recording layer (layer 1) at the same radial position. Moreover, such lead-out data recording is performed during a background format in which a disk access command is not output from the host computer, so that it takes a longer time to remove the optical disk 2 after data recording. Does not occur.
