Abstract
In an information recording device and method, user data are recorded in a recording medium having two or more recording layers and having a data area in which user data is recordable for each recording layer. A closing command is received after recording of user data in the data area of the recording medium is performed in response to a user-data write request. A minimum amount of lead-out data are written to the recording medium following an end position of the recorded user data in the data area of the recording medium, based on the received closing command.
Claims18
An information recording device which records user data in a recording medium having two or more recording layers and having a data area in which user data is recordable for each recording layer, comprising:
- a receiving unit receiving a closing command after recording of user data in the data areas of the recording medium is performed in response to a user-data write request;
- and
- a writing unit writing a minimum amount of lead-out data to the recording medium following an end position of the recorded user data in the data areas of the recording medium, based on the received closing command, wherein the writing unit is provided to write the minimum amount of lead-out data to the recording medium when the received closing command contains a close function indicating a command of minimum-amount lead-out data write request.
An information recording method which records user data in a recording medium having two or more recording layers and having a data area in which user data is recordable for each recording layer, comprising the steps of:
- receiving a closing command after recording of user data in the data areas of the recording medium is performed in response to a user-data write request;
- and
- writing a minimum amount of lead-out data to the recording medium following an end position of the recorded user data in the data areas of the recording medium, based on the received closing command, wherein the step of writing is provided to write the minimum amount of lead-out data to the recording medium when the received closing command contains a close function indicating a command of minimum-amount lead-out data write request.
A computer-readable medium having a program embodied therein for causing a computer of an information recording device to execute an information recording method which records user data in a recording medium having two or more recording layers and having a data area in which user data is recordable for each recording layer, the method comprising the steps of:
- receiving a closing command after recording of user data in the data areas of the recording medium is performed in response to a user-data write request;
- and
- writing a minimum amount of lead-out data to the recording medium following an end position of the recorded user data in the data areas of the recording medium, based on the received closing command, wherein the step of writing is provided to write the minimum amount of lead-out data to the recording medium when the received closing command contains a close function indicating a command of minimum-amount lead-out data write request.
An information recording method which records user data in a rewritable recording medium having a plurality of recording layers, the information recording method comprising the steps of:
- recording user data in data areas spanning the plurality of recording layers of the recording medium;
- determining, when writing lead-out data extending from an end of the data areas where the user data is recorded to an end of a lead-out area in the recording medium, whether a non-recorded region exists in an area following the end of the lead-out area;
- writing, when the non-recorded region does not exist, only said lead-out data to the recording medium;
- and
- writing, when the non-recorded region exists, said lead-out data, and additional lead-out data covering the non-recorded region, to the recording medium.
An information recording device which records user data in a rewritable recording medium having a plurality of recording layers, the information recording device comprising:
- a recording unit for recording user data in data areas spanning the plurality of recording layers of the recording medium;
- and
- a determination unit for determining, when writing lead-out data extending from an end of the data areas where the user data is recorded to an end of a lead-out area in the recording medium, whether a non-recorded region exists in an area following the end of the lead-out area,
- wherein the recording unit is configured to write, when the non-recorded region does not exist, only said lead-out data to the recording medium, and to write, when the non-recorded region exists, said lead-out data, and additional lead-out data covering the non-recorded region, to the recording medium.
A computer-readable medium having a program embodied therein for causing a computer of an information recording device to execute an information recording method which records user data in a rewritable recording medium having a plurality of recording layers, the information recording method comprising the steps of:
- recording user data in data areas spanning the plurality of recording layers of the recording medium;
- determining, when writing lead-out data extending from an end of the data areas where the user data is recorded to an end of a lead-out area in the recording medium, whether a non-recorded region exists in an area following the end of the lead-out area;
- writing, when the non-recorded region does not exist, only said lead-out data to the recording medium;
- and
- writing, when the non-recorded region exists, said lead-out data, and additional lead-out data covering the non-recorded region, to the recording medium.
