Abstract
A recording apparatus includes: a recording unit configured to perform recording of information on a recoding medium having a plurality of layers serving as recording layers where recording of information is performed, and a track serving as a continuous recording area is formed in the plurality of layers and recording of data is performed within a track; and a control unit configured to cause the recording unit to execute recording to the recording medium according to a request from a host apparatus, and also to enable the host apparatus to recognize, in the event of determining that a certain layer of the recording medium is in a recording disabled state, that all of tracks in this layer are in a recording disabled state.
Claims17
A recording apparatus comprising:
- a recording unit configured to perform recording of information on a recording medium having a plurality of layers serving as recording layers where recording of information is performed, and a track serving as a continuous recording area is formed in the plurality of layers and recording of data is performed within a track;
- and
- a control unit configured to cause the recording unit to execute recording to the recording medium according to a request from a host apparatus, and also to enable the host apparatus to recognize, in the event of determining that a certain layer of the recording medium is in a recording disabled state, that all of tracks in this layer are in a recording disabled state,
- wherein the control unit sets unrecorded area size information of all of tracks in a layer determined to be in the recording disabled state to zero, thereby enabling the host apparatus to recognize that all of the tracks in this layer are in the recording disabled state.
A recording method comprising:
- recording information on a recording medium comprising a plurality of layers serving as recording layers to record information, and a plurality of tracks serving as continuous recording area formed in each of the plurality of layers, wherein the information is recorded within the plurality of tracks in response to a request from a host apparatus;
- and
- recognizing, in the event of determining that one or more layers of the plurality of layers are in a recording disabled state, that each of the plurality of tracks in the determined one or more layers are in the recording disabled state,
- wherein when unrecorded area size information of each of the plurality of tracks in the one or more layers is set to zero, each of the plurality of tracks in the one or more layers is recognized to be in the recording disable state.
A non-transitory computer readable storage medium having stored thereon, a computer program having at least one code section executable by a computer, thereby causing the computer to perform the steps comprising:
- recording information on a recording medium, wherein the recording medium comprises a plurality of layers to record the information, wherein each of the plurality of layers comprises a plurality of tracks serving as continuous recording area, and wherein the information is recorded within the plurality of tracks in response to a request from the computer;
- determining one or more layers of the plurality of layers that are in a recording disable state;
- and
- recognizing whether each of the plurality of tracks associated with each of the determined one or more layers are in the recording disable state,
- wherein when unrecorded area size information of each of the plurality of tracks in the one or more layers is set to zero, each of the plurality of tracks in the one or more layers is recognized to be in the recording disable state.
