Abstract
There is provided a recording apparatus including a light radiating unit that radiates light to an optical recording medium, a recording unit that performs light emission control of the light radiating unit, and performs recording on the optical recording medium, and a control unit that performs control in a manner that, in a state in which a logical address space, a virtual address space obtained by adding at least a spare area to the logical address space, and a physical address space obtained by adding a buffer area to the virtual address space are defined, a process for replacing a recording area of the optical recording medium with the spare area is executed using a virtual address.
Claims18
A recording apparatus comprising:
- a light radiating unit that radiates light to an optical recording medium;
- a recording unit that performs light emission control of the light radiating unit, and performs recording on the optical recording medium;
- and
- a control unit that performs execution of a process for replacing a recording area of the optical recording medium with a spare area using a virtual address that corresponds to the spare area, wherein the process is executed in a state in which a logical address space, a virtual address space, and a physical address space are defined, wherein the virtual address space is obtained by adding at least the spare area to the logical address space, and wherein the physical address space is obtained by adding a buffer area to the virtual address space,
- wherein the control unit registers in a defect list, based on the virtual address space, information of virtual addresses of a replacement source and a replacement area that corresponds to the spare area, after the replacement area is secured.

A recording method comprising:
- executing a process for replacing a recording area of an optical recording medium with a spare area using a virtual address that corresponds to the spare area, wherein the process is executed in a state in which a logical address space, a virtual address space and a physical address space are defined, wherein the virtual address space is obtained by adding at least the spare area to the logical address space, and wherein the physical address space is obtained by adding a buffer area to the virtual address space,
- wherein information of virtual addresses of a replacement source and a replacement area that corresponds to the spare area is registered in a defect list based on the virtual address space, after the replacement area is secured.
A reproducing apparatus comprising:
- a light radiating unit that radiates light to an optical recording medium, wherein a process for replacing a recording area of the optical recording medium with a spare area is executed using a virtual address that corresponds to the spare area, in a state in which a logical address space, a virtual address space and a physical address space are defined, wherein the virtual address space is obtained by adding at least the spare area to the logical address space, and wherein the physical address space is obtained by adding a buffer area to the virtual address space;
- a reproducing unit that reproduces recording information of the optical recording medium based on a light reception signal received in response to the light radiated to the optical recording medium by the light radiating unit;
- and
- a control unit that causes the reproducing unit to execute a reproducing operation based on first relationship information indicating a relationship between a logical address and the virtual address, according to a reproducing instruction based on the logical address,
- wherein the control unit registers in a defect list, based on the virtual address space, information of virtual addresses of a replacement source and a replacement area that corresponds to the spare area, after the replacement area is secured.
2 more elements
A reproducing method, comprising:
- performing a reproducing operation on an optical recording medium, wherein a process for replacing a recording area of the optical recording medium with a spare area is executed using a virtual address that corresponds to the spare area, based on first relationship information indicating a relationship between a logical address and the virtual address according to a reproducing instruction based on the logical address,
- wherein the process is executed in a state in which a logical address space, a virtual address space, and a physical address space are defined, wherein the virtual address space is obtained by adding at least the spare area to the logical address space, and wherein the physical address space is obtained by adding a buffer area to the virtual address space,
- wherein information of virtual addresses of a replacement source and a replacement area that corresponds to the spare area is registered in a defect list based on the virtual address space, after the replacement area is secured.
