Abstract
A movement device of a recording determination apparatus moves a pickup in a radial direction of an optical disc. The pickup irradiates laser light to the optical disc to output an electric signal, based on reflected light from a laser spot. A control device acquires address information relating to an arrangement position of the laser spot, based on the electric signal. The control device controls the movement device to move the laser spot from a data area to a recordable area. The control device determines whether or not data is recorded in the recordable area, based on the electric signal until a reference time has elapsed from a border potion between the data area and the recordable area, the border portion being specified based on the address information.
Claims6
A recording determination apparatus that determines whether or not data is recorded in a recordable area in an optical disc including an annular data area and the annular recordable area arranged inside or outside the data area, in which data can be recorded, the recording determination apparatus comprising:
- a motor that rotates the optical disc;
- a pickup that irradiates laser light to the optical disc to form a laser spot on the optical disc, and to output a signal based on reflected light from an arrangement position of the laser spot;
- a movement device that moves the pickup in a radial direction of the optical disc;
- and
- a control device,
- wherein the control device comprises:
- an acquirement unit that acquires address information relating to the arrangement position of the laser spot, based on the signal from the pickup;
- a movement control unit that controls the movement device to move the laser spot from the data area to the recordable area;
- and
- a determination unit that determines whether or not the data is recorded in the recordable area, based on the signal, until a reference time has elapsed from a border portion between the data area and the recordable area, the border portion being specified based on the address information.
A recording determination program stored on a computer-readable medium that determines whether or not data is recorded in a recordable area in an optical disc including an annular data area and the annular recordable area arranged inside or outside the data area, in which the data can be recorded, the recording determination program causing a computer to execute the steps of:
- moving a pickup from the data area to the recordable area;
- acquiring address information relating to an arrangement position of a laser spot formed on the optical disc by the pickup, based on a signal generated in accordance with reflected light of the laser spot;
- and
- determining whether or not the data is recorded in the recordable area, based on the signal until a reference time has elapsed from a border portion between the data area and the recordable area, the border portion being specified based on the address information.
A recording determination method that determines whether or not data is recorded in a recordable area in an optical disc including an annular data area and the annular recordable area arranged inside or outside the data area, in which the data can be recorded, the recording determination method including the steps of:
- moving a pickup from the data area to the recordable area;
- acquiring address information relating to an arrangement position of a laser spot formed on the optical disc by the pickup, based on a signal generated in accordance with reflected light of the laser spot;
- and
- determining whether or not the data is recorded in the recordable area, based on the signal until a reference time has elapsed from a border portion between the data area and the recordable area, the border portion being specified based on the address information.
