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. |
