Patent ID: 8300509

Claim:
A recording determination apparatus for determining presence data is recorded in an annular recordable area of an associated optical disc including an annular data area arranged adjacent to the annular recordable area, 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, the address information specifying a border portion between the data and recordable areas of the associated optical disc; a movement control unit that controls the movement device to move the laser spot from the data area through the border portion and into the recordable area; and a determination unit configured to commence, when the laser spot is moved to the border portion, determining a presence of the data recorded in the recordable area, based on the signal, until a reference time has elapsed from a time the laser spot is first moved to the border portion between the data area and the recordable area.
