摘要：
An optical disc reproduction apparatus includes a sector detection section for detecting a sector; a sector reproduction time measuring section for measuring a reproduction time of the sector, and outputting sector reproduction time data which represents the measured reproduction time of the sector; an unrecorded portion detection section for detecting an unrecorded portion which is a portion of the sector in which no data is recorded; an unrecorded portion time measuring section for measuring a reproduction time of the unrecorded portion, and outputting unrecorded portion time data which represents the measured reproduction time of the unrecorded portion; and a sector determination section for determining whether the sector is an unrecorded sector or not, based on a relationship between the sector reproduction time data and the unrecorded portion time data, the unrecorded sector being a sector which is in an unrecorded state.
