ABSTRACT:
An optical disc apparatus comprises: a data reading unit for reading VTS_TMAPT and TMU; a preliminary search address calculating unit for calculating, based on the read data and a search time designated by a user, address of a destination VOBU to which an optical pickup is to be moved; a VOBU reading unit for reading a cell time, a VOBU time and video data reproduction time of the destination VOBU; a VOBU determining means for determining whether the designated search time belongs to reproduction time zone of the destination VOBU; and a search address calculating unit for calculating, based on VOBU_SRI data of the destination VOBU, address of a next destination VOBU when the designated search time is determined to be outside the reproduction time zone of the destination VOBU. This disc apparatus can accurately find a point of the designated search time from which to start reproducing video data.
