An optical disc drive according to the present invention writes information on an optical disc, which includes a substrate on which a number of pre-pits have been formed on its tracks and a recording film that is supported on the substrate. The optical disc drive includes a writing control section for instructing an optical pickup to record marks on the tracks by irradiating the recording film with a writing light beam. In accordance with information that defines, on the tracks, recordable areas Aa1 through Aa4 where the marks are recordable and pre-pit reading areas Ab1 through Ab4 where no marks are recordable, the writing control section controls the optical pickup so that the marks are recorded on at least some of the recordable areas. On the tracks on which the marks are recorded, each recordable area is shorter than any of the pre-pit reading areas.
