Abstract

PURPOSE:To facilitate recording and reproducing by either constant angle speed driving or a constant line speed driving by providing a track equipped with first and second pre-format parts for driving a constant angle and for driving a constant line speed, respectively at one optical disk, and accessing either of them. CONSTITUTION:A disc-shaped optical disk 1 is divided into plural sets of concentric tracks of a first information track 101 and a second information track 102 from an outer circumference to an inner circumference, a first pre-format part 110 to record the constant angle speed driving information and a first information recording part 111 corresponding to this are provided at the first track 101 and a sector 112 constituted of these is provided over the whole circumference. Plural sectors are provided adjoining to the second information track 102 located at the inside of the track 101, and a second pre-format part 120 to record the constant line speed driving information to here and a second recording information part 121 corresponding to this are provided. Thus, the disk 1 is constituted, the pre-format part is put to proper use in accordance with the request of the constant angle driving or the constant line driving.
