ABSTRACT:
An optical disk101in which information is recorded on a groove track, and an optical disk107in which information is recorded on a land track. The optical disk101has a control data area102,and a data recording area103in which user data is recorded. The optical disk107has a control data area108,and a data recording area109in which user data is recorded. A code for indicating the groove track or the land track onto which a tracking servo control is to be executed is provided both in the control data area102of the optical disk101,and in the control data area108of the optical disk107.
