摘要：
An optical disk having thereon intermittent spiral guiding grooves composed of a pit array, wherein each guiding groove has a wobbling side wall at either side, so that the pit array is used as a data reproduce-only area and spaces between adjacent guiding grooves are used as a data recordable area, thereby realizing a high-density optical disk having both the data reproduce-only area and data recordable area.
