ABSTRACT:
An optical disk device for recording data in an optical disk under ZCLV control is provided. The optical disk device divides the optical disk into a plurality of zones, and drives said optical disk at a linear velocity fixed in each zone but varied among the zones. At least one of the linear velocity and the number of zones of the optical disk is controlled in accordance with the amount of data to be recorded. Data recording time is reduced by dynamically changing at least one of the linear velocity and the number of zones of the optical disk in accordance with the amount of data to be recorded, rather than fixing the number of zones and the linear velocity thereof.
