OPTICAL DISK RECORDING METHOD, OPTICAL DISK DEVICE, PROGRAM, AND RECORDING MEDIUM

摘要

In an optical disk recording method adapted to record information on an optical disk by a light beam incident to the disk in one direction, the disk has a plurality of rewritable recording layers including a first layer (L0) nearest to a plane of incidence and a second layer (L1) distant from the plane of incidence. A target layer where user data is to be recorded is specified from the first and second layers. Prior to recording the user data to a requested address in the second layer when the target layer is the second layer, a partial region (B) of the first layer corresponding to a same radial position as the requested address in the second layer is set to either a non-recorded state or a recorded state depending on a characteristic of the disk. The user data is recorded to the requested address in the target layer.
