Abstract
A continuous addressing optical disk including a plurality of recording layers is provided. Wherein, the Nth recording layer has a plurality of data sectors with continuous addresses. The (N+1)th recording layer has a plurality of data sectors with continuous addresses. Wherein, the addresses of the data sectors of the Nth and (N+1)th recording layers are continuous. The present invention will not waste the addressing space for multi-layer optical disk because the addresses of data sectors of adjoining recording layers are continuous.
Claims12
A continuous addressing multi-layer optical disk, comprising:
- a plurality of recording layers, each recording layer respectively having a plurality of sectors, wherein the sectors are divided into at least a user region and at least a control region, wherein each sector has a PSN address and a region type, the PSN addresses of the sectors in an Nth recording layer are continuous, the PSN addresses of the sectors in an (N+1)th recording layer are continuous, and the PSN addresses of the user region in the Nth and (N+1)th recording layers are continuous.
A continuous addressing method, comprising:
- providing a multi-layer optical disk including a plurality of recording layers, each recording layer respectively having a plurality of sectors, wherein each sector has a PSN address and a region type;
- dividing the sectors into at least a user region and at least a control region by defining the region type;
- defining the PSN addresses of the sectors of an Nth recording layer in the recording layers such that the PSN addresses of the sectors of the Nth recording layer are continuous;
- and
- defining the PSN addresses of the sectors of an (N+1)th recording layer in the recording layers such that the PSN addresses of the sectors of the (N+1)th recording layer are continuous;
- wherein the PSN addresses of the user region of the Nth and (N+1)th recording layers are continuous.
