Multiple layer optical disc, and device for writing such disc

A medium access device includes a writer configured to write information in a logical storage space of a storage medium which has a physical storage space comprising two or more layers of physical storage locations. Each physical storage location has a physical address. The logical storage space includes storage locations within a first layer of the layers and within a subsequent layer of the layers. The storage locations in the logical storage space have contiguously numbered logical addresses. The access device further includes an address limit memory containing at least a value for a parameter indicating maximum value of the logical addresses of the storage locations in the first layer; and a processor configured to change the maximum value in the address limit memory and to provide an output when the maximum value cannot be changed to avoid attempting changing the maximum value.
