A method of operating a medium access device includes writing by a writer 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 storage location having a physical address, the logical storage space comprising 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 having contiguously numbered logical addresses; storing in an address limit memory at least a value for a parameter indicating a maximum value of the logical addresses of the storage locations in the first layer; and changing by a processor 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. |
