Abstract
A selection device for a reading and/or writing device for a rewritable Digital Versatile Disk (DVD) includes a selector for selecting a specified complete and limited data area of a plurality of such data areas present on the DVD after a Lead-in Area, and a representer for representing the selected data area to the operating system of a data processing unit, which can only access to a first or a single data area on the DVD as this single or only data area. By transferring a start address of the first or only single data area, which the operating system can access, into a start address of the selected data area, an inquiry of the operating system to the first or single data area is diverted to the selected data area.
