In writing of optical data in an optical memory, the optical memory is linearly transported along a path past two or more physically separated write units. The two write units are provided at a distance from one another along the path and are mutually stepwise displaced in the path's transverse direction. The distance along the path separating write units is greater than a width of a preceding write unit. Each write unit is assigned to a section of the optical memory, with the result that the writing data is performed in the transport direction in separate and successive stages. Each stage contributes a fraction of the volume of information to be recorded during the writing.
