Abstract:
A method for recording data in an optical memory having at least one light-sensitive layer, the method comprising:providing at least two write units (S.sub.1, S.sub.2 . . . ) at a distance from one another along a travel path and mutually stepwise displaced in a direction transverse to the travel path, each write unit (S) being assigned to a section of the optical memory;transporting the optical memory past the at least two write units in linear movement along the travel path;providing the optical memory with at least two physically separated fields (F) of substantially equal length for writing at each stage, each field (F.sub.1, F.sub.2 . . . ) substantially corresponding to the section of the optical memory assigned to a respective write unit (S.sub.1, S.sub.2 . . . ); andwriting the data in the direction of the transport path in separate and successive stages respectively, the writing including writing, at each stage, a fraction of the data which are to be recorded, the fraction substantially being proportional to an inverse of a number of write units (S.sub.1, S.sub.2 . . . );said write units being each spaced, in the direction of the travel path, from adjacent write units, by a distance substantially equal to the spacing of plural optical memories along said travel path.
