Data page with increased data capacity

The present invention relates to a data page (6) for an optical storage system with an increased data capacity, to a modulation method and a method for recording such a data page (6), and to an apparatus for reading from and/or writing to optical storage media using such a modulation method or recording method. According to the invention, in a data page (6) for an optical storage system, wherein data are arranged as an array (1) of pixels (2), where each pixel (2) has a size below the optical resolution of the optical storage system, and wherein data bits are represented by groups of pixels (3), where each group of pixels (3) has a size equal to or greater than the optical resolution of the optical storage system, the positions (4) and/or the sizes of the groups of pixels (3) are adjustable in steps of the pixel size.
