The invention relates to the shaping of pixels of a data page for holographic recording, to a holographic recording medium including data pages with shaped pixels, and to apparatuses (1) for writing to or reading from such holographic recording media. According to the invention, a device for modulating a light beam (2) to generate a data page having a plurality of pixels applies a spatially varying pixel size over the data page. An apparatus (1) for writing to holographic recording media includes such a device for modulating a light beam (2), while an apparatus (1) for reading from holographic recording media includes an adapted detector means (9) for detecting the data page having a plurality of pixels with a spatially varying pixel size.
