Abstract
The shaping of pixels of a data page for holographic recording, a holographic recording medium including data pages with shaped pixels, and apparatuses for writing to or reading from such holographic recording media are disclosed.A device for modulating a light beam to generate a data page having a plurality of pixels applies a spatially varying pixel size over the data page. An apparatus for writing to holographic recording media includes such a device for modulating a light beam, while an apparatus for reading from holographic recording media includes an adapted detector for detecting the data page having a plurality of pixels with a spatially varying pixel size.
