Abstract
Technology is disclosed for improving read accuracy and storage capacity in optical data storage systems. The technology includes writing, with an optical write system, voxels into a voxel lattice having a voxel lattice constant (VLC) of an optical storage medium and reading, with an optical read system, the voxels from the optical storage medium. The optical read system includes optical components that have a point spread function (PSF). The VLC matches a shadow of the PSF either by virtue of the write system setting the VLC to match the shadow of the PSF of the read system or the read system adjusting the optical components to match the shadow of the PSF with the VLC. The system may be tuned by selecting which shadow of the PSF is used for matching with the VLC, the shape of the voxel lattice, the number of bits per voxel, or a combination.
