Abstract

Formatting a volumetric three-dimensional optical carrier across hundreds of recording layers requires positional accuracy that no single formatting session can maintain globally, for reasons rooted in the physics of focused beam propagation. Finite objective working distance, depth-dependent spherical aberration, and layer-to-layer reference error accumulation each impose independent ceilings on lattice coherence, and their combined effect places the achievable coherence depth well below the layer counts implied by recent petabit-scale density demonstrations. This paper examines sub-volume independence as a structural design principle that responds to these constraints by partitioning the carrier volume into bounded domains, each formatted to a locally coherent lattice and separated by boundary markers that encode domain transitions in place of a globally maintained coordinate system. The analysis develops the physical basis for the coherence ceiling, traces the consequences of domain partitioning for interlayer crosstalk margins and servo recovery behavior, and evaluates the scalability of this carrier architecture toward layer counts in the thousands.
