Abstract
A detector system detects values on a storage medium where there is ISI. The symbols are stored as pits in a close hexagonal lattice having u, v, and x dimensions at mutual 60° separations from an individual pit. The value for a particular symbol is determined by generating an estimate for the symbol in each of the u, v, and x dimensions. These estimates are used to generate a decision for the symbol as it is at the intersection of these dimensions. Thus a number of 1-dimensional detectors can be used although the platform is two-dimensional with ISI.
