摘要： During recording or reading of data in an optical record carrier such as a disc, focus is optimized by adding a focus offset signal to the focus servo error signal. Each frame contains pre-formatted control marks in a servo field, and reference data marks recorded there at a time of data recording. The focus offset signal is optimized by spacing the reference data marks a distance as close as any data marks between which a zero or non-recorded position must be resolved, and taking samples of the optical readout signal as the optical scanning beam passes over or adjacent the reference marks. Four samples are used, taken between the peaks of the signal corresponding to the two reference data marks.

摘要： A method of determining coordinates for a storage medium includes: determining diffraction data from a plurality of diffraction patterns corresponding to diffractive markers of the medium; and combining the diffraction data to determine composite coordinates for the medium. The composite coordinates may include three translational coordinates and three rotational coordinates. The act of determining diffraction data may include shining a plurality of beams on a selection of the diffractive markers, and measuring the corresponding diffraction patterns in one or more photodetectors to determine the diffraction data. In this latter case the photodetectors may be segmented. The act of combining the diffraction data to determine composite coordinates may include solving a matrix system that couples the diffraction data and the composite coordinates. Each diffractive marker may include a pit. The storage medium may include a holographic storage medium.
