Coherent interlayer cross talk and stray-light intensity of multilayer read-only-memory (ROM)
optical disks are investigated. From results of scalar diffraction analyses, we conclude that …

With storage capacities increasing much faster than data rates, fast read-out of content is
becoming a bottleneck for the convenient use of optical storage devices. Two-dimensional …

Near-field recording using an actuated solid immersion lens is an attractive solution for a
next-generation optical storage product. By applying advanced servo techniques, like feed …

We advocate the use of a polymeric cover layer for protecting the data layer and the tip of the
solid immersion lens in near-field optical recording system. With a cover on top of the data …

We present the status of our efforts to demonstrate the feasibility of recording on a cover-
layer protected dual-layer optical disc with a blue laser and NA= 1.45 objective lens that is …

This paper proposes a general and systematic code design method to efficiently combine
constrained codes with parity-check (PC) codes for optical recording. The proposed …

For high-density optical recording systems, the effectiveness of the partial–response
maximum-likelihood (PRML) detection scheme is limited by the channel asymmetry. Hence …
