This paper investigates the performance of runlength-limited (RLL) codes with different d constraints in high-density optical recording, for both the low-density parity-check (LDPC)-coded Bliss scheme and the standard concatenation scheme. For the d

In optical storage, data can be arranged on the disc in a meta-spiral consisting of a large number of bit-rows with a small track-pitch. Successive revolutions of the meta-spiral are separated by a narrow guard band. For high storage densities, such

A new scalar diffraction modeling method for simulating the readout signal of optical disks is described. The information layer is discretized into pixels that are grouped in specific ways to form written and unwritten areas. A set of 2D wave functio

For the optical recording channel, a new runlength-limited (RLL) code is proposed, called the 1102PC code,which is a d = 1 RLL code with a compact 2-to-3 PCWA-mapping for DC-control that oers a signicantperformance benet over traditional soft-dec

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 optical storage (TwoDOS) is a new concept that solves this data-rate

The paper introduces the concept of two-dimensional optical storage (TwoDOS). In this concept, bits are written in a broad spiral consisting of a number of bit-rows stacked together in a hexagonal packing. Bits with a value '1' are represented physic

Two-dimensional optical storage aims at increasing the data capacity and data rate for a given physical read-out system. It uses parallel read-out in combination with advanced signal-processing. Experimental results results on read only memory (ROM)
