Efficient dc-free RLL codes for optical recording
We will report on new dc-free runlength-limited codes (DCRLL) intended for the next generation of DVD. The efficiency of the newly developed DCRLL schemes is extremely close to the theoretical maximum, and as a result, significant density gains can be obtained with respect to prior art coding schemes. With a newly developed DCRLL ( = 2) code we can achieve a 9% higher overall rate than that of ...

متن کاملEFM coding: Squeezing the last bits
Runlength-limited (RLL) codes have found widespread usage in optical and magnetic recording products. Specifically, the RLL codes EFM and its successor, EFMPlus, are used in the Compact Disc (CD) and the Digital Versatile Disc (DVD), respectively. EFMPlus offers a 6% increase in storage capacity with respect to EFM. The work reports on the feasibility and limits of EFM-like codes that offer an ...
متن کاملPerformance Investigation of Runlength- Limited Codes with Different d Constraints in Near-Field Optical Recording
This paper investigates the performance of runlength-limited (RLL) codes with different d constraints in near-field optical recording, for both the low-density parity-check (LDPC)-coded Bliss scheme and the standard concatenation scheme. Two state-independently decodable RLL codes, with d = 2, k = ¥ and d = 5, k = ¥ constraints respectively, are first designed for simulation. Both of these two ...
