Koninklijke Philips Electronics, Michael E Belk, January 2, 2007: US07158060 (8 worldwide citation)

How to record and play back data at a high line density. A DSV control bit determining/inserting unit 11 inserts DSV control bits for execution of DSV control into an input data string and outputs the data string including the DSV control bits to a modulation unit 12. The modulation unit 12 converts ...

To obtain a detector which has considerably less complexity than a Viterbi detector without a loss of performance, there is proposed to use a code that makes it possible to distinguish types of transmission errors. As a result of this distinction of types of detection errors, there may be establishe ...

The life of a rewritable information carrier such a CD-E covered by a phase-change recording layer is extended by varying the manner of representing information of an information block, for subsequent recordings, in the same portion of the record carrier. The manner can be changed, for example, by s ...
