Royal Netherlands Academy of Arts and Sciences. Archived from the original on 21 July Retrieved 17 July Lee Schouhamer Immink and K. Cai This paper proposes a general and systematic code design method to efficiently combine constrained codes with parity-check codes for optical recording. Weber Areas on Communications. The prior art construction of sets of balanced codewords by Knuth is attractive for its simplicity and absence of look-up tables, but the redundancy of the balanced codes generated by Knuth's algorithm falls a factor of two short with respect to the minimum required.

The performance of certain transmission and storage channels, such as optical data storage and non-volatile memory, is seriously hampered by the phenomena of unknown offset drift or gain. We report on 20 years of development of codes for optical disk recording systems. A description of the state-of-the-art and feasible options for future extensions and improvements are given.

Siegel, and Jack Wolf Constrained codes are a key component in digital recording devices that have become ubiquitous in computer data storage and electronic entertainment applications. Proceedings of the IEEE. Coding techniques are used in communication systems to increase the efficiency of the channel.

A few years later, he was a technical leader in negotiations between Sony and Philips that led to industry standards for the compact disc. During his long career at Philips Research Laboratories, Immink he served in many capacities in various research groups including Electronic Systems, Optics, and Magnetic Recording Systems. In he was appointed a Philips Research Fellow.

Immink is the author of Coding Techniques for Digital Recorders, which has become the standard reference book of the field. He has also written several papers, articles, and book chapters. Explore Browse by Subject. Oral Histories.

First Hand Histories. Personal Narratives. The encoding system Immink devised came to be called eight-to-fourteen modulation EFM. In the article, "Shannon, Beethoven, and the Compact Disc", Immink presents a historical review of the years leading up to the launch of the CD, and the various crucial decisions made. Commercial disputes also played a part.

After the CD standard was set inImmink and his co-workers conducted pioneering experiments with magneto-optical audio recording on pre-grooved discs. They also found a simple method to extend the analog videodisc standard with digital sound. Laserdiscs fabricated after have digitally encoded sound signals. Immink was a member of the Philips and Sony task force, which developed a competing disc format, called MultiMedia CD.

The electronics industry feared a repeat of the format war between VHS and Betamax in the s. Immediately after the DVD standard was settled inPhilips and Sony, disappointed after the DVD failure, decided to develop a next-generation blue-laser-based digital video recorder DVRwhich would be positioned as DVD's high-density successor. Philips and Sony set up a joint task force, where Immink and his co-workers developed DVRs, later called Blu-ray's, code design.

Inseven years after its design, the Blu-ray Disc was brought to market. The two resulting standards had significant differences that made each incompatible with the other. The blue-laser format war with Toshiba's HD DVD was settled in early when Toshiba withdrew their system effectively ending the high definition optical disc format war.

InImmink joined Philips's magnetic recording group, where he contributed to the design of coding technologies of the digital video tape recorder, DV and the Digital Compact Cassette DCC. The DCC was short-lived: introduced in and discontinued in Konstantin Zvorykin. Bela Barenyi. Ferdinand Porsche. Sergo Beria. Emil Shkoda.
