Encyclopedia
Peter A. Franaszek is an American information theorist, an IEEE fellow, a research staff member emeritus at the IBM T.J. Watson Research Center and a former member of the IBM Academy of Technology
. He received his Sc.B. from Brown University in 1962, and his Ph.D. from Princeton University in 1966.
His work was mainly on the representation of information for storage and transmission, and the placement and movement of such information in computer systems. Specific areas include constrained coding, compression algorithms, I/O architectures, switching networks, disk defragmentation algorithms, concurrency control techniques, operating system schedulers, and compression techniques and architectures for systems with memory compression. Franaszek's coding research determined fundamental aspects of constrained coding, and obtained algorithms for code construction. His work served as a basis for key components in the proliferation of disk drives, compact disks (CDs), and digital versatile disks (DVDs). Specific codes he developed have been widely used in commercial data storage and transmission products. His (2,7) RLL code found widespread application in disk drives in the 1980s and later in magnetic and optical recording applications. Together with Albert Widmer, he designed 8b/10b encoding

8B/10B encoding
In telecommunications, 8b/10b is a line code that maps 8-bit symbols to 10-bit symbols to achieve DC-balance and bounded disparity, and yet provide enough state changes to allow reasonable clock recovery. This means that the difference between the count of 1s and 0s in a string of at least 20 bits...
