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. In early work associated with his "principal state" technique for block code construction, he designed MS43, a ternary code for data transmission, a modified version of which, MMS43, became a European standard. His work also 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 used in gigabit telecommunication systems.
