Abstract
A sector in each track of a moving memory recording media includes recordings defining a synchronizing field and a start of data field. Selected bit signals of bit signals derived from recordings are simultaneously combined in a plurality of differing bit signal combinations. The simultaneous existence or validity of all of the bit signals in each of a predetermined number of differing bit signal combinations, which predetermined number is less than the plurality of bit signal combinations, provides fault tolerant detection of start of data field.
