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