Thanks! Those patents do actually explain their line of reasoning. If I got this right, they claim removing "0's", which exist to "fill" a system defined datablock, where there's less data then the actual storage blocksize, reduces timing errors because those "0's" are actually read and added as data in the datastream, causing jitter by changing the resultant data time domain.
Thank YOU for translating to layman's terms. This can then give me a mental Relationship to Embedded jitter, ie when HDDS are always shuffling around data for "efficiency" purposes, this may be adding "0" fills where none existed before? i know that SD cards dont do the shuffle.
