ABSTRACT:
An improved method and apparatus for encoding data prior to storage on a disk or other magnetic media is disclosed which features comparison of input data patterns with stored data patterns in a programmable logic array or other logical mapping structure and outputting of uniquely encoded patterns of flux transitions to be written to said magnetic media based upon the results of the comparison. The apparatus additionally comprises means for serializing the data to be written and deserializing data upon reading from the media.
