Abstract:
1. A method of encoding data values with data codes and control codes, comprising the steps of: in response to each different eight bit data value, generating a corresponding 10-bit encoded data value, each 10-bit encoded data value having an absolute disparity value for all 10-bits of no more than 2; and in response to each of a plurality of control code select values, selecting a 10-bit control code from a set of at least sixteen 10-bit control codes, each 10-bit control code being different from the 10-bit encoded data values and having an absolute disparity value for all 10-bits of no more than 2, and an absolute disparity value for a first six bits of no more than 2, each 10-bit control code having particular bit values in response to a first running disparity value, and a complement of said bit values in response to a second running disparity value.
