Patent ID: 7995675

Claim:
A method to communicate information within a data storage library comprising a plurality of enclosures, comprising the steps of: defining and saving a first waveform comprising a frequency F B ; defining and saving a second waveform comprising a frequency F 0 , wherein said second waveform is decoded to mean a bit comprising a first value, wherein said frequency F 0 differs from said frequency F B ; defining and saving a third waveform comprising a frequency F 1 , wherein said third waveform is decoded to mean a bit comprising a second value, and wherein said frequency F 1 differs from both said frequency F 0 and said frequency F B ; and transmitting by an initiating enclosure a byte of data encoded as eight data waveforms, wherein each of the eight data waveforms comprises said frequency F B in combination with either said frequency F 1 or said frequency F 0 .
