Abstract
Method and apparatus is described for encoding and decoding a stream of randomly distributed binary bits representing digital data, including an encoder for encoding the bit stream to achieve a run length limited, partial response coding of the stream; a recording medium for recording the encoded stream; and a decoding system for recovering timing signals and a stream of data signals separately from the recorded stream using a first channel for decoding the recorded stream to recover a timing signal stream; therefrom; and a second channel for decoding the recorded stream to recover a stream of data signals therefrom.
