ABSTRACT:
The present invention is directed to an improved method and apparatus for encoding binary data by which an improved sequence of encoded binary digits suitable for the NRZI modulation to produce a recording signal is obtained. The improved sequence of encoded binary digits obtained according to the invention consists of a plurality of binary digit blocks, each of which is formed with a predetermined number of the encoded binary digits obtained from the binary data and plural redundant codes, each of which is inserted between each successive two of the binary digit blocks, and can produce the recording signal forming a rectangular pulse train with the waveform which has the long minimum run length and does not contain the DC component or contains the diminished DC component therein when it is modulated in the NRZI modulation. By use of such a recording signal, high data density recording with a recording signal transmitted without distortions in its waveform can be achieved.
