Magnetooptical disk unit capable of recording or reproducing signals having different domain lengths under the same conditions, signal recording method and signal reproducing method

Image Number 10 for United States Patent #6295253.

When recording a recorded signal consisting of "01011001110" in a magnetooptical recording medium, (1,1) corresponding to a domain of 2T is converted to (1,0,1), and (0,0) is converted to (0,1,0) in the recorded signal. In other words, the first "1" of (1,1) is converted to unit bits "1,0" and the first "0" of (0,0) is converted to unit bits "0,1". Similarly, the first "1" of (1,1,1) corresponding to a domain of 3T is converted to unit bits "1,0", and the second "1" is converted to unit bits "1,0". "1" or "0" of the final unit bit is not converted but recorded as such. Consequently, a signal can be correctly reproduced by extension ally transferring domains having different domain lengths from a recording layer to a reproducing layer under the same reproducing conditions.
