ABSTRACT:
The present invention relates to a method of recording and reproducing data on a recording medium, wherein original data is recorded on a recording medium by converting it into a code having more than one "0" between bits "1" such as MFM code and RLL (1,7) code, and a timing of a zero-cross of a reproductive signal or a second order differential signal from the recording medium is detected to obtain a bit "1" and reproduce the original data. The method allows to avoid affect of interference between marks and to record and reproduce data at high recording density and with high reliability.
