ABSTRACT:
A method for recording digital data for recording and reproducing data at a high transfer rate. A recording basic clock is generated which synchronizes with the reference clock previously recorded on an optical recording medium and has the same frequency as the basic clock of data to be recorded, the recording signal is generated in which the phase of recording basic clock is slightly shifted corresponding to the data to be recorded, and the data is recorded on the optical recording medium by modulating a laser beam by the recording signal. Therefore, it is possible to realize a method for recording digital data, a digital data recording apparatus and a digital data recording/reproducing apparatus capable of recording data with a simple constitution at a high speed when a data is optically recorded by shifting the edge position of information pit stepwise from the predetermined reference position in accordance with the recording information.
