A method for modulating binary data into a format suitable for encoding and decoding information, that employs a non-return-to-zero (NRZ) technique. The modulating method includes: defining within a recording medium an event-cell as the time between two adjacent clock transitions having a similar, unique characteristic; and, selectively writing to the recording medium within the event-cell, at an arbitrary time, either a first or a second information. The selective writing step includes generating a first event and a corresponding first read signal in response to a first information and generating a second event and a corresponding second read signal in response to the second information. The method can be employed for a first situation where the information transfer rate during the modulating process is well-regulated, and is advantageously employed for a second situation where the information transfer rate is dependent on unpredictable and variable transfer rate velocities and accelerations.
