ABSTRACT:
An information recording method in which an energy beam is irradiated to a recording medium and a basic recording pattern is generated. The basic recording pattern has a first power level provides a first state and a second power level providing a second state. Based upon a period of a recording timing generating clock in a recording mode, and a relative velocity of the energy beam and the recording medium, there is formed a first sequence of the second state and the first state based upon parameters as a first small recording pattern, a second sequence which starts with the first state and ends with the first state as a second small recording pattern, a state in which the second small recording pattern follows said the small recording pattern as the basic recording pattern, and a state in which the basic recording patterns are repeated as a recording pattern.
