Abstract
An information recording method using a recording medium having a first state by a first power level of an energy beam and a second state by a second power level of the energy beam higher than the first power level. When a period of a recording time generating clock in a recording mode is T, and a relative velocity of the energy beam and the recording medium is V, the method includes forming a sequence of the second state with length avT (first mark), the first state with length ivT (first space) following the first mark, the second state with length mvT (second mark) following the first space, the first state with length jvT (second space) following the second mark and the second state with length bvT (third mark) following the second space as a first small recording pattern.
