<P>PROBLEM TO BE SOLVED: To provide a recording pulse generation device capable of forming a recording pit having a proper shape even in ultra-high-speed recording of, for example, 8 fold or higher recording speed. <P>SOLUTION: A recording controller 10 for generating recording pulse signals having lengths corresponding to ten kinds of lengths of pits formed in recording information has a recording controller 10 for generating the recording pulse signals so that the amplitude of a recording pulse signal corresponding to a pit having a length of 4T changes from a first amplitude to a second amplitude, and generating the recording pulse signals so that the amplitude of a recording pulse signal corresponding to a pit having a length of 5T or longer changes from a third amplitude to a fourth amplitude and further changes to the third amplitude. <P>COPYRIGHT: (C)2007,JPO&INPIT |
