    • There is provided a recording pulse generation device capable of forming a recording pit of an appropriate form even at an ultra-high-speed recording such as the standard speed multiplied by eight or more. The recording pulse generation device includes a recording control unit (10) for generating a recording pulse signal having a length corresponding to respective pit lengths when information is recorded by forming pits of 10 or more length types. The recording control unit (10) generates the recording pulse signal in such a manner that the amplitude of the recording pulse signal corresponding to the pit having length 4T varies from a first amplitude to a second amplitude and generates the recording pulse signal in such a manner that the amplitude of the recording pulse signal corresponding to the pit having length not smaller than 5T varies from a third amplitude to a fourth amplitude.

    • PURPOSE: An optical recording medium, an optical recording medium manufacturing apparatus, and an optical recording medium manufacturing method are provided to secure an optical recording medium capable of getting a radial push-pull signal to whole disk area and keeping actions of a servo circuit of a recording-reproducing apparatus stable. CONSTITUTION: An optical recording medium(10) comprises groove tracks(11) including a first area(Ba) for recording record information and a second area(Ca) in which predetermined data is formed as embossed pit rows(19) and a readout of other data overwritten and recorded on the embossed pit rows is prevented, and land tracks(12) formed between the adjacent groove tracks. A depth(Ed) and a duty of the embossed pit rows are set so that a radial push-pull signal in the first area and a radial push-pull signal in the second area become the substantially same level.
