1. disc recording apparatus is used for by predetermined code, the supplementary concentric type of dish being recorded in the middle of a plurality of tracks of second area of described dish, rather than is recorded in the first area for the content-data that records described dish, comprising:

  • Rotate the whirligig of described dish;

    Generating means, for generation of the channel clock corresponding to an interval, this interval obtains by a frame being divided into k part that equates, wherein produce n piece, the length of each piece obtains by in a circumferential direction described second area being divided into n part that equates, and producing the m frame, the length of every frame obtains by being divided into m part that equates to each described in a circumferential directionWherein the pattern of frame synchronizing signal forms in the following manner;

    three or more channel bit in continuous arrangement mark or space, thereby described channel clock is that to record described supplementary in described second area needed;

    Control device is used for controlling the rotation of described dish, so that the described cycle synchronisation with n * m * k channel clock of circling of spiraling;

    Modulating device is modulated described supplementary according to the described channel clock that described generating means produces,Wherein said supplementary is modulated by the 4-1 modulator approach that is seven channel bit with two data bit modulation;

    AndPen recorder is used for the described supplementary of described modulating device modulation is recorded in described CD.
