A recording disc and a recording device capable of preventing an unauthorized copying. In a reproduction control data region where pits of a pit string carrying reproduction control data indicating a reproduction control method when reproducing information data are recorded in such a manner that they are aligned in a plurality of adjacent tracks in the direction orthogonal to the tracks, a unit interval length on a track corresponding to one bit of the generation control data is made shorter than the twice of the rotary jitter length generated when the spindle motor is rotated by the control method using a frequency generator FG.
