This invention relates to a time code recording/reproduction apparatus for recording and reproducing a time code corresponding to a digital signal. Time code conversion means (100) converts a first time code to a second time code and frame timing generation means determines a frame phase used when the input information is recorded. Phase difference detection means (103) detects the phase difference between the frame of the second time code and a recording frame and phase difference correction means (104) outputs a third time code on the basis of the detected phase difference and the input information is recorded together with the third time code. Accordingly, the input information can be recorded or reproduced while its relationship with a corresponding time code is being retained.
