Abstract
This invention relates to a time code recording and reproducing apparatus for recording and reproducing time codes corresponding to a digital signal. Time code converting means (100) converts a first time code into a second time code. A frame phase which occurs during the recording of input information is determined by frame timing generating means. A phase difference between a frame of the second time code and a recording frame is detected by phase difference detecting means (103). Phase difference correcting means (104) outputs a third time code on the basis of the detected phase difference. The input information is recorded together with the third time code. Thereby, the recording can be performed while the relation of the correspondence between the input information and the time code is held. In addition, the reproduction can be performed.
