処理D40にて Tre＝Tim−Tdr と補正することができる。Furthermore, the video or audio of the magnetic recording medium loaded in the reproducing magnetic recording device 31 or the recording magnetic recording device 32 is reproduced at an arbitrary speed, and the operator monitors the image or the sound on the monitor A41 or the monitor B42 while editing the data. position of the magnetic recording medium when pressing the button 36 of the controller 33 at the beginning and end of the detection process A37 (hours T im) of the control device 33, detection of the reproduction speed V a of the control unit 33 of the magnetic recording medium It measures in processing B38. By the standard playback speed V n Here the magnetic recording medium, T dr = (T d1 + T d2) is deviation time T dr of the beginning or end of the editing section on the magnetic recording medium by the correction processing C39 × (V a / V n ). Therefore, the start or end time T re of the section where editing should be performed can be corrected to T re = T im −T dr in the correction processing D40 from the start or end time T im of the actually registered section. .
