Abstract
PURPOSE: To enable to perform special reproduction easily and surely, by giving a disc a part o which tracking guide grooves for a playback stylus detectig video signal information is formed, and a almost float part without the guide grooves.
CONSTITUTION: Two electrodes 351, 352 located on the track of the same pitch are placed on a reproduction stylus 35, which detects the video signal information from a video disc 31. That is, electrodes 351, 352 are located at the both ends toward the recording line of the video disc 31 on the main body 350 of the playback stylus 35. Further, the electrode 351 located at the arrow X being the progressing direction of the video disc 31 is provided so that it is located diased toward the arrow Y at the center side of the video disc 31 to the center line along the recording line of the video signal information track. On the other hand, the electrode 352 at the opposite direction with the arrow X is located biased to the arrow Z.
