VHD discs are 25 cm (9 5/6 inches) in diameter, and store up to 60 minutes of video per side. Each disc is stored in a plastic case, similar to a CED's case, so that the user could not touch the disc itself. The entire case was put into the player, which would take out the disc, and then the now empty case could be taken back out. After one side has finished playing, the disc would have to be taken out, flipped, and put back in to continue playing.
