High Quality Content by WIKIPEDIA articles! Video High Density (VHD) was a videodisc format which was marketed predominantly in Japan by JVC. There was also an audio-only variant, Audio High Density (AHD). VHD discs are 25cm (9 5/6 inches) in diameter, and store up to 60 minutes of video per side. Each disc is stored in a caddy—like the rival SelectaVision system from RCA, also known as CED, the user never handled the disc directly. The entire caddy is inserted into the player, and then withdrawn, leaving the disc inside where it will be loaded and start playing. At the end of the side the disc must be removed, turned over and re-inserted.
