In 1979, JVC demonstrated a prototype of its video high density (VHD) disc system. This system was capacitance-based, like capacitance electronic disc (CED), but the discs were grooveless with the stylus being guided by servo signals in the disc surface. The VHD discs were initially handled by the operator and played on a machine that looked like an audio LP turntable, but JVC used caddy-housed discs when the system was marketed. Development suffered numerous delays, and the product was launched in 1983 in Japan, followed by the United Kingdom in 1984, to a limited industrial market.
