Claims

[Scope of utility model registration request]

In a video disk cartridge, a needle is held at the tip of the cantilever, the base of the cantilever is pivotally supported by a cartridge case via a rubber damper, and the rear end is fitted into an electromagnetic actuator for tracking and jitter servo. has a base that is bent in a substantially crank shape in the vertical direction and whose upper side is pivotally supported by the cartridge case via a rubber damper, and a base that is connected to the tip of the lower side of the base via a leaf spring damper and is attached to the disk surface. A cartridge for a video disc characterized by comprising a stylus attachment part extending at a slight angle with respect to the cartridge.
