ABSTRACT:
A cartridge for a video disc stylus having a stylus-position sensor, including an electrode mounted to the cartridge walls. An appendage is provided on the cartridge wall to position the sensor electrode proximate the stylus, the appendage being contoured to accept a preformed sensor electrode. The sensor electrode is formed from sufficiently resilient material to recover from deformation during electrode-appendage engagement and constrain itself to a particular position in the cartridge by compressive forces developed between the electrode and the appendage.
