Abstract
A disc drive includes a cartridge holder formed of a single piece of sheet metal which cooperates with a slide plate which is similarly formed of a single piece of sheet metal. The sides of inclined guide slots formed in side walls of the slide plate are parallel and serve to guide horizontally projecting flange-like guide members of the cartridge holder. A single piece disc shutter control arm is pivotally mounted in the cartridge holder and motivated by the force which moves the disc cartridge into the disc holder in a manner which opens the disc cartridge shutter. The chuck yoke of the turntable is provided with an inertia increasing annular member. A head is mounted on a pivotal head arm which is operatively connected with the cartridge holder in a manner to be pivoted up and down therewith. A head carriage is released and operatively connected with a motor upon the cartridge holder being lowered past the level whereat the disc hub of the disc in the disc cartridge is placed on the chuck yoke and the head is placed on the upper surface of the disc.
