ABSTRACT:
A modular rotary disc drive or disc file having three major subassemblies. These are a rotary actuator structure subassembly having an actuator housing and a pivotally mounted actuator member in said housing, an armstack subassembly including the transducer heads and their electric circuits including the plug terminal therefor, and a magnetic driver subassembly having a magnetic housing and a movable coil assembly. The armstack subassembly is attached and removed from the actuator member without removing the actuator member from the actuator housing. The magnetic housing of the magnetic driver subassembly is secured to the actuator housing and its moving coil assembly is secured to the actuator member. This magnetic driver subassembly is also attached and removed as a unit without removing the actuator member from the actuator housing.
