Abstract:
1. A data storage device comprising: a magnetic transducer including a read and a write head for reading and writing magnetic transitions; a magnetic thin film recording medium; means for moving the recording medium in relation to the magnetic transducer; a first sensor having an output indicative of a need for an additional amount of lubricant on the recording medium; a lubricant dispenser comprising a lubricant reservoir housing with an aperture and a movable shutter having at least first and second positions with the first position covering the aperture to prevent lubricant vapor from escaping and the second position uncovering the aperture allowing lubricant vapor to escape; an actuator that selectively moves the movable shutter between the first and second positions; and a controller connected to the sensor, the controller being responsive to the output of the sensor by signaling the actuator to move the movable shutter to the second position uncovering the aperture allowing lubricant vapor to escape.
