Abstract: A system for processing a disk includes an end-effector having a plurality of fingers. The end-effector is mounted to a rotary actuator. The rotary actuator is mounted to a linear stage. The linear stage is positioned adjacent to an air track and a tank. The rotary actuator and the linear stage place the fingers into the inner diameter of a disk on the air track. The fingers grip the inner diameter of the disk. The rotary actuator and the liner stage then place the fingers holding the disk into the tank. The tank is filled with a processing liquid such as a lubrication solution to lubricate the disk.

Abstract: A sputter pallet loading and unloading device includes in one embodiment a spindle that rotates the pallet while an arm is engaged with the spring in the pallet to open and close the spring. In another embodiment, the spindle is located adjacent an air track that moves the disk substrate over a cushion of air to the loading area of the pallet. The air pressure under the disk substrate is increased to raise the disk substrate into the loading area. Once raised into the loading area, the spring is closed, e.g., by rotating the pallet in the opposite direction. The pallet and air-track are at a small angle to allow the substrate to slide into the correct position. The simplicity of operation leads to a reduced cost and a higher throughput for this device compared to a robotic loader.

Abstract: A washer includes driving and scrubbing rollers that press against the opposing surfaces of a substrate, which may be, e.g., a small form factor disk. The driving rollers and scrubbing rollers are approximately aligned along two different radii of the substrate that are separated by 180 degrees. The driving rollers rotate in opposite directions as do the scrubbing rollers. During the scrub cycle, the driving rollers cause the substrate to rotate, while the scrubbing rollers scrub the opposing surfaces of the substrate. Outside diameter rollers that are orthogonally positioned relative to the driving rollers and the scrubbing rollers, and which may be free spinning, contact the outside diameter of the substrate and hold the substrate in position during the scrub cycle. The substrate is loaded into the washer by lifting the substrate, via a lifting arm, to the driving and scrubbing rollers.

Abstract: A silicon nitride self-lubricating layer forms the upper surface of a data storage disk. The silicon nitride self-lubricating layer can replace the carbon protective overcoat and liquid lubricant used in conventional data storage devices in which an aerodynamic slider is supported by an air bearing by providing both physical protection for the underlying recording layer and lubrication between the slider and the disk.
