Abstract: A LUBRICANT RESERVOIR SYSTEM FOR A MAGNETIC DISK NEAR CONTACT DATA STORAGE DEVICE, WHICH ROTATES IN UNISON WITH THE DISK ASSEMBLY TO REPLACE LUBRICANT DEPLETED FROM THE DISK SURFACE OVER THE LIFE OF THE DEVICE, INCLUDES RESERVOIR CHAMBERS IN DISK SPACERS WITH LUBRICANT METERING PROVIDED BY RESTRICTED PASSAGES OR TEXTURED SURFACES EXTENDING RADIALLY OUTWARD FROM THE RESERVOIR CHAMBER WHILE REPLACEMENT AIR PASSAGE EXTEND RADIALLY INWARD TO REPLACE DISPENSED LUBRICANT. THE METERED LUBRICANT IS DELIVERED TO THE DISK SURFACE AT A LOCATION WHERE THE SURFACE CONFRONTING THE DISK IS MADE COMPLIANT WITH THE DISK SURFACE AND THE ADJOINING SURFACE IS BEVELED TO FORM AN ANGLE OF MORE THAN 90 DEGREES WITH THE DISK SURFACE THEREBY PREVENTING MIGRATION OF LUBRICANT AWAY FROM THE DISK. NONWETTABLE SURFACES MAY BE USED IN METERING PASSAGES, AIR PASSAGES, AND ON SOME BEVELED SURFACES TO FURTHER CONTROL LUBRICANT METERING. IN OPERATION, THE HIGH G FORCES INDUCED BY ROTATION CAUSE LUBRICANT TO BE METERED TO THE DISK WHILE THE SAME SMALL METERING PASSAGES FUNCTION AS A BARRIER WHEN THE DISK ASSEMBLY IS NOT ROTATING.

Abstract: THE BACK EDGE OF A DISK DRIVE SLIDER IS USED TO REMOVE DEBRIS FROM DISK MEDIA BY SLOWLY SWEEPING IT FROM THE INNER DIAMETER OF THE DISK TO THE OUTER DIAMETER OF THE DISK WHILE THE DISK IS ROTATING BACKWARDS FROM NORMAL. THE SWEEPING OPERATION IS COMPLETED WHILE THE DISKS ARE STILL GAINING ROTATIONAL SPEED SO THAT LIFTOFF VELOCITY IS NOT ACHIEVED. MATERIAL ACCUMULATED ON THE BACK EDGE OF THE SLIDER IS EITHER DUMPED AT THE OUTER DIAMETER OF THE DISK, OR REMAINS ON THE BACK EDGE OF THE SLIDER AS NORMAL OPERATION IS COMMENCED.(FIG. 4)
