TH7634B - Integrated lubrication fluid delivery system for aircraft in the magnetic disk storage system - Google Patents

Abstract

Head hanging system - combined filling with lubrication That includes a bearing area at one end that holds the magnetic transducer opposite the recording plate. This invention provides a fluted groove with filament absorption in the integrated filament hanger. The grooves are shaped to create a small hole attraction. To pull the lubricant from the supply line on the sleeve along the suspension of the bearing area. This ensures that the disc area under the head does not dry out regardless of the time slot and storage conditions. When the recording disc is rotating, the filling continues to deliver lubricant to the surface of the recording disc.

Claims (20)

1. In a system for delivering lubricating fluid to the read/write head-disk linkage of the slider positioned at the end of the drive rod assembly for use with a magnetic disk storage unit, improvements include: a. A fluid reservoir adjacent to the edge of the magnetic disk to drain small fluid droplets splashed from the edge of the disk; b. A small-bore device extending along a section of the so-called side assembly to the side of the so-called slider that supports the disk; this small-bore device contains various small holes in the so-called drive rod to transport the lubricant to the vicinity of the disk for accumulation on the disk surface; c. A filament extending from the so-called fluid reservoir to the inner end of the so-called groove; and d. The lubricating fluid contained in the reservoir is adjusted to be transported by the filament to the end of the so-called filament device, and from there it is transported by the so-called filament device to the section of the so-called slider that supports the disk surface. 2. The system under Claim 1, whereby the so-called lubricating fluid is a low-viscosity fluid in which a lubricant at the high-pressure boundary is dissolved. 3. The system under Claim 1, herein referred to as the reservoir, consists of a surrounding enclosure and a peripheral area called the recording disk. 4. The system according to claim 3, where the so-called lubricating fluid exhibits a concave shape in the area between the so-called sliding surfaces of a recording disc when such recording disc is stationary. 5. The system under claim 4, whereby the so-called concave shape, when formed, provides a condition for blocking the further flow of lubricating fluid through small holes in what is called a micro-hole device. 6. The system under claim 5 herein, called the concave shape, is destroyed by the rotational condition of the so-called surface of the recording disc to allow the continuous flow of the lubricating fluid through the so-called perforated device to the so-called slider, which is supported against the so-called surface of the recording disc. 7. The system under claim 1, herein referred to as the "bottom reservoir" to the "inner end" of the "small hole" device, shall be flexible enough to allow the movement of the "actuator rod" to be independent relative to the reservoir. 8. The system under claim 1, herein referred to as a micro-hole device, consists of a groove cut out in what is called a shank. 9. The system under claim number 8, herein referred to as the slider and the part referred to as the actuator rod, which conveys the various small holes, is a single integrated structure. 10. The system under claim 2 herein referred to as a low-viscosity fluid is hexadecane, and the system referred to as a high-pressure boundary lubricant is stearic acid. 11. The system under claim 10 herein, referred to as low-viscosity fluid, comprises 99% by weight, and the system referred to as marginal lubricant comprises 1% by weight. 12. The system under claim 11 herein referred to as the low-viscosity fluid is perfluorexane, and the system referred to as the high-pressure boundary lubricant is the reactive n-group perfluoropolyether. 13. The system under Claim 1 herein, the reservoir, consists of a fiber device. 14. A rotating memory device consists of: a. The rotating storage medium, which represents the rotating data surface; b. The drive rod, which is integrated into a single unit and includes a section for transporting the liquid lubricant; c. A device for maintaining the circulating film of liquid lubricant on the so-called data surface, which has a device with small holes in the so-called drive rod to transport the lubricant to the vicinity of the medium for deposition on the surface of the so-called rotating storage medium; and d. The so-called converter, which is supported above the so-called rotating surface, with the so-called film of liquid lubricant when data is written to or read from the so-called rotating data surface. 15. The rotating memory device of claim 14, herein referred to as the hard disk medium, is a hard disk drive. 16. The rotating magnetic memory device of claim 14, herein called the rotating film holding device, consists of a device for handling and rotating, called the liquid lubricant on, called the data surface. 17. The rotating memory device of claim 16 also includes a read/write-disc enclosure which surrounds what is called a rotating storage medium called a magnetic converter. 18. The rotating memory device of claim 17, herein referred to as the enclosed device, shall be sealed, herein, to the rotating data storage medium and to the herein, to the magnetic converter, preventing air from the surrounding atmosphere from entering. 19. The rotating memory device of claim 16 herein, called the rotating device, is lubricated with a liquid lubricant on the data surface and consists of a porous material covering the disk enclosure. 20. The rotating memory device of claim 16, herein referred to as the fluid lubricant circulation device, consists of a filament for moving the fluid lubricant to a filament called a rod, which is integrated into a single unit.
