Abstract

PURPOSE: To reduce static friction of a slider that comes into contact with a disk face by forming, on one side of the slider, a rail provided with a spread of an air supporting face fronting on the recording face, and at least one landing pad containing a landing facet in that spread. CONSTITUTION: The escape area 22 of a slider 20 controls a rail 24 lapped and polished to a mirror finish for the purpose of forming an air supporting face 26 (imaginary line). The air supporting face 26 of the slider 20 is pattern- plotted, forming an escape air supporting face 26a (continuous line), which is equipped with one or more projection or a landing pad 34 having a face (facet), a remainder of the air supporting face 26 before the plotting. In addition, a read/write head 30 is formed at the other end of the slider 20, with its extreme tip end properly contained in the boundary of the landing pad 34. As a result, only a small part of the slider rail 24 area is brought into contact with the disk face, enabling static friction to be reduced.

A problem that has plagued many devices in the past, particularly hard disk devices, is a problem known in the art as staking. This problem is particularly acute when the flat, highly polished surface of the slider's rails (typically a pair) is in intimate contact with the flat, highly polished surface of the stationary disk. Large-area intimate contact under load is magnified by the presence of contaminants or organic films, which are characterized by extremely high adhesion forces. Stake, the unfavorable tendency of the air bearing surface to stick to the disk, occurs in this situation because of the extremely large area of surface contact that exists between the slider rail and the disk surface.

Stake is a serious problem because it makes it difficult, if not impossible, to start the spindle motor. Unfortunately, such activation can result in various actual damages, such as scratches on the disk surface, or even the read/write head structure itself being pulled from its support mechanism.

One industry solution to the staking problem is to
It involves intentionally texturizing (grooving) the initial highly polished disk surface. The purpose is to minimize the contact area between the disk surface and the slider rail. Textured surfaces tend to wear more rapidly in contact with the rails, create particulate contamination, and progressively degrade air carrying performance. Additionally, texturing is unpredictable and not repeatable from disc to disc.

To solve the problems caused by texturing, a surface lubricant is applied to the surface of the disk. This also presents serious difficulties. In particular, lubricants do not always completely eliminate slider wear. As slider wear progresses, wear products combine with lubricants and other organic materials to fill the textured grooves to the extent that serious staking is resumed. Additionally, a mixture of these contaminants adheres to the air bearing surface of the slider, reducing air bearing performance.

Preferably, an air bearing surface on each rail of the slider having two or more landing pads is employed. In this configuration, only a small portion of the area of the slider rail contacts the disk surface, greatly reducing staking.

The extent to which relief is formed by etching on the initial air support surface is
Determine the difference in height of the landing pad above the newly formed air support surface. This height difference is due to the need to provide minimal clearance for parts of the slider (other than the landing pad) to contact the surface of the disc to minimize pad wear, the disadvantageous loss of air support stiffness, and the disadvantageous loss of air support stiffness and aerodynamics. This is balanced by the need to avoid excessive escapes that would lead to a decrease in the reliability of the system. The effective flight height of the landing pad, particularly at the trailing edge of the landing pad, is reduced by an amount approximately equal to the amount of air support surface relief, thus achieving the effective flight height of the transducer location, a typical design parameter. It is necessary to compensate for the rail width. Experience has shown that about 13 microinches of cutout is compatible with the above limitations, and that landing pad wear after 10,000 or more start/stop cycles is typically a fraction of a microinch. It has been found that.

A preferred embodiment of the invention employs two to three pads on each rail, each pad projecting an area of about 5 x 101 inches. including the head within the landing pad at the rear end of each rail, as described above, and locating the landing pad on each rail near the front of the rail just behind the line defining the initial air support surface and ramp; In this way, a straight line shape is used. If desired, one or more landing pads can be located between the front and rear landing pads. This allows the slider's contact area with the disk surface to be reduced by more than two orders of magnitude from conventional designs. This minimizes staking by limiting and precisely controlling the effective contact area of the slider disc.

Although the slider design proposed in this invention offers significant advantages when using typhus-processed media (with or without lubricants), the preferred embodiment does not use organic lubricants. Employ a medium that has a surface that will not be used or textured. The elimination of textured grooves created by mechanical friction allows for great control over the quality of the media surface, which becomes increasingly important as head flight height is reduced to achieve good recording performance. . In addition, high yield of non-textured disks,
Can be manufactured at low cost. Removal of organic lubricants also simplifies media manufacturing and, most importantly, greatly reduces staking problems resulting from the need to overcome the very high shear characteristic of thin organic films.
