Hereinafter will and be described in detail with reference to the accompanying drawings in conjunction with embodiments of the invention.
The first embodiment of the present invention will be illustrated referring to figs. 1 to Fig. 3 and Fig. 5.Fig. 1 is a perspective representation one a title portion sliding shoe bracing or strutting arrangement.This head sliding shoe bracing or strutting arrangement comprises 11, one gimbal spring sections 12 of a pendulum spring part, and a read/write head is installed on the gimbal spring section 12.This head sliding shoe bracing or strutting arrangement is that the surface along recording medium swings back and forth, this is by a manhole mechanism that a drive part arranged, this gimbal spring section 12 is and terminal adjacent the forming of the rigid element of pendulum spring part 11, and a sliding shoe 13 is mounted in above the gimbal spring section 12.On the other hand the side of the most approaching end of pendulum spring part 11 connector 18 in a manhole mechanism in place like this can and manhole mechanism binding, the rigid element 14 of pendulum spring part, spring section 15, reaching gimbal spring section 12 all is to be formed by monoblock thin plate 10, for example rolled plate.Rigid element 14 is thin plate 10 those parts between floor 16 both sides of the longitudinal direction of pendulum spring part 11.Between floor, be provided with a wiring board 17 on rigid element 14, this is the circuit that signal is provided for magnetic head.Sliding shoe 13 has the axial surface of an air layer, this is to say at the surface that recording medium is arranged, each surface leave recording medium this to be so unsettled power of being caused by a unsettled power caused by the rotation of recording medium and another distortion owing to spring section 15 causes what loading force caused, at this moment require the mutual balance of this two power.
Fig. 2 is gimbal spring section 12 and near enlarged drawing thereof.This gimbal spring section 12 comprises 1 sliding shoe connector part 19 and a gimbal retractility part 20.A sliding shoe 13 has read/write head 21, installs and is attached on the sliding shoe connector part 19 and in gimbal spring section 12, supported by a gimbal telescopic section 20, makes not to be soft at grade and to be rigidity in same plane.Yet the lead-in conductor (not shown) is divided into two groups by gimbal telescopic section 20 enters sliding shoe connector part 19, and they are directed to lead end part 27 more then by to each end portion (not shown) of slider.
Fig. 3 is that the rigid element 14 of the sectional view direction of arrow of taking from Fig. 2 is along profile line III-III.Floor 16 be the one side by thin plate 10 form by coating and plate 10 be rolled plate this be an example.Coating can be by plating, and the spraying steam is coated with formation, also has CUD or is formed by the glass or the pottery of sintering.
According to above-mentioned structure, the thickness of floor 16 can surpass thickness spring section 15 or gimbal spring section 12, so just can make the desired rigidity of acquisition of rigid element 14.Also has material as gimbal spring section 12, it is can be rolling come out and do not need to add in addition processing (for example one the 25 non magnetic rolled sheet metal sus 304 of micron thickness has thickness accuracy, less than ± 1 micron error) that such thin plate has high-precision thickness as rolled plate.So just can provide the title portion sliding shoe bracing or strutting arrangement rigidity that it has a little level residual quantity to tackle one around parallel with recording medium as a turning axle, and perpendicular to the vibration of the axle of the longitudinal direction of head sliding shoe support component, and little rolling has just been verified and is paid one and be parallel to recording medium around one, and perpendicular to longitudinal direction the axle vibration, variation differential like this and rolling rigidity can reduce.So the variation of the quick condition of sliding shoe 13 can reduce widely, the characteristic subsequently at the recording medium surface can improve like this.This also comprises pendulum spring part one-piece construction together the one-piece construction of gimbal spring section 12, can prevent that read/write head 21 is offset from track.
Because pendulum spring in this embodiment partly has its lead-in wire of a rigid element 14 owing to provide thin plate 10 to have floor 16, thin plate 10 can reduce at the thickness of pendulum spring part 11 like this.The relation that Fig. 4 is a diagrammatic representation between the flange on the pendulum spring part 11 " h " height and floor " h ' " height, highly " h " requires to obtain not in conplane rigidity it and is complementary with flange and quite.This figure has represented that calculated value is based on hypothesis, last binding floor 16 has in fact the identical mechanical property of the thin plate made with rolled plate 10, for example, if flange thickness is 0.076mm and highly is 0.7mm, just can understand like this from scheming to go up, the width of floor is the about 0.2mm of depth of floor that 1-2mm requires, and in other words depth of floor is 30% of flange height approximately.In the method, adopted floor, by increasing floor 16 width, rigidity in the same plane can increase, so just can realize, this can realize the high-frequency natural vibration of the same plane mode of head sliding shoe bracing or strutting arrangement, at first embodiment shown in Figure 11 in order to avoid increasing the thickness of pendulum spring part 11, adopted a wiring board 17 for example its thickness of a printed-wiring board (PWB) be to wait or, come to be the read/write head wiring less than floor thickness.The lead that extends out from wiring board 17 is loosening state, and reason is an elastic telescopic of having considered spring 15 parts.Coating has been adopted in the formation of head slider bracing or strutting arrangement, and its manufacturing cost has just lowered.
Another technological process that forms floor 16 plates is at first to plate one deck homogeneous coating on the whole surface of thin plate 10, here the pattern of gimbal spring section is through with, add the uvioresistant sensitive agent then, expose then, make anti-responsive floor district carry out macromolecular polymerization reaction, next step is will not need the cladding portion etch to fall by nitric acid.
Adopt coating process to carry out coating, for example, floor 16 can form has high precision and easier, here rigid element 14 can be suitable for the head sliding support that reduces after the size, this just can have that the disk set size reduces and trend that capacity increases, therefore can realize undersized head slider support device.
Fig. 5 takes from the sectional view of Fig. 2 along line V-V.The floor 16 that has increased rigidity is formed on thin plate 10 surfaces, loads onto sliding shoe 13 here.Be formed with a thickness according to this embodiment floor 16 and cause thin pendulum spring part 11, floor 16 contact with recording medium and under this arrangement, prevent that sliding shoe from contacting with recording medium less than the thickness of sliding shoe 13.So just can realize a slim pendulum spring part 11.
If the coating that sliding shoe 13 forms is similar with floor 16, then can stop contacting of sliding shoe and recording medium, form sliding shoe 13 like this and can adopt similar manufacturing process with floor 16, carry out this technological process then from a side of thin plate, improved the head position degree of accuracy like this, manufacturing expense and labor hour also reduce.The formation technological process of head sliding shoe bracing or strutting arrangement will be illustrated with reference to figure 2.A kind of depart from material for example alumina (or name aluminium oxide) at first be plated in sliding shoe connector part 19 as bottoming, plate a kind of low magnetic coating such as Armco magnetic iron nickel alloy (or name permalloy) then.A kind of moulding work of given shape adopts the ion milling method to carry out then, and the formation of a conductor coils is to adopt a separation layer insertion, and a upper part magnetic coating, and this forms a magnetic core, and magnetic coating also inserts a separation layer on this.On by thickness direction, further form magnetic coating on this, but on this, between magnetic coating one appointed interval will be arranged, so just cause a magnetic gap that in the surface, is parallel to recording medium.Also have in addition and on one separation layer of top, plate a flash plating, plate this coating material for example silicon wimet or carbon, so just formed sliding shoe 13 to obtain resistance to abrasion.
Fig. 6 be gimbal spring section 12 and near perspective representation thereof according to the present invention, second embodiment of head slider bracing or strutting arrangement.The characteristics of this embodiment are that floor 16 will provide the rigid element 14 on vertical two limits of pendulum spring part 11, so its (referring to 16) is extended and is enclosed on the gimbal spring section 12 and is attached thereto together.Had such structure just can further increase the rigidity of rigid element 14, prevented the torsional deflection of pendulum spring part 11, these situations occur in floor separates when two limits, has therefore also just improved the twisting vibration performance.For simplicity, the part of wiring board has only been represented in this explanation, and its end portion figure then omits.
Fig. 7 is that gimbal spring section 12 and near skeleton view thereof but it are the 3rd embodiment according to head sliding shoe bracing or strutting arrangement of the present invention.The characteristics of this embodiment are that floor 16 is provided in a side of on the rigid element 14, equally also are located on the thin plate upper and lower surface.Fig. 8 is the sectional view of this enforcement, and this figure takes from Fig. 7 along profile line VIII-VIII.Adopt this structure just can reduce the thickness of pendulum spring part 11, and can improve conplane rigidity and in the rigidity of torsional direction.Can also reduce distortion, this distortion is the bimetallic effect that produces owing to temperature variation, and this occurs in floor 16 only when one side.
This head sliding shoe bracing or strutting arrangement is that an example of structure has been changeed 90 ° with expression gimbal spring section 12 direction as shown in Figure 2 according to present embodiment.According to this structure, these armed levers connect gimbal telescopic section 20 and pendulum spring part 11, be to be positioned at the longitudinal direction that horizontal direction passes head sliding shoe bracing or strutting arrangement, therefore just there is no need floor 16 to be set at these positions, above-mentioned these parts extend to the termination that far reaches gimbal spring section 12, thereby just can reduce the quality of head sliding shoe bracing or strutting arrangement, increase its free-running frequency and can carry out the high speed inspection operation.
Fig. 9 takes from the sectional view of Fig. 7 along line VIV-VIV.For example, both sides all have floor 16 and thin plate 10 on, lower surface is all formed by rolling sheet steel, and the distance piece 26 of a connector part is arranged on sliding shoe connector part 19 places of gimbal spring section 12.If this connector part distance piece 26 is to make with the coating material or the analog material of floor 16, this connector part distance piece 26 can form simultaneously with each floor so, when this sliding shoe 13 and gimbal telescopic section 20 are mutual one when overlaying on another, connector part distance piece 26 just can obtain to be offset rotatablely move some degree of freedom of face of sliding shoe 13 so.Also available other kind of the material of this connector part distance piece 26 is made.
Figure 10 represents that according to the fourth embodiment of the present invention this embodiment is the remodeling by example shown in Figure 8.Floor on the upper and lower surface links together in this embodiment.Its effect is that floor 16 can connect securely and the surface layer of floor coating can be simplified.
