Description

[Technical field]

[0001] The present invention relates to a base plate for a head suspension that holds a head that reads and writes information, a manufacturing method thereof, a head suspension, and a recording device. [Background technology]

[0002] As in Patent Document 1, in the head suspension, a load beam is attached to a mounting portion of a base plate, and a flexure, which is a wiring member, is placed on top of the load beam. A head is supported on the flexure. This support allows the head to be placed at the tip of the load beam and to face a disk, which is a recording medium, to read and write information.

[0003] In such a head suspension, the base plate has a recess in the thickness direction formed by thinning the mounting portion on the tip side of the base plate, and the base end of the load beam is attached by being inserted in the thickness direction into this recess.

[0004] This allows the load beam to be moved closer to the disk while maintaining the distance between the head and the disk, thereby reducing the distance between the carriage arms to which the load beam is attached.

[0005] As a result, it is possible to reduce the disk spacing, and it is possible to increase the recording capacity of the disk drive without increasing its size, or to reduce the size of the disk drive while maintaining its recording capacity.

[0006] However, in conventional head suspensions, a recess is formed in the base plate by thinning the base plate, which causes a problem that the rigidity of the base plate is significantly reduced in the recess. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2023-97516 A Summary of the Invention [Problem to be solved by the invention]

[0008] The problem to be solved is that when the base plate is made concave in order to mount the load beam, the rigidity of the base plate is reduced. [Means for solving the problem]

[0009] The present invention provides a base plate made of a plate material to which a load beam is attached, the base plate comprising: a base, a mounting portion for the load beam located in front of the base in a front-rear direction of the plate material, and steps defined on both sides in the plate thickness direction by displacing the mounting portion from the base so that one side in the plate thickness direction of the base is convex and the other side is concave for receiving the load beam, the steps on both sides being set to a dimension smaller than the plate thickness of the plate material and not overlapping with each other in the front-rear direction.

[0010] The present invention also provides a method for manufacturing the base plate, wherein the step is formed by half-punching the plate in a thickness direction.

[0015] The objective of suppressing a decrease in the rigidity of the base plate while making the base plate concave to attach the load beam is achieved by offsetting the base end portion of the base plate and the attachment portion in the plate thickness direction with a step that is smaller than the plate thickness.

[0016] The base plate 17 is made of a plate material and has a load beam 19 attached thereto. The base plate 17 has a base 17a, an attachment portion 17c for the load beam 19 located forward of the base 17a in the front-rear direction, and steps H1 and H2. The steps H1 and H2 are defined on both sides in the plate thickness direction by being offset from each other so that the attachment portion 17c is convex on one side in the plate thickness direction with respect to the base 17a and concave on the other side into which the load beam 19 is inserted. The steps H1 and H2 on both sides are set to a dimension smaller than the plate thickness of the plate material and are arranged so as not to overlap each other in the front-rear direction.

[0017] The steps H1 and H2 on both sides have step surfaces 17cc and 17cd that rise between the base 17a and the mounting portion 17c in the plate thickness direction, and the positions of the step surfaces 17cc and 17cd in the front-rear direction can be set appropriately. Therefore, the positions of the step surfaces 17cc and 17cd may be set at the same position in the front-rear direction or may be set to be shifted in the front-rear direction.

[0018] Moreover, the step surfaces 17cc and 17cd may be either perpendicular to the front-rear direction or inclined with respect to the front-rear direction.

[0019] The dimension of the step H2 on the other side in the plate thickness direction can be set appropriately, and may be set according to the dimension in the plate thickness direction of the mounting portion 19a of the load beam 19 relative to the mounting portion 17c.

[0020] In one embodiment, the mounting portion 17c may include a recess 17d and an actuator 17e. The recess 17d is recessed in the front-rear direction and penetrates the mounting portion 17c in the plate thickness direction. The actuator 17e is disposed in the recess 17d and operates the load beam 19 relative to the base portion 17a.

[0021] In the manufacturing method of the base plate 17, the steps H1 and H2 are formed by half-punching the plate material W in the plate thickness direction.

[0022] The attachment portion 17c may be formed by half-punching, which involves crushing the plate material W in the plate thickness direction.

[0023] The head suspension 13 using the base plate 17 includes a load beam 19, a wiring member 21, and a head 15. The load beam 19 is attached to the other side of the mounting portion 17c in the plate thickness direction while being inserted into a step H2 in the plate thickness direction. The wiring member 21 is disposed so as to overlap the load beam 19. The head 15 is supported by the load beam 19 via the wiring member 21.

[0024] A recording device 1 using a head suspension 13 includes a case 3, a recording medium 5, and a carriage arm 9a. The recording medium 5 is supported so as to be rotatable relative to the case 3. The carriage arm 9a supports the head suspension 13 via a base plate 17 so as to be drivable.

[0025] The mounting portion 17c of the base plate 17 may face the tip of the carriage arm 9a in the front-rear direction. EXAMPLES

[0026] [Recording device] FIG. 1 is a cross-sectional view that illustrates a part of a recording apparatus according to a first embodiment.

[0027] As shown in FIG. 1, the recording device 1 of this embodiment is a hard disk drive, and includes a case 3, a plurality of disks 5 which are recording media, a carriage 9, a positioning motor (voice coil motor) 11, and the like.

[0028] The disk 5 is supported by a spindle (not shown) so as to be rotatable relative to the case 3. The carriage 9 is supported by the case 3 so as to be rotatable via a pivot shaft 7, and is driven by a motor 11 for positioning.

[0029] The carriage 9 is provided with a plurality of carriage arms 9a. A head suspension 13 is drivably attached to each carriage arm 9a via a base plate 17. A head 15 is supported at the tip of each head suspension 13.

[0030] When the carriage 9 is rotated by the positioning motor 11, the head suspension 13 moves relative to the disk 5. This moves the head 15 to a desired track on the disk 5. When the disk 5 rotates at high speed, air flows in between the disk 5 and the head 15, forming an air bearing. In this state, the head 15 reads and writes data from and to the disk 5.

[0031] [Head suspension] FIG. 2 is a perspective view of a head suspension used in the recording apparatus of FIG.

[0032] The head suspension 13 includes a base plate 17 , a load beam 19 , and a flexure 21 .

[0033] The base plate 17 constitutes the base end of the head suspension 13, and has a boss portion 17b for crimping on a base portion 17a. The boss portion 17b is fixed to the carriage arm 9a of the carriage 9 shown in Fig. 1 by crimping. The base portion 17a is a mounting portion for the base plate 17, but the mounting method is not limited to crimping. The base plate 17 will be described in more detail below.

[0034] The load beam 19 is formed of, for example, a metal plate. The load beam 19 is attached to a base plate 17 and extends in the front-rear direction. The front-rear direction is the front-rear direction when the tip end side of the head suspension 13 is defined as the front and the base end side is defined as the rear.

[0035] A leg 19a is provided at the rear portion in the front-rear direction of the load beam 19. The leg 19a is formed, for example, in two parts and constitutes a hinge of the head suspension 13. The leg 19a of the load beam 19 is overlapped on the mounting portion 17c of the base plate 17 and fixed by spot welding or the like.

[0036] The flexure 21 has a main body portion 21a overlapping the load beam 19, and a tail portion 21b extending from the main body portion 21a to the rear of the base plate 17. A pad portion (not shown) is provided at the end of the tail portion 21b. A substrate (not shown) is connected to the pad portion. The head 15 is mounted on the main body portion 21a of the flexure 21 via a swingable gimbal portion.

[0037] When the head suspensions 13 are incorporated in the recording device 1, each disk 5 is located between the two head suspensions 13. When the recording device 1 is in operation, the heads 15 supported by the two head suspensions 13 face the upper and lower surfaces of the disk 5 while floating on air bearings.

[0038] [Base plate] Fig. 3 is an enlarged cross-sectional view showing a schematic view of a support portion for a carriage arm of the head suspension of Fig. 2. Fig. 4 is a perspective view showing a base plate of the head suspension of Fig. 3. Note that the plate thickness direction means a direction along the plate thickness of the plate material W constituting the base plate 17.

[0039] 3, the base plate 17 is made of, for example, a metal plate material W. The base plate 17 is formed in a substantially rectangular shape in a plan view and includes a base portion 17a and an attachment portion 17c located forward of the base portion 17a in the front-rear direction. The planar shape of the base plate 17 can be set arbitrarily.

[0040] The base portion 17a and the mounting portion 17c are formed by the rear and front portions of the base plate 17, which are bounded by step surfaces 17cc and 17cd, which will be described later in this embodiment. The base portion 17a and the mounting portion 17c have the same plate thickness in this embodiment. The plate thicknesses of the base portion 17a and the mounting portion 17c may be different.

[0041] The base portion 17a is a portion that is attached to the carriage arm 9a, and the attachment portion 17c is a portion that is attached to the load beam 19. However, it is also possible to configure only the portion where the leg portion 19a of the load beam 19 is attached as the attachment portion 17c.

[0042] A boss portion 17b is provided on one side surface 17aa of the base portion 17a in the thickness direction of the plate material W. This boss portion 17b is crimped into a crimping hole 9b of the carriage arm 9a, thereby attaching the base plate 17 to the carriage arm 9a.

[0043] The base plate 17 has steps H1 and H2 defined on both sides in the plate thickness direction. The steps H1 and H2 are defined by disposing the mounting portion 17c with respect to the base portion 17a so that the mounting portion 17c is convex on one side in the plate thickness direction and concave on the other side into which the load beam 19 is inserted.

[0044] The step H1 on one side in the plate thickness direction is a step between one side surface 17aa of the base 17a in the plate thickness direction and one side surface 17ca of the mounting portion 17c on the same side. These one side surfaces 17aa and 17ca are configured to be flat in the front-rear direction and the width direction, and define a uniform step H1.

[0045] The step H1 may be increased or decreased as the attachment portion 17c is separated from the base portion 17a. The width direction is the width direction of the head suspension 13 and the load beam 19, and is a direction perpendicular to the front-rear direction in a plan view.

[0046] The step H2 on the other side in the plate thickness direction is a step between the other side surface 17ab in the plate thickness direction of the base portion 17a and the other side surface 17cb in the plate thickness direction of the mounting portion 17c in the video. These other sides 17ab and 17cb are configured to be flat in the front-rear direction and the width direction, and define a uniform step H2. The step H2 may be increased or decreased as the mounting portion 17c is separated from the base portion 17a.

[0047] The steps H1 and H2 are set to have dimensions smaller than the thickness of the plate material W. In this embodiment, the dimensions of the steps H1 and H2 are set to be the same as the thickness (dimension in the thickness direction) of the leg 19a which is the mounting portion of the load beam 19 to the mounting portion 17c. However, the dimensions of the steps H1 and H2 can also be made larger or smaller than the thickness of the leg of the load beam 19.

[0048] The dimensions of the steps H1 and H2 on both sides are set to be the same, but can be different. The steps H1 and H2 are arranged so as not to overlap each other in the front-rear direction. These steps H1 and H2 have step surfaces 17cc and 17cd that rise up between the base portion 17a and the mounting portion 17c in the plate thickness direction, respectively.

[0049] The step surfaces 17cc and 17cd are flat surfaces along the thickness and width directions of the base plate 17. The step surfaces 17cc and 17cd may be formed into curved surfaces or the like. The step surfaces 17cc and 17cd extend between one side surface 17aa and one side surface 17ca and the other side surface 17ab and one side surface 17cb of the base portion 17a and the mounting portion 17c, respectively, in the thickness direction.

[0050] The rising of the step surfaces 17cc and 17cd means that the step surfaces 17cc and 17cd rise in the front-rear direction, and there are cases where the step surfaces 17cc and 17cd are perpendicular to the front-rear direction and cases where they are inclined. In this embodiment, the step surfaces 17cc and 17cd are arranged perpendicular to the front-rear direction. In this embodiment, these step surfaces 17cc and 17cd are set at the same position in the front-rear direction.

[0051] The step H1 on one side in the plate thickness direction causes the base 17a to be recessed relative to the mounting portion 17c. The base 17a is attached to the carriage arm 9a with the carriage arm 9a inserted into this step H1. In this state, the step surface 17cc faces the tip of the carriage arm 9a with a small or no gap in the front-rear direction.

[0052] That is, the mounting portion 17c faces the tip of the carriage arm 9a in the front-rear direction. Therefore, in this embodiment, the misalignment of the mounting portion 17c with respect to the base portion 17a in the plate thickness direction can be realized by utilizing the space in front of the carriage arm 9a.

[0053] The load beam 19 is inserted into the step H2 on the other side in the plate thickness direction. In this state, the load beam 19 is joined to the other side surface 17cb of the attachment portion 17c.

[0054] In the manufacturing method of the base plate 17, the steps H1 and H2 are formed in the thickness direction by half-punching a flat plate material W. This half-punching may be performed simultaneously with the formation of the boss portion 17b.

[0055] In the half-blanking process, the portions of the sheet material W that will become the base portion 17a and the mounting portion 17c are shifted relatively without changing the sheet thickness by a press or the like. It is also possible to change the sheet thickness of the portions that will become the base portion 17a and the mounting portion 17c.

[0056] The base plate 17 manufactured in this manner can be attached by inserting the leg 19a of the load beam 19 into the step H2 in the plate thickness direction, so that the projection of the load beam 19 and head suspension 13 facing each other across the disk 5 toward the disk 5 can be reduced while maintaining the distance between the head 15 and the disk 5. As a result, the distance between the carriage arms 9a to which the load beam 19 and head suspension 13 are attached can be reduced, and as a result, the distance between the disks 5 can be reduced. In other words, the number of disks 5 can be increased to increase the recording capacity of the recording device 1, or the recording device 1 can be made smaller while maintaining the recording capacity.

[0057] Moreover, in this embodiment, the thickness of the mounting portion 17c of the base plate 17 to which the load beam 19 is attached is prevented from becoming thin or is maintained without becoming thin, so that the rigidity of the portion supporting the load beam 19 can be ensured.

[0058] This allows the head suspension 13 to operate as designed, ensuring stability of operation. As a result, contact between the head 5 and the disk 5 is suppressed, and the recording capacity of the recording device 1 can be increased or the size can be reduced more reliably.

[0059] Furthermore, by fitting the leg 19a of the load beam 19 into the step H2, the load beam 19 can be brought closer to the carriage 9 in the front-rear direction, thereby improving the reliability of the pivoting operation of the head suspension 13.

[0060] [Variations] The following describes a modified example of the embodiment 1. Since the basic configuration of the modified example is common to the embodiment 1, only the differences will be described and a duplicated description will be omitted.

[0061] 5(A) and (B) relate to variant 1 of the base plate in FIG. 4, where FIG. 5(A) is an enlarged cross-sectional view that generally shows the support portion of the head suspension for the carriage arm, and FIG. 5(B) is an enlarged cross-sectional view that generally shows the state of the base plate shown in FIG. 5(A) before half-punching and after crushing.

[0062] 5A, the base plate 17 of the first modification has different thickness dimensions of the steps H1 and H2. In this modification, the thickness of the attachment portion 17c is smaller than the thickness of the plate material W constituting the base plate 17.

[0063] That is, the mounting portion 17c is formed by half-punching accompanied by crushing in the thickness direction of the plate material W. Specifically, as shown in Fig. 5(B), the other side surface 17cb of the mounting portion 17c is crushed so as to be disposed within the thickness of the plate material W, and then half-punching is performed to shift the base portion 17a and the mounting portion 17c in the thickness direction. The order of crushing and half-punching is arbitrary, and crushing may be performed after half-punching.

[0064] It is to be noted that the crushing process may be performed not only on the mounting portion 17c but also on the base portion 17a. Also, contrary to the first modification, the crushing process may be performed only on the base portion 17c.

[0065] In addition to the same effects as those of the first embodiment, the first modification can improve the rigidity of the other side surface 17cb itself to which the load beam 19 is attached by crushing. Even if the first modification is performed, the amount of crushing is smaller than the plate thickness of the leg portion 19a of the load beam 19, so that the decrease in rigidity can be suppressed.

[0066] 6 and 7 are enlarged cross-sectional views each showing a schematic configuration of modified examples 2 and 3 of the base plate of FIG. 4, respectively.

[0067] In the second and third modified examples, the step surfaces 17cc and 17cd on both sides of the base plate 17 are arranged to be shifted in the front-rear direction of the base plate 17.

[0068] 6, the steps H1 and H2 on both sides are spaced apart in the front-rear direction, and a wall portion 23 having a dimension in the plate thickness direction equal to or greater than the plate thickness of the plate material W is formed between the step faces 17cc and 17cd in the front-rear direction. This wall portion 23 improves the rigidity for supporting the mounting portion 17ca.

[0069] 7, the steps H1 and H2 on both sides partially overlap in the plate thickness direction, which results in different fulcrums for bending on one side and the other side of the mounting portion 17c in the plate thickness direction, improving rigidity.

[0070] In addition, the second and third modifications have the same configuration as the first embodiment and can achieve the same effects as the first embodiment.

[0071] Figures 8 to 10 are enlarged cross-sectional views each showing a schematic diagram of modified examples 4 to 6 of the base plate shown in Figure 4. Note that Figure 8 shows the base plate as a support portion for the carriage arm of the head suspension.

[0072] In the fourth to sixth modified examples, the step faces 17cc and 17cd of the steps H1 and H2 on both sides of the base plate 17 are inclined in the plate thickness direction and the front-rear direction.

[0073] The basic shape of the fourth modified example in FIG. 8 corresponds to that of the first embodiment in FIG. 3, and the step faces 17cc and 17cd in FIG. 3 are inclined.

[0074] The basic shapes of the fifth and sixth modified examples shown in Figs. 9 and 10 correspond to the second and third modified examples shown in Figs. 6 and 7, respectively, and correspond to the inclined shapes of the step surfaces 17cc and 17cd shown in Figs.

[0075] The inclination of the step surfaces 17cc and 17cd can be achieved by setting the die for half-blanking or by crushing after half-blanking.

[0076] The same effects as those of the above-described embodiment can be achieved in the fourth to sixth modified examples. EXAMPLES

Fig. 13 is an enlarged cross-sectional view showing a schematic view of a support portion of the head suspension of Fig. 11 for a carriage arm. Fig. 14 is a perspective view of the base plate shown in Fig. 13. Since Example 2 has a basic configuration in common with Example 1, differences will be described, and components that are the same as or correspond to those of Example 1 will be described with the same reference numerals, and duplicated description will be omitted.

[0078] The head suspension 13 according to the second embodiment of FIGS. 11 and 12 is used in the recording apparatus 1 as shown in FIG.

[0079] The base plate 17 of the second embodiment in Fig. 13 and Fig. 14 has a recess 17d in the front-rear direction (width direction) in the mounting portion 17c. The recess 17d in this embodiment is provided on both sides in the width direction of the mounting portion 17c and opens to the outside in the width direction of the mounting portion 17c in a plan view. The recess 17d penetrates the mounting portion 17c in the plate thickness direction. A piezo element 17e is attached to the mounting portion 17c as an actuator that operates the load beam 19 relative to the base plate 17.

[0080] In the second embodiment, the same effects as those of the first embodiment can be achieved. Moreover, the first to sixth modifications of the first embodiment can also be applied to the second embodiment. [Explanation of symbols]
