Description of the Invention (I) Background The present invention relates to computer data storage systems, such as magnetic disk drives. More particularly, the present invention relates to a drive suspension used in a drive. .. Microprocessors and supporting computer technology increase rapidly in speed and computing power, as costs and sizes decrease. These factors have led to the widespread use of microprocessors in electronic products, such as handheld computers, digital cameras, mobile phones, and the like. In fact, all these devices have become computers with special device-specific properties. D For new types of computer products, different flexibility can be used. Gained from the ability to change data files and store computer software. Different dedicated storage devices have been used in computer products. For example, a handheld computer has used an integrated circuit memory card 0 as the main data storage medium. Memory cards include memory storage components, such as static random access memory (SRAM), or programmable and non-volatile memory, such as "flash" memory. Billion cards are typically the size of a conventional credit card and are used in portable computers to replace hard drives and floppy drives. Furthermore, the memory card increases the advantages of the size, weight, and battery life attributes of the portable computer and increases the portability of the storage medium. However, due to the limited memory density available on each memory card and the high cost of special memory chips, the use of memory cards in handheld computers creates limitations encountered in non-portable computers, which typically use more power and Heavier hard disk drives and floppy disk drives are used as the main storage medium " The use of disk drives in these portable computer devices gives a distinct design to components made in the disk drive. For example, the drive is small and durable. The drive design of these precision portable computers is continuously required. __4________ This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (read the precautions on the back before filling this page).

Description of the invention (,) Reduce the size of the components in the disk drive and reduce the size in the z direction of the disk drive. performance. In order to make these drive devices more mobile, modern designs require that the drive must be heavy and light, and must not overcome severe mechanical shock and vibration. These design constraints require modern component designs that have not been encountered in previous drive subsystems. Abstract The present invention is directed to suspension devices used in drives, which meet the requirements of providing light weight and precision design, which can withstand severe Mechanical shock and vibration. The suspension device having the present invention includes a load beam to which a balance frame is connected and the read / write head is connected to the balance frame. The load ring has a substantially flat body, a base end, and a bottom at the base end. The actuating arm for fixing the suspension device to the disk drive, the end, the bottom, the top, the sides, and the recess are printed on the load beam. The top of the end is along the longitudinal axis and is placed near the end such as the recess so that a convex surface is at the bottom of the load beam. The recess includes a main body portion that is connected to or integrated with the load beam. An elastic hinge portion floats about the convex surface of the recess on the load beam, and at least one elastic bridge portion connects the main portion to the hinge portion of the recess. The read / write head is connected to the hinge portion of the recess so that the read / write head can be adjusted to the surface of the medium. The elastic hinge portion of the recess and the read / write head are placed near the recess of the load beam. The load beam further includes one or more extended track portions. This extended track portion is used to tension the load beam and support the end of the load beam. Preferably these extended track portions are turned and rolled relatively perpendicular to the plane of the surface of the load beam body and offset from the surface of the medium within the drive.

The restraining device further includes a load beam having an extension portion mounted at the end. The extension is turned downwardly perpendicular to the surface defined by the load beam whose load beam faces the surface of the medium in the disk drive. The bend is made towards the medium for storage in the z-direction and provides a smaller and more durable disk drive design by adding a feature to overcome severe mechanical shocks and vibrations while requiring no additional height. The downwardly extending portion has an opening forming an outlet of the load beam. The load beam exit acts as a restraining member at the end of the load beam. When the load beam exit has a different shape, it is preferably rectangular. The gimbal has an extended tab portion that extends from the end to the end of the hinged portion of the gimbal, substantially in the same plane as the gimbal. The tab portion is used to engage the load beam exit. The load beam exit acts as a restricting member to restrict both vertical and horizontal movements of the tab portion of the gimbal. The gap between the curved tab portion and the load beam exit is used to limit the movement of the curved tab portion of the gimbal during an impact event, such as during head loading or unloading. According to another aspect of the present invention, the load beam has a substantially flat body having at least one receiving space. The gimbal has a main body part connected or integrated with the load beam. The gimbal also has a hinged part to connect and support a read / write head. The gimbal has at least one flexure bridge portion that connects the main body portion to the hinge portion. Preferably, the short bridge part of the balance frame _6_ This paper is again applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) " Α7 Β7 Printed by the Consumer Cooperative of the Central Government Bureau of the Ministry of Economic Affairs The number of notes (4 ·) is relative to the number of accommodating spaces in the load beam body. The flexure bridge portion of the balance frame is placed close to the receiving space of the load beam ', for example, when the flexure portion is bent, a gap is provided between the flexure bridge portion of the balance frame and the load space's accommodation space. A flexure bridge with two receiving spaces on the main body of the load beam and two gimbals is preferred. The accommodating space will allow full free movement of the deflected bridge portion and the fixed head will therefore reduce head movement relative to the medium.

The extended track portion 32 may Formed in one piece or manufactured individually and then connected to the load beam 44. Preferably, the extension track portion 32 includes two extension track portions 32 that are placed along the sides 34 of the load beam 44. Preferably, these extension tracks The portion 32 is turned or rolled relatively perpendicular to the surface of the load beam body 45 and in a direction away from the surface of the medium 14 in the disk drive. Alternatively, the extension track portion 32 may be rolled so that the portion is originally under the plane of the load beam body 45 and then rolled up to deviate from the direction of the surface of the medium 14 in the disk drive so that additional weight is not required of. The extension rail 32 may also be turned, folded, or rolled in a direction toward the surface of the medium M in the disk drive. Preferably, these extension track portions 32 also extend substantially over the entire length of the load beam 44 and over at least a portion of the balance frame 39 and the head device 54. According to another aspect of the invention, the load beam 44 further has an extension 33 at the end 49. Preferably, the extension portion 33 is turned downwardly and relatively perpendicularly to a plane defined by the surface of the load beam 44 to face the direction of the surface of the medium 14 in the disk drive 50. The downward steering system is oriented towards the medium 14 so that space is saved in the Z direction and additional drive height is not required. The downward turn is obvious because earlier disk drives revealed designs in which the components of the disk drive were turned away from the surface of the medium. It is normal for a drive to turn sharp edges away from the media so that the media is not damaged by touching any sharp edges. This feature becomes even more important, as designs for disk drives continue to demand smaller and more durable specifications, which can still overcome severe shocks and vibrations. 10 This paper size applies to China National Standards (CNS) Α4 specification (210X297 mm) --------- installation— (Please read the precautions on the back before filling this page) Central Bureau of Standards, Ministry of Economic Affairs Printed by Shelley Consumer Cooperative A7 B7 _ V. Description of the Invention (?) The drive manufacturer managed to keep the sharp metal edges away from the rotating disc (medium 14) due to severe damage and loss of related data, if the metal edge contacts the medium 14. The medium 14 is made by bending the extended portion 33 toward the medium 14 to guide the sharp metal edge of the load beam 44. Given this option, most designers and drive manufacturers will bend the gimbal 39 upward, place an exit slot, and extend the load beam 44 through the exit. In this way, the sharp metal edge is pointed away from the medium 14. Conversely, the downwardly turning extension 33 of the load beam 44 of the present invention is turned toward the medium 14 and has an opening to form a load beam exit 35. The downwardly turning extension 33 forms a plane which is not on the same plane or is not coplanar with the load beam 44. Preferably, the plane defined by the load beam exit 35 is substantially perpendicular to the plane defined by the load beam body 45. The load beam exit 35 can take different shapes, including but not limited to square, rectangular, circular, diamond, triangular, semi-circular, oval, and the like. Moreover, the load beam outlet 35 may be integrated with the main body 45 of the load beam 44 or the load beam outlet 35 may be formed separately and then connected to the load beam 44. The load beam exit 35 allows limited movement of the gimbal 39 and the read / write head 54 while acting as a limiting member at the end 49 of the load beam 44 at the same time. The restricting member restricts the movement of the end 39d of the gimbal relative to the end 49 of the load beam. The limiting feature of the extension 33 is to limit the extreme movement of the gimbal 39 and the head 54 during an impact event and thus prevent damage to these components. In addition to keeping the metal edge away from the medium 14, another feature of the present invention is the placement of the outlet 35 Under the balance frame 39. During vertical impact, balance ___11 This paper size applies to China National Standard (CNS) A4 (210X2 ^ 7 mm) ^ 11 ^ 1 n # nn m ^^^^ 1 ^^^^ 1 ^^^^ 1-, J, ¾-s (Please read the precautions on the back before filling out this page) 4 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 __B7 _______ 5. Description of the invention (q [) The 39 frame is bent, when the balance frame Resist the forces generated by the accelerated mass of the head 54. When the gimbal 39 is bent, the ring is effectively shortened in the planar direction. When the outlet 35 is placed on the balance frame 39, during the vertical impact, the balance frame 39 is shortened in the plane direction and the balance frame 39 is increased and the load beam 44 is extended: the connection of the portion passes through the outlet 35. (Because the load beam 44 is 2 to 3 times thicker than the balance frame 39, the load beam extension tab 37 has less bending than the balance frame 39 during an impact). In contrast, when the outlet 35 is placed on the load beam 44 during a vertical impact, the gimbal 39 is shortened and the gimbal extension tab 37 is reduced in connection with the load beam 44. For the impact level required by the preferred device 50, the gimbal extensions 37 can be shortened enough to completely release the load beam outlet, making the device 50 ineffective, unless careful selection (optimization) of the components is considered. Correcting this plane shortens the gimbal, and the extension tab 37 needs to be as wide and long as possible. However, the length of the tab 37 is limited by the small-width form of the device 50, and the width of the tab 37 is limited by the length of the gap between the tab 37 and the exit opening 35. To allow the head 54 to move (forward and roll), the gimbal extension tab 37 does not touch the inside of the load beam exit 35 during operation. Conversely, if the outlet 35 is formed on the balance frame 39, the load beam tab does not contact the balance frame outlet as conventionally known. However, due to the Z-height limitation of the device 50 in the Form II style, the outlet 35 must be replaced. It is formed on the load beam 44 and then curls toward the medium 14 »Because the distance from the load beam 44 to the exit 35 is very small, the paper size of the paper 12 applies to the Chinese national standard {CNS) 4 Zhuge (210X297 mm ) -----I n ^ vm ^ l ^^^^ 1 ^^^^ 1 .l ^ v- nlf ^ 1—Jd (Please read the notes on the back before filling out this page} 28 28 Central Ministry of Economic Affairs Printed by the Zhuhai Bureau Shellfish Consumer Cooperative A7 B7 V. Description of the Invention (fc?) The port 35 must be very small. Because the exit 35 must be very small, the extension tab 37 of the balance frame 39 must be very narrow so that the balance frame is extended The portion 37 does not contact the inside of the load beam outlet 35 during operation. During the vertical impact (Z axis), the narrowness of the gimbal 39 increases in the direction of shortening in the plane direction. This is derived from the present invention. If there is a Z height space, the The obvious solution to the problem is to bend the exit 35 by the gimbal 39 upwards, as in the conventional method. By the shape of the balancer plate 37 and the load beam exit 35, the opening size of the magnetic disk drive 50 meets the requirements of the operation and the Philippines operation. For use in a roughly removable magnetic disk drive 50 β For example In a preferred embodiment, the requirement of the magnetic disk drive 50 is that the actuator 56 (head, load beam, gimbal, loop device) does not contact the medium 14 ′ when the medium does not rotate. This is called a stopped state. Another requirement is that the head 54 is not in contact at any time. Therefore, 'the head 54 needs to be separated by some components, called the load ramp 52, when the head leaves the edge of the medium I4. The preferred magnetic disk by the load ramp 52 The separation of the head 54 of the machine 50 is about. The total Z height between the chassis 57 and the top cover 13 is about 2.5mm. This leaves about 0.55mni between the top of the load slope 52 and the top cover I3, and the load Between the bottom of the bevel 52 and the chassis 57. The gap of the load beam 44 is about 0.15mm at the top and bottom. Therefore, there is insufficient space to place the exit 35 on the balance frame 39, and the problem condition of placing the exit 35 on the load beam 44 must be solved Extension tab 37 shape and out 35 Careful choice of opening size is indicated.

Preferably, the extension tab portion 37 extends in the same plane as the balance frame 39. The load beam outlet 35 functions as a restricting member to limit the movement of the tab portion 37 of the balance frame 39. The load beam exit 35 is planned to allow free movement of the read / write head 54 where the head is connected to a hinged portion 39c within a restricted range of motion. The range of this movement is based on the characteristics of the individual components of the special device and suspension device 48. Preferably, the vertical range of motion will be limited to prevent any plastic deformation of the gimbal 39 and prevent the opposing heads 54 from contacting each other, or prevent the heads 54 from contacting other components in the disk drive 50. The design of the load beam exit can be used to limit the movement of the head 54 in the horizontal direction due to excessive shock or vibration. In another aspect of the invention, the load beam 44 has a flat body with substantially at least one receiving space 30. In addition, the gimbal 39 is formed to have at least one elastic bridge portion 39a. The accommodation space 30 is shaped, for example, with sufficient clearance for the elastic bridge portion 39a of the balance frame 39 to enter the accommodation space 30 and is fixed or bent or twisted without touching the sides of the accommodation space 30 or the load beam 44. The receiving space 30 may include different shapes and in a preferred embodiment, the receiving space 30 has a rectangular shape. In addition, the receiving space 30 may include any specifications that provide a device for allowing the elastic bridge portion 39a to bend freely into the receiving space 30. For example, the receiving space 30 may include a groove or cavity formed in the load beam main body 45, or preferably the receiving space 30 may include an opening or a through hole formed in the load beam main body 45. The use of openings or through-holes as a specification of the accommodation space 30 provides a free bend of the elastic bridge portion 39a 1--mn ^ lm It kr K—. ^ 1 ^ 1 ^^^ 1 ^^^ 1- ·, J (Please Read the notes on the back before filling this page.)

Description of the invention (〇) When reducing the weight of the load beam 44 structure at the same time. As shown in Fig. 4, the load beam 44 preferably has two receiving spaces 30 in the form of rectangular openings. As shown in FIG. 4, two receiving spaces 30 are placed on a load beam 44 such that the longitudinal length of the load beam 44 is substantially parallel to the longitudinal length of the receiving space. The first accommodating space 30 is placed between the middle line of the load beam 44 and the side of the load beam 44 and the second accommodating space 30 is placed on the other side of the middle line of an area, the area is between the load Between the center line of the beam 44 and the other side 34 of the load beam 44. The two receiving spaces 30 are placed between the proximal end 46 of the load beam 44 and the recessed area. The balance frame 39 couples the head 54 to the load beam 44. As shown in Figs. 5 and 6, the gimbal 39 includes a main body portion 39e, at least one elastic bridge portion 39a, and a hinge portion 39c, and is placed at an end portion 39d at the end of the hinge portion 39c. The balance frame 39 may be coupled or integrally formed with the load beam 44. Preferably, the main body portion 39e is mechanically connected to the load beam 44. In the preferred embodiment, the body portion 39e is welded to the load beam 44 near the point 70 (see FIG. 5). The gimbal 39 also has a hinged portion 39c which connects and supports the read / write head 54. The hinge portion 39c is substantially freely inclined along the longitudinal axis of the load beam 44 and the portion floats with respect to the recess 31. The balance frame 39 is placed in the recess 31 so that the balance frame 39 is free to move and twisted to adjust the head 54 to the surface of the medium (not shown). Preferably, the balance frame 39 comprises a thin curved material, such as a thin flat metal. As shown in Figs. 5 and 6, at least one flexure bridge portion 39c connects the main body portion 39e to the hinge portion 39c of the balance frame 39.

Description of the invention (α) The curved portion 39a is placed close to the accommodation space 30 in the load beam 44. For example, when the hip curved portion 39a is bent, a gap is provided between the curved portion 39a and the receiving space. Preferably, there are two bridge portions 39a, which are placed close to the two receiving spaces 30 on the load beam 44, as shown in Figs. 4 and 6. The read / write head 54 is connected to the gimbal 39 so that the read / write head 54 can be adjusted to the surface of the medium. Preferably, the read / write head 54 is connected to the elastic hinge portion 39c of the balance frame 39 so that the head / balance frame device can pivot about the convex surface of the concave portion 31 of the load beam 44. In the preferred embodiment of the present invention, the suspension device 48 includes an opposite group of load beams 44, a balance frame 39 connected to each load beam 44, and a read / write head 54 connected to each balance frame 39. One read / write head 54 will contact the top of medium 14 and the other read / write head 54 will read / write to the bottom of medium I4. 4 to 6 show a preferred embodiment of the present invention. Due to the flexibility and weight reduction provided by the accommodating space 30, the extension track portion 32 can be extended over almost the entire length of the load beam 44, providing a more rigid and impact-resistant suspension device 48. Preferably, the extension rail portion 32 of the load beam 44 extends substantially over the entire length of the load beam 44 and over at least a portion of the balance frame 39 and the head device 54. The extension track is used to tighten the stomach-carrying beam 44 close to the recess 31, resulting in an increase in the use of natural non-planar bending vibration mode. The final tensioning tip also reduces any positioning errors due to the response of this mode. The extension track 32 helps to protect the head 54 from damage to the stomach during handling. According to a further aspect of the present invention, the head 54 can withstand the stomach and stomach 16 in FIG. 4 _______ This paper standard is generally Chinese National Standard (CNS) A4. 2! 〇χ297mm) (Please read the precautions on the reverse side before filling out this page) Binding · Order 4484 28 Printed by the Central Consumers' Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, A7 B7 5. Direction of the Invention (A) 61 Rotation motion. To provide sufficient elasticity, the accommodation space 30 provides an additional clearance for the bridge portion 39a to bend without contacting the load beam 44. The additional freedom provided by the head 54 is provided by the additional clearance provided by the receiving space 30 to adjust to the media surface (not shown) without the balance 39 or the head device 54 hitting the load beam 44. The number of the elastic bridge parts of the preferred gimbal 39 is relative to the number of the accommodation spaces 30. Preferably, the load beam 44 has two receiving spaces, which are located in the main body of the load beam 44. Therefore, in the previous embodiment, the two receiving spaces 30, the balance frame 39 will have two elastic bridge portions 39a, which connect the main body portion 39e to the hinge portion 39c of the balance frame 39. The two elastic portions 39a of the balance frame 39 are placed close to the receiving space 30 of the load beam 44. For example, when the elastic portion 39a is bent, the gap is provided between the elastic bridge portion 39 of the balance frame 39 and the receiving space 30 of the load beam 44. between. For example, when the flat flood ring 39 is rotated in the direction of the arrow 61 (see Fig. 4), one of the bridge portions 39a will rotate away from the load beam 44 and when the other bridge portion 39a rotates toward the load beam 44. Without the receiving space 30 of the load beam 44, the bridge portion 39 a turned toward the load beam 44 may possibly hit the load beam 44. Therefore, the movement and flexibility of the gimbal 39 will be restricted. The accommodating space 30 allows the flexed bridge portion 39 a and the fixed head 54, thereby reducing the movement of the head 54 with respect to the medium 14. The hinge portion 39c of the gimbal 39 is not attached to the load beam 44 and therefore moves freely. Because the end portion 39d at the end of the hinge portion 39c is free to move, excessive impact on the disk drive 50 along the vertical axis may cause the gimbal 39 to bend downward in the direction of the arrow 60 (see FIG. 4). Excessive bending of the balance frame 39 may cause plastic deformation of the balance frame 39, resulting in permanent damage.

Description of the invention () To prevent this poor result, a device is provided between the load beam 44 and the balance frame 39 to reduce the relative movement between the ends of the two structures. According to a preferred embodiment, the load beam 44 has an extension 33 placed at the end 49. It is preferred that the extension portion 33 is turned relatively perpendicularly to a plane defined by the load beam 44 in the direction of the disk drive 50 toward the surface of the medium. In contrast to the previous design, the bend is made towards the medium 14 so that additional drive heights are not needed. This feature saves height in the Z direction and becomes more important when the design requirements for these types of drives require smaller and more durable specifications for handheld and portable devices. The drive height is an important design specification to determine that the drive 50 of these devices is as fine and lightweight as possible and still withstands severe shocks and vibrations. The steering extension 33 has an opening which defines a load beam exit 35. The load beam exit 35 acts as a restricting member at the end 49 of the load beam 44. Preferably, the balance frame 39 has an extended tab portion 37 extending from an end portion 39d of the hinge portion 39c. The extension tab portion is used in conjunction with the load beam exit 35. Preferably, the extending tab portion 37 of the balance frame 39 projects through the load beam outlet 35 to limit the vertical movement of the balance frame 39. In addition, the exit form specifications of the load beam exit 35 also help to limit the horizontal or side movement of the balance frame 39 and the head device 54. The gap between the flexure tab portion 37 and the load beam exit 35 acts to limit movement of the flexure tab portion 37 of the gimbal 39 during an impact event, such as what happens during a head loading or unloading process. Therefore, the head 54 is attached to the flexure tab portion 39c, and the head hits any other element outside the allowable range of the head or load beam exit 35 of another relative suspension device.
