TWI243365B - Magnetic hub assembly for data storage disk - Google Patents

Abstract

A hub assembly for a data storage disk comprises a hub member and a raised boss near a center axis of the hub member, the raised boss being surrounded by an annular bonding surface and being configured so as to protrude into a center hole of a data storage disk when the bonding surface is in contact with a surface of the disk. Two hub assemblies are disposed on opposite sides of the disk, the respective raised bosses of the hub assemblies protrude into a center hole of the disk, where they are bonded to each other to increase the overall bonding force between the hub assemblies and the disk. The hub assemblies and disk may be bonded together using a UV curable adhesive. The hub assembly may also include a metal hub plate that is used to magnetically clamp the disk/hub assembly to the spindle of a disk drive. In one embodiment, the metal hub plate has several tabs that are bent around the disk to attach the metal hub plate to the disk. The metal hub also has features, such as notches, that are used to register the metal plate correctly with a die that is used in the process of bending the metal tabs. The hub member may comprise a material that transmits UV radiation, e.g., an optical grade plastic such as optical grade polycarbonate. In this embodiment, the hub member can act as a light pipe that transmits incident UV radiation to a UV curable adhesive at an interface between the hub assembly and a data storage disk or an interface with another hub assembly located on the opposite side of the disk. The UV curable adhesive may be cured by using the hub member as a light pipe to transmit the UV radiation to the adhesive.

The present invention generally relates to optical data storage media, especially compact light formula factor (smal 1-form-factor) of a drive means of data storage media. Many optical disk storage media have been developed for use in digital data stored in a variety of patterns, so that the media can be read from the medium for the design / write device or machine rapidly removed. Common current (typically read-only) examples include compact disks (CDs) and digital versatile disks (DVDs). Although these examples have been highly successful in specific applications, such as storing personal computer data, or storing music or other audio or video information, such as movies, these devices are designed for practical, historical, or other reasons. Applications that require smaller size optical storage media have proven to be less helpful. One such application includes various personal electronic devices (PEDs). Personal electronic devices generally have a size, shape, and weight that are appropriate and convenient to carry or wear on an individual. In general, such electronic devices need to be substantially sized to fit in a pocket

Examples of personal electronic devices include digital cameras, music duplication equipment such as small cassette players or MP3 players with headphones, cell phones, dictation devices, at least some types of small computers, known as personal digital assistants (PDAs) ), And the like. Due to, at least in part, the pandemic of personal electronic devices and the fact that specific personal electronic devices store (and / or use pre-stored) data, there are data storage systems that are at least compatible with personal computer size and weight restrictions and / Or media. Different types of data systems have been used or proposed for some or all personal electronic devices, but have proved inexhaustible for specific applications such as storage capacity, size, power consumption, data transmission, cost, and / or convenience ideal. For example, a technology for storing data in a digital camera is the use of an electronic flash card. However, the cost of storing a photo with a conventional flash card is a huge grasshopper for consumers. Because a photo requires more than 5M bytes of storage, based on the t: card's 4bergs, the storage cost of $ photos is approximately $ 20. In addition, these electronic cards or media are considered non-archival l ^ narChlVal (i.e., data that is broadcast without updates or similar operations is lost.). Therefore, consumers ... especially in the dagger examples of photographic film photographers point of view, to provide a comparison to shellfish, in

Therefore, it is useful to provide such a data recording system. This kind of data is fortunate to provide a removable medium. The removable medium is preferably a two-type, with a south transmission rate, low power consumption, and large power consumption.

The characteristics of the information content portion can generally be described as the portion of the optical medium from which information is read and / or written. The information content is often, but not necessarily, a composite layer containing two or more thin films, on which information is recorded (written) and / or information is obtained (read). Accordingly, the optical medium, or any of its 4's, can be classified into: read only, write-once, and rewriteable. Read-only optical media means that data or other information can only be read from the optical media under the control of consumers and their users. After the read-only optical media has been produced or manufactured, the user cannot write or record. The write-once optical medium or part means that the consumer or user can only record or write information once on the optical medium or part thereof. After the write-once optical medium or a part thereof has been recorded by the user thereon, the write-once optical body can no longer be written. That is, if a portion of the media has been written

• In a preferred embodiment, the optical media system a first surface media Cfifst ^ upface media). Although there may be more than one definition,

In one embodiment, the “first surface medium” means that the reading beam is emitted or irradiated on the information content portion of the first surface optical medium before being irradiated on the substrate of the first surface optical medium during the reading process. The "information content department ^ can be defined as an optical medium that stores or contains servo data, address data, and clock data" ^ user information, system data, and other information provided on optical media ' Those parts. The information content part is integrated on the substrate, as in the case of read-only media. The information content department can also be provided separately. In this case, the information content part can be “for example” an information layer or a writable medium. In an additional or another definition, the first surface optical medium may refer to an optical medium having a definite thickness. During the reading operation, the reading beam passes through less than 1 before being irradiated onto the information content portion. 00 microns

1,243,365 page 14 ^ ---- V. invention is described in (9) thickness. μ. In an embodiment, the “substrate” may be defined as an optical media layer having a thickness of at least 100. Preferably, the substrate can also be defined as an optical layer adjacent to a low-noise signal layer. Preferably, the substrate can also be defined as being thicker than any other optical media layer having a substantially homogeneous composition. In the case where the information layer is a composite layer or a multiple film layer, these definitions can be applied to a part of the composite layer or one or more films of the multiple information layer.

The first surface media provides several advantages over the second surface media. For example, with a first surface medium, the rays do not pass through a relatively thick substrate, so there is a relatively short light path, thus providing a shorter working distance compared to a second surface medium. Since there is a short working distance, a smaller objective lens diameter can be used for a predetermined number of apertures, resulting in smaller, lower-weight optical components, and a greater degree of miniaturization of the optical disc drive. Further, the first surface of the birefringent medium and the substrate thickness variation of the substrate is insensitive. The first surface medium is also less sensitive to substrate tilt.

Returning to the discussion of the structural characteristics of optical media, optical media have an outer diameter of about 40 mm or less (typically about 35 mm or less (such as 32 mm +/- 10%)), and about .6 mm the thickness (e.g., .6 mm +/- 15%). There is a data area on the optical media, a lead-out track, and a lead-in track. The lead and / or lead-out track includes a servo execution location and deficiencies and to prevent exceeding the optical scanning head. The extraction track is located at the extraction radius from the center of the optical medium. The lead-in orbit is a lead-in radius located from the center of the optical medium. The data area is between the lead-in radius and the lead-in radius. In one embodiment, the extraction radius no greater than about 6 · 5mm, introduced

Page 151243365 V. DESCRIPTION OF THE INVENTION (10) a radius of no more than about 1 6mm. In one embodiment, the lead-in radius is located outward relative to the lead-out radius (that is, the lead-out radius is closer to the center of the disc than the lead-in radius). The miniaturization of the media makes it easy for consumers to access, transfer and / or store. The media is small enough to be stored in a PED (Personal Electronic Device). In one embodiment, each media surface has a total capacity of about 250M bytes. The first surface optical medium has a data surface with a data density of about 2.6 Gbytes per square inch of information layer. A first surface of the optical storage media or disc having at least one (i.e., single-sided), and typically two (i.e., two-sided) information layer. Each layer includes information content mastered (ICM) data (which is typically read-only) and / or writeable areas (write once or rewriteable > input). As discussed in the previous application No. 60/140633, the ICM can be provided substantially on the optical storage medium all at once. This rewritable part can have a relatively long life and / or write once (non-rewritable) for the purpose of: for file-based storage, and / or the technology of forming the two regions can be substantially the same as the two regions Similarly, the difference between the two areas is essentially only related to whether or not the area has molding content (or other management information). For example, a contouring process can be used not only for managed content, but also for formatting, sector, focus, track, and / or rewriteable areas on a test disc. In one embodiment, the disc is available immediately after the forming or embossing process. This embodiment constitutes a monolithic disc structure, and the optical disc in the monolithic disc structure does not need to be coated and does not need to undergo a second treatment; more specifically, the monolithic disc can be regarded as ,at least

ICM or write data region may be located in the optical storage media of the same surface. When reaching about 250 Mbytes of data per optical media surface, the media at the beam wavelength, preferably, is located at about 4%. It is better to use thinner.

It is also provided to provide a repeat of the hub, and D and, A more basic basis is the vertical alignment of the angle. In the state of the sea, a reference plane can be obtained by using one of the surfaces of the disk M, W, and Y. It is defined to contrast media to ensure that the reference flat and the media system mistakenly strike plane located acceptable Xi known, people with ten heart birth te difference hub may be formed from a combination of, and / or comprise '- Species Made of magnetically attracted material to allow combination with a magnet that is incorporated in or incorporated into the optical disc drive to magnetically throw (or self-locate) the hub, and follow the media with a mandrel, and provide the torque of the optical disc drive. The magnetic field strength is between enough constraints machine slides on the disc media and providing power and torque can distort the media or media between difficulties force generated when the disc is removed from the machine. the hub member may engage (or provide structural support) to the cartridge housing ( (Not shown) to resist damage to the media caused by the side wall of the housing, such as the user, accidental crushing, or contact with the wall. The hub assembly can further include multiple features such as chamfered or Arc surface to facilitate positioning the center of the hub assembly on the mandrel associated with the disc player and guide and position the media during the loading of the media. Finally, the hub assembly can provide a cassette center opening (not shown) For example, it can avoid the contamination of the media data bearing part caused by external events, such as dust. In this embodiment, the 'hub assembly 4 1 0 0 includes one or more gaskets or connections. The connector 4180 is preferably made of metal, magnetic material, or plastic with a saturated metal material. The magnetic connector 41 8 0 has a hub assembly page 42124365, description of the invention (37) 〇〇 And the loading and disengagement of optical media with respect to the spindle shaft of the optical disc drive 2 does not produce harmful or excessive wear benefits. The magnetic connector Algo is attracted by the Hegu combination 4100 and optical disc drive magnets Mandrel. In this relationship, when the mandrel is inserted into the hub assembly 4 丨 00, a space is reserved between the magnet of the optical disc drive and the magnetic connector 418. Because of this space, it is important that the magnetic connector 4180 is designed to have sufficient strength to be suitable for connecting the mandrel and the hub combination through the magnetic connector 41 80. The magnetic connector 418〇 should be made of material and / or thickness that provides the desired strength of the magneto-optical drive magnet. Since the general hub assembly is 41 0 0, not the magnetic connector 41 8 〇, it is made of plastic. Specific design considerations or factors must be taken into consideration to avoid the breakage or cracking of the plastic part of the hub assembly 4100 that we don't want. Are preferred, the hub 4100 may include a combination of a first and a second hub member 422〇3,422〇1). The two hub parts are generally made of plastic. On the other hand, each magnetic washer 41 80 疋 metal. 4180 female washer having a magnetic 422〇 different coefficient of thermal expansion of each of the hub member. If a large part, or at least some parts, of the magnetic washer is restricted relative to the plastic valley combination 4200, the magnetic washer W80 that may generate stress may cause the plastic hub assembly 42 or the optical medium to crack, distort or damage . According to an embodiment, any relative expansion or contraction between any plastic hub member 4200 and the magnetic washer 418〇 will not generate an undesired compression force on the plastic hub member 4220 by the metal washer 4 丨 80. The tabs 426〇a-4 2 6 0 d include their placement, which can accommodate any two of these two parts to expand and contract with each other. In addition, any contact with the portion of region-based hub 422〇 or contact area or link the tabs 4260a-d formed of the gasket 418〇 little unaffected

Other areas or portions 1,243,365 ------ V. invention is described in (38) thereof in contact with or thermal coupling of the extension limit. Therefore, the effect of the different coefficients is small, if any. For the two hub members 4220a, b, each hub member is respectively connected to its washer 41 ', b. This independent attachment can avoid misalignment that is created when the centers of the first joint and the second joint between the hub and the second joint are not perfectly aligned. Because of & when —the comparison piece and the 塾 塾 circle, ° a are connected to the other side of the optical medium, they can be returned to the eleventh to sixteenth figures, respectively, which provide a further description of this embodiment . The hub assembly 4100 is adhered to the media or disc 4140 by an adhesive or molding (not shown). 41〇〇 hub combination of the first and second hub member 422〇a a ^ ⑽ are joined to the opposite surface 4140 of the disc. Central aperture disc surface substantially without any portion of the hub member 41 00 is. The hub assembly 4100 includes a hub assembly 4220a, b (which generally has the same chemical composition as the medium or the surface of the medium) provided in the radial direction or located in the magnetic coil or connector 4180a, 4180b. Each magnetic connector 4 1 8 0 a 'b can itself be a magnet (in this case, a magnetically attracted material hopper will be distributed in the ring channel of the optical disc drive) or a material that can be attracted by a magnet, such as Mild steel. Each connector 418〇a, 418〇b includes a plurality of outwardly extending tabs 4260a-d, a central hole 4300 for receiving the disc drive spindle t (not shown) 'and one or more adhesives Agent injection port 4340a, b. Each valley piece 4220 includes a plurality of slots 4380ad to receive the protruding tabs 4260a-d, one or more adhesive injection ports 4220a-d, and a channel 4460 for different injection ports. Connected to provide a path for adhesive injection, and bonded the part to the disc, and a central hole 4500. As in the previous implementation, page 44, 1243365 V. Description of the invention (39) For example, the hub member includes a chamfered or rounded surface 48 〇 around the hub member to facilitate the disc player (not shown) Placement of tablets. The connector 4180 is received by a serrated or concave surface of the hub member, which is defined by raised side walls 4540a-d having the same shape as the peripheral edge of the connector 4 180 (except for the tabs). Together, the side walls 4540a_d and the slots 4380a-d facilitate the alignment (or self-positioning) of the connector 4180 relative to the hub.

After the magnetic connector is aligned with the hub (such as the alignment of the tab with the corresponding slot), the various tabs 4260a-d are bent or rolled into the slot using a bending tool to form a line suitable for the tab and the slot. Line or interface. The space " s " (generally ranging from about 0. 01 to about 0. 10 mm) is located between the free end of each tab and the adjacent surface of the piece to prevent heat from the hub during bending. Disturbance to the drop. In order to avoid the contact of the tabs with the surface of the disc 414o, damage to the disc, and / or interference with the combination of the hub assembly and the disc, the outer surface 4600 of each tab 4260a-d is separated from the disc 4140. . The gap between the side edges 4700a-h of the tabs 4260a-d and the adjacent side walls of the grooves 4380a-d must be as small as possible or the sliding of the magnetic connector with respect to the hub 41 8o should be minimized. In one embodiment, the width of each of the tabs is about 丨 mi, and the interference is suitable to generate sufficient stress even at high temperature, so no material breakage occurs.

The hub and the magnetic connector attached to it can be aligned with the data channel, the perimeter, or the center hole of the media, and then adhered to the surface of the media. In an embodiment, the hub member 418 may include four adhesive injection ports placed along a line of a quarter circle of the hub member, so no matter how the magnetic connector is aligned with the hub member

As I will understand, the longitudinal center axis of the hole 5240 is actually aligned or coaxial with the center axis of the disc. In one embodiment, the surface 5160 the slope of Θ ranges from about 20 to about 7〇., and the slope α of the surface 52〇〇 from about 70 to about 20. the radius of the aperture .. typically from about 5240 to about 2.5 billion 5mm.

Page 48 1243365 Five 'invention 1 ^^ (43)' a '' '$ # In the embodiment of the twentieth figure, the first and second pieces 5 120 and 5080 are formed into the first piece 5120 having a surface 5 280 One of the adjacent surfaces of the disc is adjacent and separated from it by a distance " v, to prevent damage to the media caused by the first piece when the first piece is joined with the second piece. Offset distance " V = at least about 1.0 square 25 · 5mm larger than the square but, typically range from about to about billion-〇5 · 25mm. To provide a raised hub surface for magnetically removing the media, the first and first pieces each include a raised or flat annular area 5330a, b (Figure 20). The periphery of the area 533 0a, b has a radius "Rca", ranging from about 2 to about 5 mm. In the specific hub structure shown in the seventeenth to twentieth drawings, the second hub member 5080 has first and second Concentric ring 5360,5400. The junction of the two rings defines a step. The first and second concentric rings are received by the center hole of the disc. Therefore, the parts of the car are distributed in the center hole of the disc. The first member 5480 of the central bore telescopically receiving the first common center ring 536 billion. The size of the center hole and the first ring are essentially the same (for example, the largest difference in size will not be greater than about 3mm) to allow the first and second pieces to be used together by the power surname. The radius of the second ring typically range from just a radius of about two h5 to about Shang force from the first ring of about 5360! To about 4mm. As described, the step 5440 rises on the surface 5320 of the medium 50 0 0. The step height "Hs" is larger than the thickness of the media "τ", and generally ranges from about 25 to about 0.5 mm. The first degree of homogeneity above the second ring is generally no more than that of the first piece The height (depth) of the central hole is large. The twentieth figure shows the low profile of the hub assembly, and the low profile of the hub is small.

This ratio exceeds 1, because σ ~ Jiong group of the general exceed the thickness of the hub of the media. this ratio generally is at least about at least 2 (e.g., about 3), but typically does not exceed 5. another embodiment of FIG. ::: first embodiment, a disc is provided and registration The interface, which includes-a mandrel 600000 of the optical disk drive 6400, a heart, a pumping 60,000 and a 丄 Π? Are received in the _, the ring_circles the mandrel 6000 and is channel separation 6〇〇〇 mandrel 6240, and a magnet "μ distributed in a ring channel 6240 to maintain the positioning of media 63 2〇 (medium or magnetically removed) both rotating media before and during the optical disc drive. As it will be appreciated by I, the mandrel, the ring, the ring channel, and a magnet system and the rotary motor (not shown) related. The hub 6160 may be a plastic adhesive metal, the filler metal, or other material having magnetic attraction, the magnet being magnetically attracted 628〇. Magnet 6280 may be a dilute or thorium want of sufficient strength of the magnet. The reference or reference plane 6360 of the optical disc drive is defined by the surface 6400 of the circular ring 6200. By contacting the surface 6440 of the medium, the circular ring 6400 ensures that the surface 6440 of the medium 6 230 is vertically aligned with the reference surface 6360. The ring 6200 is inside. Page 50 1243365 V. Description of the invention (45) The bow of the surface 6440 contacting the surface of the medium 6320 allows the optical head to read the information on the extracted track. The outer peripheral surface of the ring contacts the media at a radius distance not greater than about 5.5 mm from the center of the media. The surface of the mandrel 60 00 60 80 and / or the inner surface of the ring 62〇〇 648〇 with respect to the central hub of the central bore 6160 to 6120 of media 6440 of mandrel surface is formed rounded or chamfered to facilitate setting 600,000. The slope of surface 648 (relative to a plane parallel to plane 6360) preferably ranges from about 20. To about 70. The slope of the surface 6080 is preferably from about 20%. To about 70. . An important consideration in actually reducing the type factor of an optical disc drive is to actually reduce the distance the media is raised above the mandrel during insertion or removal. Laizhao Figure 22, the distance between the mandrel 6000 inserted into the central hole 6120 of the hub 6160 is quite small. In one embodiment, the insertion distance " dagger " measured from the surface 6210 of the hub 6160 to the highest point of the surface 6080 of the mandrel ranges from about 0i to about 2.5mm. In other words, the insertion distance " Di " 'in the present embodiment, the hub-based total height 6160 of " 11 / is at least about 10%, not more than 5〇%. As shown in FIG twenty-second, more important is the distance between the surface of the circular ring surface 64〇〇 62〇〇 616〇 of the hub 6210 " Dc " (disk operating surface which is located on the hub the same height) to maintain as low as possible to provide low-height CD-ROM drive. On the seventeenth and eighteenth and 21 of the embodiment represented in FIG another embodiment, the present embodiment provides the majority of type (iv) a useful method for the optical and non-optical storage medium, wherein the medium 5000-based heat-shrinkable mounting (Shrink fit) s close the lower member 5040 of the hub 5080. During the formation of the media, such as molding or similar embossing procedures, the media 500 may be at a temperature just below the glass transition temperature. Based on a set of process parameters exist

1243365 V. Description of the invention (46) The difference (△ T) between the temperature of the hub assembly and the room temperature (peripheral temperature), ranging from about 50 ° C-100 ° C. Immediately after forming (such as removing the media from the injection mold), the lower hub part 50 8 0 of the hub assembly 5040 is generally at a lower temperature than the media 5 0 0 (especially when the hub part is substantially When the composition of the media is the same), it is inserted into the center hole of the media 5000. Due to thermal extension, the size of the central hole is larger than that of the central hole after it has been cooled. After cooling media, pore size shrinkage 5〇4〇 sidewall to the second ring member than the second stationary contacts of 5〇8〇. After the media 5 00 has cooled, the first 5120 of the hub assembly 5040 is combined with the second 5080, as discussed above. In one embodiment, the media 500 has a different composition from the hub combination. The rate of thermal expansion / contraction of the media is higher than that of the hub combination. In particular, the median expansion coefficient ranges from about i to about 3 e5, and the thermal expansion coefficient of the hub combination 5 080 ranges from about 1 to about 4 e6. According to the twenty-first figure of the second, the inner edge of the hole 5740 and the second hub piece 5800 are shown in the table. The space between 5780 determines that the medium is cooled before being loaded with the medium and / or broken . I want to keep the gap large enough to avoid too high media pre-loading and sexuality. Low storage / operating temperature and small enough to prevent the media line; surface) memory operations are run: the temperature has become loose lines between the hub and the media majority decision ^ ^ correct application of the foot. The linear relationship between

The temperature of the weight is determined by the relative proportion of the predetermined medium θ and the thermal expansion / contraction of several pieces: the gap, and the media can be cooled before the central hole]. The component is being inserted. The 敎 combination is usually in the surrounding temperature or; it is held in the surrounding temperature. The and the blade are in the middle, so when the two components are combined together

1243365________ V. Description of the invention (47) A '---- It is lower in temperature than the media. This method provides a hub having a high concentricity with respect to the media track. Π-is generally made of rotation and therefore has a high degree of concentricity. Medium heat receiving member co-administered executors media center than the member. Reduce the possibility of mounting a heat-shrinkable radius or more media loose vertical alignment. Another embodiment of the hub assembly is described in Figures 23 to 27. The medium 40 has a convex circular extension 608abcd formed on each side 61 20a, b of the medium "a to receive and position a corresponding magnetic attraction connection plate 6 160a, b, and assist the medium 604. 〇's center positioning. Extensions 680a, b, c, and d are distributed around the center of the media 604. They are better. Each pair of extensions 680, 0a, b, c, and d can be Center points were different relative, rather than the same point, the distribution as shown in FIG twenty fifth, 6〇a plate 61, b has a hole 6240 for 6〇8〇a by circular extension, 1) receiving And radially position the center of each side of the media. In one embodiment, the extensions are formed in the media 'such as during injection molding, or other kinds of embossment. As I will understand,' the extensions can be It is selectively arranged on the outer side of the plates, and the center of the plates is positioned with the center hole of the media. Figures 28 to 30 show another embodiment of the snap-fit mounting hub assembly. Yu Gu 70 In 0 0, a plurality of pointers 7 040a-d formed in the media substrate protrude outward from each side of the media 70 0. Each pointer pack The chamfered protruding blades 7120a-d protrude radially outward from the outer walls of the pointers 7160a-d. These pointers are grouped into pairs 7040a, c and 7 040b, d, so each pair of pointers has a position on the same side of the media. Blades 71 20a, c and b, d. Magnetic suction washers are interfered or snapped onto the respective chamfers mounted on each side of the disc

Thus on page 53, the thickness of the ring is generally not more than Sook, the blade knife and is typically about 71 9〇〇, ~ ",-eight children about a outfitting X Xing 37 within the substrate height on the surface of the adjacent medium 7080 sidewall "hf" phase angle ^ ^ phase of 72〇〇ad (7200B not shown) into the media in 7〇8〇. $ 1 protrudes outside, and as is the case the pointer is shown molded into the substrate surface of 4M ^ 724〇a_d (724〇b not shown) facilitate the mandrel (not dimethyl) with a central aperture of a media 7280 Of alignment. A hole 723〇a_d is provided between the wall and 716Ga_d and the media to allow the molding mold (not shown; the media is removed after the formation. The pointer 704〇a_d and the adjacent pointer 4〇ad (which has a location in the media the opposite face of the knife) and is offset by about 9〇 ^ o ^ heart to a needle (having edges on the same side of the medium) temporarily offset by about real / ". \ allow removal of the mold of the present embodiment. Wu γ mounted on penetration of engagement or an interference elimination adhesive connection to the media required for the gasket comprises: Ten: FIG showing another embodiment of a hub of a hub combination compositions 9〇〇〇 months packets called first. The first and second magnetic connectors or washers 9040 and 9080, sets of 120, which generally have the same Qlni as the disc or the substrate of the disc. Γ A magnet 9040 and 980 includes an inner ring step 9160 and a皮 se * 二 二 p ί is used to receive the desiccant 1 and the other is used to join the core ladder in the sleeve 9120. The outer surface of the magnetic connector is to be joined with the optical disc spindle 9320. Because

= In ^ tube 912〇, the media 9400 is tightly joined to the sleeve 9i20J. The effect is as achieved by interference or wire-to-wire installation. Therefore, the magnetic connector must have enough area adjacent to the magnet 9500 to produce an efficient magnetic closure. Therefore, each magnetic 1 040,9 080 includes a flat annular area 9 54〇 and 9〇80 near the disc 1243365.

In and adjacent to the magnet 9500. The width " w " of the flat regions 9540 and 9580 is generally from about 0.5 to about 5 mm. As I will understand, the combination of the hub combination 9 0 0 is made by first passing the cylindrical portion 9600 of the sleeve 9120 through the central hole of the magnetic connector 90 80, and secondly passing the cylindrical portion of the sleeve 9 Through the central hole of the medium 9400, the third step passes the cylindrical part of the sleeve through the central hole of the magnetic connector 9 ^ 40, and finally applies an adhesive to the disc 9040 and the ring channel 9 7 defined by the sleeve. In 0, the type of the adhesive is preferably any suitable adhesive having a viscosity requiring ultraviolet treatment. The hub assembly does not require a fixing device, substantially removing possible adhesive on the disc throwing surface, allowing the magnetic gasket " to float, (for example, having freedom of movement in the side or side-to-side direction, because each disc is and the inner edge of 4〇 9〇8〇 980 0a, b adjacent to the sleeve surface 9120 of the separation), and only needs to be applied in the adhesive compositions of the hub side. Further, the twenty-second to thirty-seventh drawings show another embodiment of the present invention, which includes a combination 9900 (thirty-third image) and a metal hub plate 9910 (thirty-second image). The thirty-fifth figure shows a hub assembly 9999, which includes a hub member 9900 and a metal hub plate 9 9 1 0. The hub member 9 9 00 may be made of, for example, polymer carbonate, opt 1 cal grade (0 · G ·) plastic. A hub member comprising _ over the side wall 9900 or 9920 block, which defines a circular recessed area 9918 to the metal hub plate 9910 for mounting on the premises. An inclined region 9 9 2 2 is bounded radially outward from the frame 9920, which ends at the edge of the hub 9 9 0 0. In one embodiment, the diameter of the circular recessed region 9918 is 608 mm], and the outer diameter of the hub member 9900 is 770 mm. The central hole 9926 may be, for example, 1.6 mm in diameter and formed with respect to the central axis of the hub member 9900. Four notches 9924 surround the circle of the hub 9900

1243365

As shown in the thirty-fifth figure, the lower side of the hub member 9900 has four recessed areas 9925 from the inner radial direction. The notch 9924 can be tapered so that the outer edge of the hub 9990 can be slightly wider than the area adjacent to the 9925.

Than 9999 combinations of functions somewhat similar to the vehicle shown in a twelfth of the sixteen and FIG combination 41〇〇. For example, the presence of the metal plate 9910 allows the hub 9999 to be magnetically clamped to the spindle of the optical disc drive. However, there are some big differences between the hub combination 4100 and the hub combination 9910. Neither the hub 9900 nor the metal hub plate 9910 contains an adhesive injection port. UV-curable adhesive has been found to be particularly effective adhesion agent, and UV-curable adhesive can not be too close so that the injection for the inbound =. The UV-curable adhesive is preferably applied to the component and / or the disc before combining the two parts in order to position the hub relative to the shell area. Secondly, the metal hub plate 9910 contains a notch 9916, allowing it to be correctly instructed relative to the die used to bend the tabs 99 12 into the notch 9924, as described in the [M —872 9US] reference application above . In addition, the hub plate 9 90 0 includes a convex column 9932 for merging with another = hub-like convex column at the interface 99 42 as shown in the thirty-sixth figure. When the two unions 999 9, 9998 are set in one When the data is stored on a disc. Zhuyin Tiancui 〆 29932 has a diameter slightly smaller than the inner diameter of the central hole of the disc 9940 <, ^ ′ 疋 \ A hub piece is independently placed on the data area on the side of the disc. Allow multiple hubs to combine with each other to create a hub-to-disc combination. I have found that the strength of the unit between two polymers is the strength per unit area is 4 times the binding force between the hub piece and the metal film on the general piece (shown in Figure 36). '= Sheet surface 9 944). On the whole, the “bonding strength” of the hub pieces shown in the thirty-sixth figure is about 丨 0 times greater than that of the non-hub pieces. ,,,
