Description of the invention (丨) Background of the invention The present invention relates to a flexible magnetic disk provided inside a magnetic disk casing. Cartridge-based data storage system. More particularly, the present invention relates to a gasket for a magnetic disk casing, wherein the gasket is attached to the protective casing. Microprocessors and supporting computer technology increase rapidly in speed and computing power, while reducing cost and size. These factors have led to the widespread use of microprocessors in many electronic products, such as laptops, digital cameras, mobile phones and the like . All of these devices are effectively computers with special application characteristics. For these new kinds of computer products, 'the ability to exchange data files and store computer software' can be widely adapted. Many proprietary storage devices have been used in computer products. For example, portable computers have used integrated circuit memory cards (memory cards) as the main information storage medium. Memory cards include memory storage units, such as static random access memory (SRMO, or programmable and erasable non-volatile memory, such as "flash" memory. Each memory card is typically the same size and used as a conventional credit card In portable computers to replace hard disk drives and soft disk drives. In addition, memory cards enhance the advantages of the size, weight and battery life of portable computers, and increase the portability of storage media. However, because each The memory density that a memory card can reach is limited, and the special memory crystal is expensive, so using a memory card in a handheld computer to force it to encounter fewer restrictions on portable computers, which are typically Use hard disk drives and soft disk drives with high power consumption and heavy weight as their main CNS) Λ4 秘-(21 () 、 297 公 、) " (+ 衣 ------ ::: r ------ line (please hear first note please note -1; sub-item then 4.:!?

Other computer products mentioned above , Such as digital cameras, have already adopted small image disks as Its storage medium, for example, U.S. Patent Publication No. 4,553,175, published on U.S. 12, 1985, Baumeister discloses a digital camera configured to store data on a magnetic disk. In this case, a signal processing The receiver receives a signal representing a picture from a camera sensor. These signals store data on a disk for subsequent processing. Unfortunately, the image disk storage product provides limited storage capacity. Because For the above and other reasons (such as power consumption and cost), the image disk is not used in other computer products. Therefore, it is not easy to achieve small hard type by one of the digital cameras to exchange data with other computer products such as a laptop Disk drives have been proposed for portable computer products. For example, US Patent Gazette No. 5,469,314, published on November 21, 1995, Morehouse et al. Discloses a hard disk drive for use in portable computers. In this case, a hard disk drive with a diameter of about 50 mm is described. In describing many problems of portable computers due to storage needs At the same time, the obvious problem of the mobility of the storage medium still exists. Similar to a standard-sized magnetic disk cartridge, the small-sized magnetic disk cartridge includes a flexible disk disposed in a hard case.

A similar standard size magnetic disk cartridge is disclosed in U.S. Patent Gazette Amendment No. 32'876 (Wakabayashi et al.). The

The Wakabayashi et al. Patent also refers to a magnetic disk cartridge containing a flexible disk having a central center (i.e., a pivot) and used to store information. The magnetic disk cartridge includes a magnetic disk attached to a pivot. Flexible disk. The disk and pivot assembly are placed between an upper cover and a lower cover. The lid of Wakabayashi et al. Rotates inside the cartridge and includes a metal sheet that slides over the disk access port to cover a disk head access opening. The inner lid works well for disks with low rotation speeds, and aerodynamics are not a problem at low rotation speeds. However, in a magnetic disk having a relatively high rotation speed, the cover can change the aerodynamics of the disk rotation and affect the performance. Most cartridges use a gasket inside the cartridge. For example, as disclosed in U.S. Patent Gazette Nos. 4,750,075, 5,006,948, 5,216,566, and 5,083,231, textile pads are typically attached to magnetic disk enclosures The upper and lower halves allow the textile pad to lie on a flat surface on the disk. However, the gasket is not typically attached to the surface of the lid. With an internal lid, the disk can be exposed on a bare surface, which may scratch or damage the disk surface. Therefore, it is necessary to improve the disk pad. ^ Invention key 5 (please read the back of the matter before JAe Ben Ting)

The invention description (V <) leaves a space for compensation between and around. The use-inner lid housing provides several advantages over other inner lid designs. These advantages include improved ruggedness of the magnetic cartridge 10, improved aerodynamics of the magnetic disk 14 and improved lid control. The improved robustness is caused by the magnetic disk cartridge 10 having two layers of cover material (lid 16 and cover 18) for preventing mishandling. The improved magnetic disk 14 aerodynamic system is completely controlled due to the space where the magnetic disk 14 rotates, and it is not disturbed by the characteristics of other internal mechanisms. For example, in the design of other internal covers, the shrunk cover Covers only a portion of the rotating disk, thus increasing the possibility of airflow disturbances. An example of the last advantage of the lid of the present invention is the improved lid opening control. The lid typically has a -deflection mechanism to close the lid. In the lid design of the present invention, a spring 21 provides this bias. Here, the spring 21 can be positioned behind the magnetic disk cartridge 10 and still control the operation of the cover 16. When the cover combination 2 8 is completed, the media 1 4 is exposed through the media access opening 4 1 6. However, as described in more detail below, when the lid access opening 4 1 6 is aligned with the magazine case access opening 4 1 8 within the magazine 10, only the disk Box 10 is accessed from outside.

Description of Invention (i L) Figures 10 and 10 illustrate the " Open # & 'Close #' operation of the cover housing with the spring mechanism 22. Figure 6 is a top view of the cartridge 10 in the closed position, with the upper half of the cartridge cover removed for clarity. The top view of the magnetic disk cartridge 10 in the open position in FIG. 7 also removes the magnetic disk cartridge cover 18 a for easy viewing. The moving force that biases the cover 16 toward the closed position is provided by a compression spring 23 on the solitary path. As described above, the compression spring 2 1 slides over the isolated guide wire 23, which is attached to the U-shaped stabilizer 2 within the holes 1 2 4 a and 1 2 4 b The end of 4. After attaching the compression spring 23 to the guide wire 21, the spring 23 follows the arc path established by the guide wire 21. Other structures can also form a curved spring path. For example, an arc-shaped channel cut to fit the stabilizer 24 can also provide a spring 2 3 -curved path. However, the use of the guide wire 2 3 is a better method because it facilitates the structure of the magnetic disk cartridge by improving the use of the spring 21. That is, the spring 21 easily conforms to the shape of the guide wire which is subsequently attached to the stabilizer 24. The cover case 16 has an extension fin 1 7 0 that couples and transmits a force between the cover 16 and the spring 21. The wing 1 7 is preferably formed within the lid 16 but it may also be an alternative way of attaching to the lid housing 16 as a separate part by welding, for example. The fins 17 are extended outward by the cover 16 so that they extend into the spring path and cover the guide wire 2 3 ° When the magnetic disk cartridge 10 is in the closed position, the compression spring 21 is combined with the fins 17 and The lid 16 is biased toward the closed position.

When the rotational force is removed from the cover housing 16, the spring 21 presses the cover housing back to the closed position. The magnetic disk cartridge 10 has several features (which are best described in accordance with Figures 9 and 10), and these features cooperate with the operation of the magnetic disk drive 50 0 to 16. These features include capturing ears 5 1 and protruding The part 5 1 8 and the shrink hole 6 1 8 (Figure 5 shows another view of the closed lid 8. The cap capture ear 5 1 6 protrudes outward from the radius of the cover 16. The capture ear 516 is in the operation of the cover 16. Provides two important functions: first, it provides a stop function when the spring 21 biases the cover 16 toward the closed position; second, it provides a mechanism for coupling with the magnetic drive 50, The lid cover 16 can be opened during the insertion of the drive 50. When the lid 16 is rotated clockwise, the function of the capture ear 5 1 6 captures the effect. When rotated to the closed position, the capture ear 16 5 1 6 combines the edge of the disk enclosure cover, and thus stops the rotation of the cover 16. Referring to Figures 1 A to 1 1E, the operation of the cover cover 16 and the drive 50 is further advanced. Explanation: Referring to FIG. 1A, the magnetic disk cover 18 also has a flat protruding portion 5 1 8 which is adjacent to the catch ear 51 6 when the lid cover 16 is in the closed position. The upper half of the disk case cover 1 8 a is provided with a cover 7 1 8 near the flat protruding part 5 1 8. The cover 7 1 8 covers the capture when the disk cartridge is not within the drive 50.

Description of the invention (/ Magic 8 a 'The hook portion 4 8 a has-an upright fin portion 1 4 8 which is suitable for engaging the lid cover 1 6. When the magnetic disk case 10 is inserted When the drive is 50, the upright fin portion 1 4 8 meshes with the flat protruding portion 5 1 8. The fairly flat and wide upright fin 1 4 8 and the flat protruding portion 5 1 8 provide a provision area to ensure The lid lever 48 is properly and securely engaged with the lid 16. In addition, the flat protruding portion 5 1 8 enhances the pressure angle, making it easier to start the cover 16 to rotate. When properly engaged, a corner of the upright fin 5 1 6 abuts against the capture ear 5 1 6. -The shrink hole 618 is cut in the lower half 1 8 b of the magazine cover. The shrink hole 6 1 8 allows the upright tab to shrink along the capture ear 5 1 6 to enter the magazine cover 18 and remove the pathways for components leaving other disk drives 5 0. This ability to retract the lid opening mechanism and the ability to capture the ear 5 1 6 results in a larger disk access opening. Figure 1 1E shows that the magnetic disk cartridge 50 is loaded into the magnetic disk drive 50 by the lever 4 8 and the cover 16 is completely retracted. The cover lever 4 is pivoted to its distal end 4 8 b to drive the frame adjacent to the front part of the drive 5 0 5 p cover lever 4 8 is a spring (not shown) to clockwise (As shown in Figures 1 1 Β to 1 1 Ε). Due to this deflection, when the cartridge 10 is not within the drive 50, the lever 48 is pivoted to a position shown in FIG. 11B. As shown in FIG. 11C, when the magnetic disk cartridge 10 is placed in the magnetic disk drive 50, the protruding portion 5 1 8 of the magnetic disk cartridge 10 and the cover bar 48 are chewed.

Description of the invention (The insertion force of the magnetic disk cartridge * 1 0 (applied by the user) will further insert the magnetic disk cartridge into the magnetic disk drive 50, which will cause the cover 16 and the bar 4 to be longitudinally aligned to the front and rear. Rotate counterclockwise. The rotating force of the lever 4 8 against the clockwise spring biasing force loads the spring of the lever 4 8. Similarly, the lid 1 6 resists the spring 2 1 the biasing force loads the lid spring 2 1 Therefore, when the cartridge 10 is ejected by the drive 50, the spring 21 causes the cover 16 to close quickly, and the lever 4 8 returns to a position close to the position shown in Fig. 1 1 B. 1 1 Figure D shows the first stage of rotation of the cover 16 when the cartridge 10 is further moved into the drive 50. Figure 1 1 E shows the status of the cartridge 10 fully inserted. The cover 16 and the lever 4 8 basically above The reverse order of the contents is separated with Figures 1 A to 1 1 E. However, the cartridge 10 is ejected from the drive 50 by the help of the spring 2 1 of the cartridge 10, especially when the magnetic When the cartridge 10 is ejected by the disk drive 50, the force of the spring 21 causes the lid 16 to rotate clockwise. This spring force causes the catching ear 5 1 6 to hit the upright wing 1 4 8. This force also causes the magnetic The magazine 10 is moved outward by the drive 10. Of course, when the cover lever moves clockwise toward its pre-loaded position, the force to move the magazine outwards is reduced by 30 drives. Further details of the ejection mechanism and the ejection mechanism are described in the patent application serial number 08 / 968,561 in the application, which was filed on November 12, 1997.

Description of the invention (—) Including—1 solid flat bottom surface 1 2 e, an inner ring 1 2 c and—the outer peripheral edge 1 2 b. Figure 12 also shows that the bottom cover half 1 8 b has a rounded edge portion 2 1 8 c near the drive access hole 2 1 8 b. The hub 12 and the rounded edge 2 1 c interact with each other to restrict the lateral movement of the magnetic sheet 14 within the disk case cover 18. The lateral movement of the unrestricted magnetic sheet 14 within the magnetic disk cartridge 10 can cause the edge of the magnetic sheet 14 to hit the inner peripheral surface of the cover 16. Such a collision may damage the magnetic disk 14 and cause data loss or deterioration. Referring to Figure 13 (Section 12 of Figure 12 along the line 13-13), the hub 12 and the attached magnetic disk 14 are within the magnetic disk cartridge 10, and the distance shown by the line 1 12 is used Lateral movement (in X and y planes). However, the hub 12 projects outward from the drive access hole 2 1 8 b (see also Fig. 6). The protrusion of the hub 12 is much more significant than that of a conventional floppy disk cartridge. The protrusion is so significant that even if the hub 12 is pushed up into the magnetic disk 10, the hub 12 is still driven by the drive access hole 2. 1 8 b projects outward. The overall effect of the projection of the hub is to prevent the magnetic piece 14 from moving laterally, so that its edge contacts the inner peripheral surface of the cover 16. During the time when the magnetic disk cartridge 10 is inserted into the magnetic disk drive 50, the main shaft remains fixed, and the magnetic disk cartridge 10 slides on a plane relative to the main shaft 40. In other words, unlike the typical magazine placement mechanism used in other disk drive systems, in the disk drive 50 and the disk magazine 10 of the present invention, in the 2-axis direction, the disk magazine 10 or the spindle 4 0 did not move. Therefore 'in order to load the kill 12 on the main shaft 40, when the hub 12 slides along the upper surface of the spindle motor 5 3 and exceeds the main shaft 40, the hub 12 makes a movement on 2 axes 22 ---- ----- 装 ------ ^ ------ ^ (Please read the following first: ^ Yiluo item, then "quote" This paper is based on the Chinese National Standard ( € ^ 5), \ 4 is now 12 Chuan \ 2 < ^ Public President > Ministry of Economic Affairs ^^ 4 [Lu & Co., Ltd. printed A7 _ B7 V. Description of the invention (> /). The movements on the two axes can be explained with reference to Figures 14a to 1c. Figures 1A to 14C represent the cross-sectional views of the magnetic disk box i 0 and the magnetic disk. The magnetic disk box 10 and Disk drive 50 along line ii ^ 4_1 4 corresponds to disk El 0 and drive ^ in FIG. 11. Evening relative position. The peripheral edge 12b is preferably formed as a ~ == face, and the angular outer surface is adapted to be combined with a circular isolated edge of the spindle access opening when it moves upwards into the cover 丨 8. For the preferred angle of the external angle, g 'is about 45 degrees. More preferably, the peripheral outer edge 12b substantially forms a ring surrounding the peripheral surface of the valley 12. However, other structures can perform similar functions, such as handle-shaped fingers with angled surfaces, rather than the fixed annular surface illustrated in the drawings. Similarly, the inner ring surface 1 2 c, which is substantially preferably circular, can also include a different form, such as a set of fingers. The inner ring surface 1 2 c also has a preferred angle B ν of approximately 45 degrees. As shown in the cross-sectional views, the hub 12 has a stepped side profile. The magnetic piece 14 is attached to the hub 12 along the uppermost surface 12 h of the hub 12. From the top surface 12h to the next-order system surface 12j, it forms the top surface of the peripheral outer edge 1 2b. This stage provides a gap-13 between the hub 12 and the magnetic sheet 14. As explained in more detail below, the gap 13 provides more flexibility in the vertical movement of the inner hub 12 of the disk cartridge 10. The spindle motor 40 has several features suitable for interaction with the hub 12. In particular, the 'major axis 40' includes a base point 40a (provided by a raised ring), a circular protruding surface 4Ob, and a conical introduction groove 4oC. All the above features work together to make the hub 12 and the main shaft 4 0 23; | + 衣 ------ ^ ------ Φ (Jing first read the back :; read the sound item and then ^. ,; ^ 本 汗) Good paper standards are applicable to the National Standards of China (CNS) Λ4 Appearance (: MU, 297 mm) 411445 A7 ---__ ^ ___ 5. Description of the invention (>) Combined with S * separation. In addition The top surface of the main shaft 40 is magnetically susceptible to attraction. It magnetically couples the hub 12 to the main shaft 4 0 ^ Very interestingly, the hub 12 and the main shaft 40 are combined and separated from each other without the magnetic cartridge 10 Displacement occurs perpendicular to the plane of the plane of the disk drive (that is, in the direction of the Z axis) or the spindle motor is displaced. Therefore, the height of the disk drive 10 is lower than the height of the spindle or the disk cartridge. When the disk cartridge is linear Ground (that is, along a plane that is substantially parallel to the X axis) when the disk drive is moved in and out, the hub 12 and the media 14 are moved within the casing 18 along the Z axis direction. There is no need for additional space inside the casing 18 to accommodate the movement in the Z-axis direction of the hub 12, and the available space has allowed the magnetic sheet 14 to rotate freely within the casing 18. The present invention can even make 5 The space provided by the inch magazine is a small internal magazine space and functions correctly. As shown in Figure 4A, during the time when the magazine 10 is inserted into the drive 50, the hub 12 is in the frame. 5 7 On the bottom of the relatively flat outline and on the top surface of the main shaft 40, slide on the surface of the inner ring 1 2 C.

At this time, the magnetic force provided by the main shaft 40 attracts and pulls the hub 12 to combine with the main shaft 40, causing the inner ring surface 1 2 c to extend into the conical introduction groove. 4 0 c. As shown in FIG. 4B, the angle between the introduction groove 40 C and the inner ring surface 1 2 c is preferably about 45 degrees, when the hub 12 is pulled to a predetermined position, the hub 1 2 is aligned with the main axis 40 correctly in the center. In particular, the inner ring 1 2 c forms a conical male surface corresponding to the conical female opening of the introduction groove 40 c. When the two conical surfaces are combined, the inner ring 1 2 c is guided by the conical introduction groove 4 0 c. In addition, the relatively large inner ring surface 1 2 c diameter (as measured across the hub 12) and the relatively large conical lead-in groove 4 0 c diameter ensure that the hub 12 is aligned with the main shaft 40 fairly accurately. 〇 When the cartridge 10 is ejected by the drive 50, the hub 12 is separated again by the main shaft 40 without vertical movement relative to the cartridge 10 of the drive 50 (only the hub 12 and the media 14 moves in the Z axis). As shown in FIG. 4C, when the magnetic disk cartridge 10 starts to be ejected by the magnetic disk drive 50, the magnetic disk cartridge casing 18 is moved outward from the magnetic disk drive 50. During the outward movement of the magnetic disk cover 18, the hub 12-starting to remain attached to the main shaft 40. In order to detach the hub 12, an additional amount needs to be applied. The required power is provided by the movement of the magazine housing 18 relative to the hub 12. The magnetic disk cover 18 has a downwardly projecting bolt 20 and a rounded edge 18 C. The downwardly projecting bolt 20 and a rounded edge 18 C cooperate with the hub 12 to assist in the separation. When the bolt 2 When 0 hits the side wall of the hole 1 2 a, the separation will start, which is true. __ 25 This paper size applies the Chinese National Standard (CNS) Λ4 specification (2 丨 0, < 29?

Description of the invention) At 8 o'clock in nature, the circular edge portion 1 8 c is in contact with the angular outer peripheral edge 1 2 b. When the cover 18 continues to move outward, the horizontal movement of the circular edge 18 c against the angular peripheral edge 1 2 b (along the X axis) causes the hub 12 to rise. The impact of the combination of the bolt 20 and the raised cover 18 b causes the hub 12 to lean towards the reference 40 a. When the hub 12 is tilted, the inner ring surface is also tilted. When the inner ring 12 c passes the top surface 40 d of the main shaft 40, the hub 12 can move outward from the magnetic disk cartridge 10. When the hub 12 is moved outward, the angled inner ring surface 12g is combined with the angled main shaft introduction groove surface 40c. Because both surfaces have angles, the hub 12 slides upwards on the side of the introduction groove surface 4 0 c. As shown in Figure 1D, when the bottom surface 1 2 f of the inner ring 1 2 c passes through the main shaft 40 At the reference 40a, the hub 12 can move relative to the magnetic disk cartridge 10. Thereafter, the bolt 20 causes the hub 12 and the disk cover 18 to run on the reference. The force of the bolt 20 continuously pulls the hub 12 to move on the surface of the spindle motor 53 and the frame 57, until the magnetic disk cartridge 10 is discharged by the magnetic disk drive 50. The stepped shape of the hub 12 allows additional space when the hub 12 is tilted inside the magnetic disk cartridge 10. That is, without a stepped hub *, the inclination will cause the top surface of the hub 12 to hit the inner top surface of the casing 18, and the interference hub 12 will be separated by the main shaft 40. In addition, the stepped hub allows the magnet piece 14 to bend when the hub 12 is tilted during separation. As shown in Figure 14A, the hub 12 moves in the Z-axis direction when the cartridge 10 is inserted into the drive 50. Therefore, the magnetic sheet 14 is pushed up to the upper half of the lid cover. The internal surface of 1 6 a and abuts the pad 1 5 a (_ 26 The standard of this paper wave is applicable to the Chinese National Standard (CNS) Λ4 Appearance (:! 丨 0, < 297 公帑); | > --ΐτ ------ 0 (Please read the reverse; .i Italian Cup item Ben Ting) Ministry of Economic Affairs ¾ °. ¾ Called to leave; printed by fif cooperative 411 ^ 45 A7 ______B7_ 5. Description of the invention ( 〆) For the sake of clarity, it is not shown in this figure). The upward movement of the hub 12 allows it to pass through the top surface of the main shaft 40. However, due to the side effect of the upward position of the magnetic sheet 14, the edge of the magnetic sheet 14 must be adjusted downward to pass through the head load slope 47, which will be described in more detail later. Figure 15A shows a diagram of a load ramp according to the present invention. The load ramp 47 includes a base 67, a head guard 61, pivot arms 60a and 60b, and abutment sections 6a and 66. b, pivot pin 65 and compression spring 69. Each pivot arm 60 includes a beveled end portion 64 and a tail portion 63. The pivot arms 60 a and 60 b are arranged to be pivotally connected to the pivot bolt 65 in an open position. In the open position, the two beveled ends are rotated apart by a pivot. In the closed position, the two beveled ends rotate close to each other according to the pivot. The spring 69 is disposed between the pivot arms 60a and 60b, so that the pivot arms 60a and 60b are biased toward the closed position. When the tail portions 63a and 63b of the pivot arms 60a and β Ob are biased to the closed position, they are combined with the corresponding adjacent portions 6 6 a and 6 6 b, respectively, so as to restrict the pivot arms 60 a and 60. b rotation operation. The base 6 7 also includes a hole 70 attached to the frame 57 by a screw or other commonly used attachment means. The head guard 6 1 extends from the base 6 7 and provides opposing faces 6 1 a and 6 1 b. Each of the opposing faces 6 1 a and y: > 6 1 b has front face portions 6 2 a and 6 2 b of ^^ 0 face, respectively. When the starter 49 is stopped, each of these faces 6 1 a and 6 1 b provides a surface of the head 4. Reference is now made to Figures 15B and 15C which show a side view of the load ramp 47.

Therefore, the distance between the end portions 6 4 a and 6 4 b is maximized. When the distance is maximized, the medium 1 4 entering between the end portions 6 4 a and 6 4 b has sufficient space to shake during loading without causing a collision between the medium 14 and the load slope 4 7 . In Fig. 15C, the pivot arms 60a and 60b are in the closed position. Once the medium is fully inserted into the drive 50, the pivot arms 60a and 60b can safely approach the medium 14 without damaging the medium 14. With the pivot arms 60 a and 60 b in the closed position, the head 46 can safely move between the media 14 and the load ramp 47. The line is printed by the Ministry of Economy! Λ_1 is printed by the S Industry Consumer Cooperative because the hub 12 and the magnetic disk 14 are moved upward from the valley 12 and slide on the frame 57. When the hub 12 is compressed within the pad 15a, the magnetic sheet 14 is forced out of the plane. Applying a force to the magnetic sheet in this manner and moving it out of the plane causes severe distortion of the outer peripheral edge of the magnetic sheet 14. This edge twisting in turn enables the magnetic sheet 14 to move above the top surface of the load beveled end portion 64, instead of passing correctly between the end portions 6 4a and 6 4b. It is necessary to adjust the magnetic disk 14 at the disk access opening to ensure that the magnetic disk 14 passes correctly between the load beveled end portions 6 4 a and 6 4 b.

The thickness of the twist canceller is at least one thickness of the pad 15 a, and the thickness is not greater than about the cover Half of the space between the upper and lower halves of the housing. More preferably, it is about 0, 2 mm thick. The width of the twist canceller 11 is limited to the relatively small size of the drive 10 of the present case. That is, it is further limited by the distance between the edge of the disk access opening 4 1 6 a and the hub 12. Therefore, the width is about 1 to 2 cm In between, it is preferably about 1, 5 mm. Preferably, the raised surface is formed by pressing the twist canceller directly into the upper half of the lid casing 2 1 6 a. Furthermore, The cover gasket 1 5 a is preferably attached to the top surface of the raised surface to protect the magnetic sheet 14 from direct metal contact with the media distortion canceller 1 1. The media distortion canceller 1 1 is preferred It is arc-shaped. It is better that the arc is a part of a circle so that it is concentric with the magnetic sheet 14. However, the media distortion canceller 11 can also be substantially straight. Therefore, when When the magazine is assembled, the media distortion canceller 11 provides a watershed that projects downward from the upper surface of the magazine 10. This protruding surface ensures that the magnetic disk 14 is on the upper and lower half of the magazine 18a and 18b. The force between them is downward 'and toward the plane closer to the center. Therefore, the magnetic disk 14 closer to the center is more between the end 6 6 of the head load bevel during the time when the cartridge is inserted into the drive 50. Reliable crossing.
