Abstract

A disk drive includes a housing, a cartridge tray, and a cam plate. The cartridge tray is adapted to hold a cartridge that includes a data storage disk. The housing has a pair of vertical cartridge tray pin slots which hold tray pins that are part of the cartridge tray. The cam plate includes a pair of cam slots formed at an oblique angle to the cartridge tray pin slots. The tray pins extend through the cam slots into the cartridge tray pin slots. Movement of the cam plate back and forth causes the tray pins and cartridge tray to move vertically between a loaded position, where data can be read from or written to the data storage disk, to an unloaded position. A disk drive also contains a pair of spring elements which act as eject limiters, engaging catches on a cartridge to prevent the cartridge from being completely ejected from the drive. The cartridge is positioned in the X and Y dimensions by contact between an alignment opening in the cartridge and an XY alignment pin in the disk drive and in the theta (rotational) dimension by contact between an edge of the cartridge and a theta datum in the disk drive. The cartridge is positioned in the Z dimension by contact between the cartridge and at least three Z datums. The disk drive also includes a picker arm for opening a shutter on the cartridge, thereby exposing a data storage disk, as said cartridge is inserted into said disk drive.

Description of the invention (15) When E 1 0 is inserted 'The angle of the picker arm 2 4 6 relative to the leading edge of the shutter 1 〇6 Should be too large. The friction between the shutter 10 and the casing 10 may be too large when the angle is too large to suppress or prevent the shutter 106 from opening. The opening force applied by the shutter opening surface 2 4 6 B to the shutter 1 〇6 must overcome the friction between the shutter 106 and the housing 1 〇2. Therefore, the picker arm 2 4 6 includes a protruding portion 2 4 6 C, which reduces the effective angle between the picker arm 2 4 6 and the leading edge of the shutter 106. The nineteenth figure D shows the relationship between the shutter 1 〇6 and the picker arm 2 4 6 at the initial contact point. The angle α indicates that if there is no protrusion 2 4 6 C and the rotation point of the picker arm 2 4 6 is at At the point 2 4 9, the effective angle between the picker arm 2 4 6 and the front edge 10 6E of the shutter 106. The angle call indicates the effective angle between the picker arm 246 and the leading edge ι〇06Ε and the rotation point is at the point 2 4 8. As shown, the angle / 5 is smaller than the angle a ° and 'when the shutter 1 0 6 is fully opened, the effective angle between the picker arm 2 4 6 and the shutter 1 0 6 leading edge 1 06 E should be as small as possible, The protrusion 2 4 6 C also minimizes this angle. The shutter 1 06 should be opened to a repeatable position to provide the operating distance of the internal components of the disc player 2 0. This small angle makes the opening position of the shutter 1 0 6 small relative to the movement of the cassette 1 0 on the gamma axis. Sensitivity is minimized, which can be caused by the manufacturing tolerances of the part and by the expected movement of the cassette 10 when the cassette is located at the χγ correction pin 209, as described below. When the cassette 10 is fully inserted into the disc drive 20, the presence of 2 46 C also provides the distance of the cassette. The picker arm 2 4 6 also includes the guide rod surface 2 4 6 D, as shown in Figure 19a-19C, which provides the surface of the picker arm 2 4 6 and the cover 1 0 1 (Shown in the third figure B) the flat, rotating interface and preventing the protrusion 246A from sliding toward the inner plastic of E 1 0. The role of this guide rod reduces friction between the picker arm 2 4 6 and the shield 10 6. This reduced friction will inevitably reduce the insertion of the protrusion 2 4 6 A

As shown in FIG. 19C, the protrusion 246A "protrudes out of", the shutter opening surface 246B, and a bend or inflection point is generated at the connection between the protrusion 246 A and the shutter opening surface 246B 246G, when the shutter 106 is in its fully open position (as shown in the second picture), the turning point 246G provides a positive locking force to the contact edge of the shutter 106 and prevents the shutter from self-shock due to impact or vibration 1 0 6 is disengaged. Still referring to the nineteenth figure A to the nineteenth figure c, the protrusion 2 4 6 A has an angled back wall 2 4 6 E 'when the shutter 1 〇 6 is in its fully open position (refer to the eighth figure And the ninth figure), the back wall 246E engages the hanging buckle 138 of the lock shutter 106. As a result of this contact, when the cassette 1 〇 is to be removed from the disc player 2 〇, the back wall 2 4 6 E provides a shutter 1 0 6 The positive closing force and thus prevent the shutter from being trapped, and fully opened. Once the shutter 1 06 begins to close, the shutter returns to the spring i ^ to take over. / The picker arm 246 also includes a stop Surface 246 ?, which corresponds to the corresponding stop surface 2 4 5 on the pan 244 (refer to the second time chart and the second 19)), so when the disc player 20 is empty, the picker arm 246 can be held in the correct position, so that when the cassette 10 is inserted into the disc player 20, the protrusion 2 4 6 A can be appropriately Spray cover shutter locking device 128 and shutter 106. Before the cassette 10 is inserted into the disc drive 20: The position of the picker arm 2 4 6 is plannedly fixed so that the picker arm 2 u engages the shutter 106 on the surface 139 , The surface 139 is 120 before the opening of the shutter 106 (coming according to the third figure).

Twenty-first Figure A is a cross-sectional view similar to Figure 28, showing that cassette 10 is fully inserted into cassette 244. The picker arm 24 6 is rotated by the force of the picker arm spring 250 $ until the picker arm 24 6 is in the retracted position. In this specific example, 'it is basically flat against the back of the tray 2 4 4 and the shutter 1 〇 6 (not shown) is fully open. Importantly, as shown in the detailed view of the thirty-first figure B, the box flaps 2 08A and 2 08 B on the door have engaged the shoulder corners 152A and 2 B of the box 10 (refer to FIG. _), And thus The prevention cassette 10 is thrown out from the disc player by the force from the picker arm spring and the shutter return spring Ho. The twenty-second figure is a perspective view from the bottom, showing the cassette 10 is fully inserted into the disc 244, and the cam plate 252 is also shown. Cassettes 10 to 31, Fig. 31, Fig. 31, and Fig. 32 are inserted upright as shown in action # 1 in Fig. 41. _ At this time, as shown in Figure 33A to Figure 33C, the box 10 causes the shield or flag 2 5 3 to interrupt the light beam generated by the light emitting diode (LED) 2 5 5 Finally, this is detected by the photo sensor 257, which sends out a signal of a stimulus box loading / unloading motor and a lead screw mechanism 2 2 9. Stimulus loading Twenty-third Figure A is a perspective view of the disc player 20 with the tray 2 4 4 removed. Figures /, Figures B and 6C are top views of the disc player 20, in particular Figures 6 to 6 / C show a flag 2 5 3 mounted on the housing 2 via a flag spring 2 6 1 . The combination of the flag 2 5 3 and the flag spring 2 6 1 is not necessarily installed in the housing 2 02 as shown in Figs. For example, the application No. 6 0/2 6 5, 8 3 0, which was filed on January 31, 2001, is titled as a cartridge loading mechanism for a data storage disc. The flag and the flag spring can be installed in plate. The other descriptions assume that the flag 2 5 3 and the flag spring 261 are mounted on the housing 2 0 2 as shown in the sixth diagram A to the sixth diagram c. ,

The flag 2 53 may be formed of an opaque material, in a preferred embodiment

1226038 _ Case No. 91101306 Amendment 5. In the description of the invention (18) ', the flag spring 261 is formed of metal and other flexible materials and includes the first and second endpoints. The first end of the flag spring 2 6 1 may be fixedly connected to the housing 2 0 2 using a method such as an adhesive or welding. The second end of the flag spring 2 6 1 is connected to the flag 2 5 3. In a specific embodiment, the flag 2 5 3 and the flag impeachment 2 61 are formed of the same piece of flat metal, so that the flag 2 5 3 is integrally connected to the flag spring 2 6 1. As described more fully below, the flag 2 5 3 can be moved between the beam interruption and beam receiving positions. The sixth diagram A to the sixth diagram B show the flag 2 5 3 is at the beam interruption position, and the sixth diagram C shows the flag 2 5 3 is at the beam receiving position. The flag spring 2 6 1 biases the flag 2 5 3 toward the beam receiving position. L E D 2 5 5 and photo sensor 2 5 7 are mounted on the housing 20 2 via a printed circuit board (not shown). The combination of the flag 253, the LED 2 5 5 and the light sensor 2 5 7 represents a specific embodiment of a device for detecting the presence of the cassette 10 in the disc drive. When the LED 25 5 is active, it will generate a light beam between the LED 25 5 and the photo sensor 25 7. When the photo sensor 2 5 7 is active, it will generate a light beam in response to receiving the light beam generated by the LED 2 5 5 or In response to the interruption of the light beam generated by LED 255. Other narratives assume that the light sensor 2 5 7 generates a signal in response to the interruption of the light beam generated by 1 E D 2 5 5. The flag 2 5 3 can be moved between the beam interruption position and the beam reception position. At the beam interruption position, as shown in Figure 33A and Figure 33b, the flag 2 5 3 is located between the LED 2 5 5 and the photo sensor 2 5 7 so that the flag 253 is interrupted by the photo sensor 2 5 7 received beams. In other words, when the flag 2 5 3 is at the beam interruption position, the 'flag 2 5 3 covers the sensor 2 5 7 so that it does not receive light from 1 E D 2 5 5. At the beam receiving position, as shown in the sixth figure C, the flag 2 5 3 is removed from the LED 2 5 5 and the light sensor 2 5 7 so that the light sensor 2 5 7 can receive the light generated by the LED 2 5 5 Beam.

Description of the invention (19) Flag 25 3-generally at the beam receiving position, and when the cassette is fully inserted into the cassette 244, the flag 2 5 3 was moved from its beam receiving position to the beam interruption position. In a specific embodiment, when the cassette 10 is inserted into the disc 2 44, the cassette 10 directly or indirectly engages and moves the flag 2 53 to its beam interruption position. When Marina 1 0 is inserted into the plate 2 4 4, the cassette 10 indirectly resonates and moves the flag 2 5 3 to its beam interruption position. When the cassette 10 is removed from the disk 244, the flag spring 261 returns the flag 2 5 3 to its beam receiving position shown in FIG. 6C. When the cassette 10 has been inserted into the disc 2 4 4, the disc pins 2 6 4 and 2 6 6 are close to the disc pin slots 298 and 300 (as shown in the twenty-sixth figure). The cam plate 25 2 is approximately at the position shown in the twenty-second figure. The cassette loading / unloading motor and the lead screw mechanism 2 2 9 move to the rear of the disc drive 2 0. This movement rotates the lever arm 2 clockwise and moves the cam The board 2 5 2 pulls towards the front of the disc drive 20, the cam slots 2 74, 2 76, the disk pins 2 6 4, 2 6 6 and the disk pin slots 2 9 8, 3 0 0 mechanical interaction ( As a result), the tray 244 starts to move downward. As shown in Figure 34A, when the cassette 10 is fully inserted into the cassette tray 24, the leading edge 3 of the cassette 10 is directly positioned on the backside preventer 2 i 2 of the housing 2 0 2 ( (Backside preventer 21 2 is shown in Figures 14 and 15). The thirty-fourth figure A and the thirty-fourth figure B show the positions when the descent of the cassette 10 has just started. As shown, the leading edge 3 0 4 is in contact with the top surface of the back stop 2 1 2 but Overall, the cassette 10 is still basically horizontal. With the box 10 lowered slightly, the door 2 06 was further opened slightly (compared to the positions in Figure 31 and Figure 31) 'and the cam 2 was released on the door 2 06 The continuous contact between the 10 and £ 10 surfaces caused the cassette 10 to release from the cassette flaps 2 08A, 2 08B.

This method is continued until the lower surface of E 10 is in contact with the z-reference and 2 2 6, as mentioned above, the reference 22 and the Toda agan and 22 2 are used as a single reference function. When needed, E 10 is bent to ensure each contact with z-reference 218, and 2 2 6. In this position, the well disc a 1 and the disc 1 08 are suitably located at the spindle motor 23 0 so that the disc 108 can rotate freely without touching the cassette housings 102 and 104. This is the playback position of E 10, in this case Shown in Figure 38. At this time, in the specific embodiment, the E loading / unloading motor is stopped and thereby maintained on the Z-references 218, 220/222, 224, and 22 6 at £ 244, passing through K 10 to the peripheral 20 2 Between forces. This system including the lead screw, lever arm, lever arm 284 and cam slot 2 7 4 2 7 6 is essentially to prevent the cam plate 2 5 2 from being driven backwards, and via the S 10 to Z reference 218, 220/222, 224 and 22 6 Maintain a refreshing load.

When the cassette 10 is located at the playback position, it is accurately positioned at the correct position as follows to read data from or write data to the optical disc 10 8. During the loading method, the cassette 10 is appropriately positioned at the datum of the X, γ, 2 and angular axes. Box 1 〇 Correction feature 1 4 3 is positioned on the X and γ axis by the biasing action of the picker arm spring 2 5 0 to force the V-shape portion 1 4 3 of the correction feature 1 4 8 against the X Υ correction connection Feet 2 0 9. The box 10 is positioned on the angle axis by the biasing effect of the shutter return spring ιο to force the box housing 102 against the angle reference 214. Thus, £ 10 is positioned by the XY correction pins 209 and the angle reference 214, respectively. On X, γ, and angular axes. The cassette 10 is positioned on the lower surface of the housing 10 by the clamping action of the cassette 244. The cassette 244 is positioned by the cam plate 2 52, the lever arm 284 and the lead screw (not shown) toward the Z reference 218, 220 / Driven by 222 '224 and 22 6, Kun 10 was determined accordingly.

Holes are provided at the appropriate positions of the tray plate 2 4 4 and the cam plate 2 5 2 to ensure the angle reference 2 1 4, the angle limiter surface 2 1 6 and the Y limiter 2 1 1 can contact the corresponding surfaces of the box 10 For example, the angle reference 2 1 4 and the angle limiter 2 j 6 contact the box 10 through the openings 2 6 0 and 2 6 2, as shown in the twentieth and thirty-second figures. As shown in Figures 29, 30, and 32, the surface of the cassette 10 contacting the z-reference 218, 2 2 0/22 2, 224, and 2 2 6 passes through the opening area of the £ 244 In the exposure, the X limiters 2 9 4 and 2 9 6 do not contact Kuang itself, but contact the surface of the cam plate 2 5 2. In some embodiments, there may be only three Z-references, in which case E does not need to be flexible to fully locate the Z-references. In other embodiments, there may be five or more Z-references. Therefore, the position of S 1 0 is dynamically defined by six points: two points of contact between the χγ correction pin 2 0 9 and the V-shape portion 1 48 of the correction feature i 43; here! £ 丨 〇 One point of contact with the angle reference 2 1 4 and three points of contact between the magazine 1 0 and the z reference 0 After reading or writing data from the optical disc 1 08, a signal is Transfer to the g loading / unloading motor-lead screw device, which causes the motor to start rotating in the reverse axis, which causes the lever arm 2 8 4 to rotate in the counterclockwise direction, and moves the cam plate 2 5 2 to the rear of the disc player 20. For example, as shown in FIG. 22, when the cam plate 252 moves to the rear of the disc player 20, the cam slots 2 74, 2 7 6 force the disc pins 264, 266 (and the tray disc 244) upward to the disc pins. Slots 298, 300. This action continues until the correction feature 143 removes the χγ correction pin 209. From the time when H 10 rises from the Z reference 218, 220/222, 22 4 and 22 6 to the branch positive feature 1 4 3 and the XY correction pin 2 0 9 is removed. The box 1 0 action is shown in the forty-first figure. Action # 5.

1226038

The situation when the correction feature 143 has been removed from the χγ correction pin 209 is shown in Figure 39. As shown, the cassette stops 208A and 208 »are pressed against the flat bottom surface of the cassette 10 and do not operate to restrain the cassette i0. Therefore, since there is no component to constrain the cassette 10 to the disc player 20, the force of the spring-loaded picker arm 246 takes over and starts to cast E 1 0 from the disc player '20. ¥ The picker arm 2 4 6 continues to eject the cassette 1 from the disc player 2 0, and the projection limiters 2 68, 2 70 project 2 68A, 2 70A (shown in the twentieth figure) along the projection restriction slots 154A. , 154B (shown in the first picture) slide until the projection 2 688, 2 7 0 A enters and the projection limit slot cover 156A at the end corresponding to the projection limit slot 1 5 4 A and 1 5 4 B , 156B contact. At this time, the picker arm 24 6 did not provide enough force to overcome the resistance of the throw-out restriction slot flaps 156A, 156β and the throw-out effect of the E 10 from the disc player 2 0 was suspended. As such, the throw-out limiter 2 6 8 2 7 0 is operable to prevent the cassette 10 from being dropped from the disc player 20 to a place where the cassette 10 may be damaged, such as on the ground. The position of the cassette at this time is shown in the tenth and fortieth figures. Self-calibration feature 1 4 3 When the XY correction pin 2 0 9 has been removed until it protrudes 2 68 8, 2 70 8 and the throw-out limit slot cover 156 8, the box 156 that is not touched is shown in the fourth Eleven moves # 6. At this time, the back of ϋ 10 is protruding from the disc drive 20, and the user is free to completely remove the cassette 10 from the disc drive 20. The force exerted by the user can easily overcome the spring force of the throw-in limiters 268, 270 and cause the throw-in limiters 268, 270 to control the throw-in limit slot shutters 156A, 156B. The operation of the cassette 10 is shown in operation # 7 in FIG. 41.

The use of two plate pins has many advantages over the use of three or more plate pins. First, using two plate pins, the tray 2 4 4 can be freely rotated to a certain extent along the X axis (see for example, twenty-nine Figure), this allows the tilting of the tray 244, as shown in Figure 35a and Figure 36A, and thus assists the positioning of the cassette 10 to the XY correction pins 2 009, if used more than Two disc pins, this type of action is difficult, even if this action is achievable. In addition, the positioning of the stern axis of the two disc pins 2 6 4, 2 6 6 on the tray disc 2 4 4 can be adjusted. In order to obtain the desired distribution of the clamping force on the Z reference 2 1 8, 2 2 0/2 2 2, 2 2 4 and 2 2 6 respectively, when the cassette is fully loaded. For example, moving the disc pins 264, 2 6 around the axis 3 0 4 (and towards the door 2 6) of the leading edge of the box 10 causes a larger portion of the clamping force to be applied to the zeta reference 2 1 8 and 226 (see figure 15). Furthermore, two disc pins are used to create a unique, defined jaw line that defines the force on the Z reference. If three or more disk pins are used, depending on the manufacturing margin, the wires between the different pair of disk pins can form the operating jaws of a known cassette and are therefore compared to the 2-base The gripping force can be expected.

Description of the invention (26) 3 3 2 B whistle output gear 3 3 0. The output gear 3 3 0 is located on the shaft of the driving lead screw 3 2 4. In this way, pin 3 28 is the output point of the cassette loading / unloading motor and lead screw mechanism 22 9 and the driving lever arm 2 8 4, which drives the cam plate. 2 5 2. The cam plate 2 5 2 finally drives the disc pins 264 and 266 through the cam slots 274 and 276, and the disc pins 264 and 266 are connected to the tray disc 244. The force on the disk pins 264, 26 6 is transmitted to the cassette via the E-disk 2 4 4 and indicates that the cassette 10 is held in the playback position within the z-based = holding force. The net effect of this whole mechanism is to convert the torque of the input gear 3 2 4 in the box loading / unloading motor and guide screw, machine, 2 2 9 into the linear clamp force applied to the box.忒 The nature of the institution is to strengthen the force through the various stages of the chain

Page 36 1226038… _ Case No. 91101306 This year each month 4th Amendment _ V. One of the description of the invention (27) and its advantages is that it cannot be driven backwards by π '. In other words, for example, the force on the cassette caused by the impact event cannot move the cassette 244 or the gear 334. The mechanism cannot be driven backwards from its output (box). When the mechanism is driven by a countershaft, the benefit of the mechanism is basically the opposite of that of a mechanism when the mechanism is driven by a positive axis. Therefore, when the mechanism is driven by a countershaft, the benefit is actually a force reducer. In addition, the specific embodiment of the lead screw or electric screw element of the loading / discharging composition is specially designed to prevent backward driving. Spartan, referring to the previous data, calls this π overhaul π. Here, the Force input will drive the lead screw. Through careful selection of the design parameters listed above, backward driving of the lead screw is not possible. As pointed out in Spat, the formula for the force and torque associated with the π large maintenance π screw is as follows: Τ 二 r tW [(cos (9 η si na -β 〇 / (cos (9 n -μ! Tana) + r〇a 2 / rt] When the term in the denominator approaches zero, the transfer between structures that can be driven backwards and structures that cannot be driven backwards is achieved. The screw helix angle (a) is the desired variable. The values of other parameters are Assume the following: rt = 0 _ 7 5 mm, 0 n = approximately 0, // ^ 0.2, rc = 0.2 mm, // 2 = 0.2. Solving the spiral angle a gives a value of about 14 degrees, in other words A helix angle of less than 14 degrees will cause the lead screw not to rotate when force is applied to the nut, and a helix angle of more than 14 degrees will cause the nut to force the lead screw to rotate. When the helix angle increases, rotate the screw The required force becomes less (that is, it becomes easier to drive backwards). The helix angle of this specific embodiment has been selected to be about 4 degrees, which is safely within the critical angle range to prevent backward driving. Once Meet the condition that it will not drive backwards.

Page 37 1226038 _ Case No. 91101306 January 1st amendment_ V. A known torque input of invention description (28), the spiral angle is optimized to increase the force output at the nut, and to define the nut movement The speed is a function of the lead screw speed. The mechanism chain between the gears 3 3 4 and the trays 2 4 4 can be represented by a block diagram transfer function, as shown in Figure 43A-43. Each block in the forty-third figure A represents the interlocking mechanism elements between the gear 34 and the tray 244. The gear train coefficient (Kg) has a value of about 6. 2 5 and therefore the input and output at this stage are both torque, so Kg is a dimensionless coefficient. The lead screw coefficient (Ks) has a value of about 15. 2 8 and the unit is mm-1, because the input is torque and the output is force. The value of the lever arm coefficient (KL) is about 1. 9 0 5 and since both input and output are forces, KL is dimensionless. The value of the cam plate coefficient (K Cam) is 1.42, which is derived from the cam slot angle of 35 degrees and because the input and output are forces, the K Cam is dimensionless. The block diagram of the forty-third figure A can be represented as the equivalent block diagram in the forty-third figure B, where the coefficients Kg, Ks, KL, and K Cam have been multiplied and the resulting coefficient K is about 2 58 mm-Budang The mechanism is operated in the reverse direction or π is driven backward by π. Figure 43 shows the mechanism in Figure 43. When driven backward, the resulting gain (Kbd) of this system is .0 0 3 8 (mm), which is significantly less than 1, indicating that the power is reduced by this mechanism. Even in a system where the helix angle is larger than the critical π large inspection π angle, the force reduction by this mechanism is to prevent backward driving. The advantage of this loading mechanism over the prior art is that this mechanism does not use springs to hold the cassette in position reference. Instead, the loading mechanism uses cams, levers, lead screws and gears to provide translation (loading) of the cassette and Cartridge restrictions (cannot be driven backwards). Although specific embodiments of the present invention have been shown and described, those skilled in the art will appreciate that other changes and modifications may be made based on the meaning herein.
