By. However, the high-performance device Qingding can increase market occupancy. In order to meet the above requirements, the industry needs to pay more attention to the improved design of the optical disc drive to improve performance and reduce costs. In order to facilitate the explanation of the problems that the optical storage system faces in the face of the continuous increase in speed and cost reduction. It is well known that optical or magnetic storage systems record digital or analog data on concentric circular or spiral ti_ae disks, such as optical disks or magnetic disks (disks). The operation of digital data modulation writing head (Uri te-head) sequentially records binary data on a fast-rotating disc. For optical recording systems, digital data modulates the intensity of laser light in order to record a The series is continuous or not pitted on the disc. 'When an optical disc is inserted into the optical disc drive, the disc is first carried by a tray and transported into the optical disc drive body. A clamping mechanism is provided in the optical disc drive, which includes a magnetically conductive flat plate and a clamping disk. The magnetically permeable flat plate can be engaged with the inserted disc by actuating the magnet in the optical disc drive, and the clamping disc 2 is connected to a spindle motor through its central axis and rotates in the support of the support base, as in Taiwan One of the CD-type optical discs described in the new patent application No. 86205674, which includes a lower seat, a telescopic seat, a telescopic spring, magnetic, iron, an upper clamping cover and an upper clamping iron plate. Together constitute the clamping assembly mechanism. Although the clamping assembly mechanism can effectively clamp the inserted disc, the number of parts of the holding assembly and the complicated assembly process cause a large increase in the cost of the optical machine.

Drive rotation. The discs are assembled by a motor U in the disc holder 21. Continue to refer to FIG. 1 to explain the method for making a disc. As shown in the figure, the structure and the holding disc 4 and the holding mechanism 20 include a support base 3, a holding disc 4, and a magnetically conductive plate 5. The pedestal 3 is fixed to the newspaper above the center hole of the optical disc, (the upper side is relatively flat and flat A μ is formed into a 31 to accommodate the clamping disc 4 in a ΐ Λ square-shaped magnetically conductive plate 5. The body 1 The “board setting” actuates the plate signal to generate magnetism to attract magnetic flux. This means that it moves downwards and drives the clamping disc 4 to engage the μ center hole of the disc. Combination 1 When the clamping disc 4 rotates, the disc can also follow And the read / write head reads the required data. Further referring to FIG. 2, the structure of the holding disk 4 of the present invention will be described, in which FIG. 2 Uj is an upper view, FIG. 2 (B) is a side view, and FIG. 2 (c ) Is a back view and FIG. 2 (D) is a scraped view along line AA in FIG. 2 (A). The clamping disc 4 is a circular disc-shaped structure and is usually made of thermosetting plastic (for example, materials such as pOM) Injection molding. It includes: a central shaft 41, a bottom surface 42, a plurality of embedded slots 43 formed on the outer edge of the disc-shaped structure, and a plurality of hooks 44 formed on the disc-shaped structure's annular inner ring. The motor assembly 11 enables 4 to rotate on the support 31. The diameter of the bottom surface 42 is slightly smaller than the diameter of the center hole of the optical disc, so When the magnetic flat plate 5 drives the clamping disc 4 downward due to magnetic attraction, the bottom surface 42 can be closed to the center hole of the optical disc to rotate with the rotation of the clamping disc 4. As shown in FIG. 1 (A) and FIG. 1 (B) As shown, in the embodiment, three peripheral slots of the holding disc 4 are formed with three intervals of 120. The notch 43 is intended to be inclined between the upper surface and the bottom surface of the holding disc 4 by a specific Angle and the

Tilt. The angle ranges from 25 ° to 80 °. In this embodiment, the inclination angle of Gushanyu 1.A. port 43 is about 65. , So the clamping plate 4 is installed. At 31 o'clock of the seat 3 of the seat 3 ', the horizontal component force and the vertical component force can reach the optimum condition of f = installation. In addition, the center axis 41 of the holding plate 4 is preset to a position where the & female plate 5 is placed, and there is a hook 44 around the holding plate 44 for engaging the magnetic plate holding plate 4 thereon. Therefore, the clamping disc 4 can be actuated relative to the movement of the magnetically permeable flat plate 5 ', whereby when the magnetically permeable flat plate 5 moves due to magnetic attraction, the chucking drives the optical disc to rotate. ° Figure f shows a plan view of support base 3, of which Figure 3 (A) is its top view,

Fig. 3 (B) is a front view, Fig. 3 (C) is a back view, Fig. 3 (D) is a side view, and Wednesdays (E) and (F) are sections along lines A-A and b_b respectively. . As shown in the figure, the support base 3 is a flat plate structure with a groove and is usually formed by injection molding of thermosetting plastic (such as ABS and other materials). It includes: a base 31, a plurality of parts formed around the base 31. The recesses 32 are inserted into the slot 32 and a plurality of fixing holes 33 are formed on both sides. The holder 31 is located above the center hole of the disc in the second position of the tray 2 and has a space slightly larger than the shape of the disc of the holding disc 4 to receive the holding disc 4. When the holding disc 4 is installed therein, the holding disc 4 can rotate freely in the holder 31. In addition, a plurality of inclined ribs 32 are further formed at the peripheral position of the support surface 31 on the upper surface of the support base 3. In this embodiment, in

The peripheral position of the seat 31 is formed with three intervals of 120. The inclined rib 32 is designed to correspond to the position and shape of the central axis 41. Therefore, as shown in the sectional view of FIG. 3 (F), the inclined rib 32 is inclined between its upper surface and its bottom surface. Is 65. Thereby, the holding disk 4 is fitted into the support base 3.
