Description of the invention (1) Field of the invention The data and description of optical discs The present invention provides a method for accessing one using an optical disc drive, especially a method of using the optical disc drive to retrieve directory data to the optical disc method. BACKGROUND OF THE INVENTION The rapid development of computer technology for digital slaves, most of the data is of a single-bit type to facilitate transmission and storage. In order for F to be converted into digits of data, various types of data storage are also successively set:] 更 Γΐϊ One example is a mechanical disc. The optical disc drive makes full use of the characteristics of light 2 and small 2 and large capacity, and records digital data on the light, so that users can save data more conveniently. Ding Yu, please refer to the data sheet for information. The photoresist is expanded and covered with a photoresist, including a light 20, the light (on and the resist layer 24 is broken through the laser ^ Figure 1, Figure 1 shows the conventional optical disc drive. The optical disc 20 includes a spiral point track 22 with a disc 20, a track layer 24 (not shown), and a disc head I2. When the optical disc drive 10 writes the data to the optical disc Γ u, according to the data (0 or 1), the light in the track 22 of the optical disc 20 is sent or not. The photoresist layer 24 in the 2 ° track 22 exposed by light will leave 594703 in the track 22. V. Description of the invention (2) (P 11) 'and the photoresist layer in the track 2 2 2 4 The area that has not been illuminated by laser light will remain flat (1 and). Since the reflectivity of laser light emitted by optical pickup 1 2 in pits and flat places is not the same, the Potholes and flats can represent different data content (for example, the digital "0" and "1"). On the other hand, when the optical disc drive is read When the data stored in the optical disc 20 is used, the optical disc drive 丨〇 can receive the laser light reflected by the optical disc 2 with the optical pickup 丨 2 and interpret the stored optical disc according to the situation of the laser light reflection. According to the provisions of the Orange Book, the track 22 of the optical disc 20 can be formatted into at least one section (sessi) from the inside to the outside, and each section contains a kind of area (area ) · Lead-in area, P-gram data area, and lead-out area. Please refer to the second H diagram. The optical disc 20 includes at least a section 26, a section 26, a lead-in area 28, a program data area 30, and a lead-out area 32. The program can use ^ to store one or more tracks, each of which is ancient, and the data or audio data of the second district. Generally, i is combined; and the data type stored in the solid = 3 is data data, then the segment 26 fid, that is, the optical disc 20 may include a plurality of segments; £ ei # ί 二二 / The data stored in it are all For audio data, the segment and the optical disc 20 may still contain a plurality of magnetic numbers in the segment material area 30:! 2 contains data for the program data area 3 of the segment 26. Internal resources; = starting position, and J Bei 枓 length # lean material in section 26. The above three kinds of data are collectively called

In the lead-out area 32 of the segment 26, the digital mute uigitai siience) and other data are read. When the optical disc drive ^ first learns the read head 12 and reads the silent data in the lead-out area 32, it can be judged that the optical pickup 丨 2 has the area Section 26, all data reading is completed. In the 30 yuan, the lead-in area of the section “2〇之 ί” contains 4,500 storage sectors (sectors), and the length of the mother-storage unit is each of the children ’s early films of 20 The length of the lead-in area of a sector is 2K Λ group_ so 1::.
