Abstract

The present invention proposes an optical recording method and an apparatus with different recording rates utilizing loss-less data linking for effectively increasing the average recording velocity of a compact disc. The optical recording method includes the following procedures: (1) apply constant linear velocity (CLV) control pattern for the control of the recording velocity and select an initial recording velocity before continuing data recording. (2) Determine whether to increase the recording velocity is necessary based on either the spindle motor speed or the recording position. (3) Carry out the revolution speed changing procedures if to increase the recording velocity is necessary or, otherwise, continue data recording at the same recording velocity. The revolution speed changing procedures includes: (1) Suspend the data recording temporarily. (2) Write down the recording area of the disc when data recording is temporarily suspended. (3) Select a new spindle motor speed to drive the spindle motor. (4) Join the recording areas and, after the spindle motor speed becomes steady, continue data recording at the new revolution speed from the area where data recording was temporarily suspended. Thus, the present invention can work with the highest recording velocity limit of a compact disk to effectively make use of the fastest spindle motor speed for the optimization of the overall average recording velocity.

Description of the invention (4) Therefore, the invention has a different burning rate and device that can cooperate with the highest burning rate of the optical disc. The rotation speed makes the overall level be less than the f limit, and effectively uses the spindle's ten average burning rate to optimize. [Example] The following describes in detail the method and device for controlling the hair burning with reference to the drawings. Disc maps of different burning rates Fig. 3 shows that under the burn-in control mode of the present invention, the method of turning the disc to $ and the burning position method is changing the fixed linear speed system, where Fig. 3 (A) is the cut-off line of the disc rotation speed fish = imitation burning rate, and Fig. 3⑻ For the relationship between the recording rate and the recording radius, the method for controlling the recording of the disc is controlled; the: m, and: t degrees will be adjusted as the burning position changes. ^ Speed #, but the maximum speed limit of the linear speed shaft motor is not shown in Figure 3, because the slowest J degree of the main line, the burning rate; slow disk = internal; == of = turn: speed spindle two Relatively higher speed. The second = recording data, so the burning rate, the spindle motor rotation exceeds the maximum of the system = evening ", from Γ〗 The burning rate is faster as the outer circle is faster, so the average recording rate is A single-rate system. Objective 4 shows the relationship between the disc speed, the recording position, and the & recording rate in the angular velocity mode of the disc burning control method of the present invention in the linear velocity mode, where FIG. 4 (A) is The method of setting the radius of the disc and the radius of the burning position on page 8 is to burn and fix to the fixed angular rate limit of this disc. The angular velocity can be fixed at a fixed rate afterwards. The relationship between the radius and the recording of the disc recording control The degree mode is subject to the average relationship curve at the fixed line speed. For example, when the method is circled inside and outside the film, it is less than the burning line of the mode and the relative degree mode. Figure 4 (A) is used for circle data. The second is the burning control by the change point. The high rate is shown in Figure 4 (B). When this issue is issued, the maximum burning rate of the outermost disc in the fixed control mode is also increased. Yu Xi At a single recording rate, the optical disc is fixed at the angular velocity and linear velocity, so the maximum speed limit of the circle. While maintaining the one-speed and burning position burning control mode mode, the mode is changed from the high burning speed system in the previous section, so the point is changed. The southernmost recording rate is the control flow chart of t 3 0, no, cross, and fixed linear speed mode. The main condition of the figure is how to change the fixed linear speed by speed detection. Step S50 0: Start burning Step S50 2 · Drive the spindle motor in a fixed linear speed control mode, and set the initial and burning rate. The initial value of the burning rate can be determined according to the position where the burning is started, that is, based on the starting of burning. AT IP information to determine the initial value burning rate; Step S512: Increase the main speed of the spindle motor to increase the burning rate. Root Step S504: Burn the data; Step S506: Determine whether the data has been burned. If the data is burned, Then skip to step S518, otherwise skip to the next step; step S510: determine whether it is necessary to increase the burning rate, if it is necessary to increase the burning rate, skip to the next step, otherwise skip back to step S504;

498310 V. Description of the invention (6) Limit the linear speed of blood set burning according to the maximum rotation speed of the spindle motor, skip to the next step · The southernmost burning rate of the disc is determined by step S5 1 6: perform burning company step S518 · ·End. In the sequence, jump back to step S504; in step S510, it is used to determine the species. For example, it can be based on whether the motor speed is low: the rate should be increased to increase the programming rate. If you want to determine whether the recording speed is required according to the position, then the recording speed limit is used to determine the increase in linear speed: system; the maximum recording speed limit is: sound: the speed does not exceed the optical disc such as Figure 3, two of A and B: the linear speed after the Hai line is adjusted, J IU 1 stand. And when the spindle motor moves greatly, 'If the linear speed exceeds the maximum burning rate limit of the optical disc, the southernmost position of the optical disc is used. The burning rate is used as the adjusted linear velocity, for example, position C in Figure 3 (A). When the burning rate is the highest burning rate of the disc, the burning rate is no longer increased. If the burning position is used to determine whether it is required To increase the burning rate, in step S512, a burning position (ATIp information) and rotation speed correspondence table can be used to determine the adjusted motor rotation speed and burning rate. Therefore, the method of the present invention can cooperate with the highest burning speed of the optical disc. Rate limiting, and the maximum speed of the spindle motor is effectively used to optimize the overall average programming rate. Figure 6 shows the control flow of the fixed angular velocity and fixed linear velocity mode conversion.

B Page 10 498310 V. Description of the invention (7) The fixed angular velocity is measured to make the overall average burning process chart. The figure mainly explains how to change the speed detection control mode to the fixed linear speed control mode to optimize the speed. Step S60 0 0: Start burning the disc. The spindle motor is driven in a step-by-step manner, and step S6 02: Control the initial value burning rate of the mold at a fixed angular velocity; Step S 6 0 4: Burn data; Step S60 6: Determine whether the data is burned, then skip to Step S6 1 8. Otherwise, skip to the next step. If the data is burned, step S6G8: Check whether the recording rate reaches the second rate :, r, at the maximum recording rate of the disc, nr S 6 0 4, otherwise skip to the next. Step; control mode; jump back to step S604, step S6 1 2: switch to fixed linear speed control step S616: execute programming linking procedure, step S618: end. In V3602, the initial angular velocity can be the maximum speed of the spindle motor, or it can be a speed lower than the maximum speed of the spindle motor. In addition, the maximum speed and f speed can also be determined by the look-up table method (L〇〇k_up taMe) according to the burning position / the initial angular speed. Two-step attack 08 is based on the current recording rate and the maximum recording rate limit of the disc to determine the time to switch the control mode. The main decision method is to maintain the fixed angular speed control mode when the current burning rate does not exceed the maximum burning rate limit of the disc. And when the current burning rate is equal to the maximum burning rate limit of the disc, it switches to a fixed linear speed control mode, and the main fifth, invention description (8) = Yu Ran, the switching of the burning in step 86 08 The rate is not limited to the other recording speed limit of Guangbei ί = 2 recording rate limit. The maximum recording rate limitation. . Judgment is based on the programming position (ατιρ information) to perform the 技 μ technique and control system. That is, when the programming position reaches a certain preset, ρ switches to a fixed linear speed control mode without detecting the rotation speed value and the programming rate. Therefore, it is too respectful, ^ ± ten thousand. Therefore, the method of the present invention can cooperate with the southernmost recording rate limit of the optical disc, and effectively use the highest speed of the spindle motor to optimize the overall average burning rate.
