Abstract

A kind of method for preventing optical pick up of CD-ROM drive from too high temperature when performing read/write operation is disclosed in the present invention. A temperature detector is disposed in the optical pick up, and a temperature adjustment module is built inside the CD-ROM drive. The method includes the following steps. At first, the temperature detector is operated to detect the operation temperature of the optical pick up. Then, the temperature adjustment module is used to judge whether the operation temperature is higher than the predetermined maximum starting temperature. When the operation temperature is higher than the maximum starting temperature, temperature adjustment module will slow down the read/write speed of the CD-ROM drive to decrease the generation of heat source so as to decrease temperature of the CD-ROM drive. Thus, it is capable of effectively protecting optical pick up and preventing it from being damaged under too high temperature environment.

Description of the invention (6) In a preferred embodiment, the above-mentioned temperature control module 28 includes a temperature detection function and a double speed adjustment function. Among them, the temperature detection function can be combined with the original monitoring program (m ο n i t 〇 r c 〇 d e) in the s memory. A typical monitoring program can continuously monitor the optical read / write head 24, the servo motor 22, and the drive circuit 20 at intervals of about several tens of microseconds according to the initial setting, and send the relevant information back to the central processor 1 2 . Therefore, the temperature detection function 3b is integrated into the original monitoring program, so that each time the monitoring program performs a monitoring operation, the required temperature is obtained through the temperature detector 26 in the optical read-write head 24 at the same time. Temperature data. When the detected temperature exceeds the above-mentioned maximum starting temperature, the central processing unit 12 will control the servo system 18 to reduce the speed of item retrieval / burning according to the double speed adjustment function. The central processing action is detected for reading and writing performance regulation. For example, when the temperature is the same as the above-mentioned visual control module 28 for the temperature of the optical disc drive, the optical disc drive can maintain the highest speed in the temperature allowable range. In addition to the mechanism for reducing the reading / writing speed described above, in the temperature group 2 8 A temperature range is set according to the maximum startup temperature. When the temperature is less than the maximum starting temperature minus the value in this temperature range, the value 12 will control the servo system 18 to increase the read / write speed. Generally, this temperature range can be set between 5 and 10. & When the normal range is set to 5 ° C and the maximum startup temperature is 65 ° C, when the temperature detected by j exceeds 65, the temperature control module 28 will reduce the speed of 5 purchases in order to reduce the power output and Reduction; on the other hand, when the detected temperature is lower than 60 ° C, the temperature adjustment will increase the reading speed of the optical disc drive, so that it can maintain a relatively high level of the invention. (7) Work efficiency 28 adjustment : Disc player continued to take: This picture does not show the temperature of the temperature control module 28? … As mentioned above, due to temperature regulation, the first step is to execute the adhesion monitoring program. Because ^ 仃 S ^ is 20 microseconds of the read monitoring program C step g (n -fr means that the disc drive is monitored once every 2Q microseconds: Measurement: whether the price measurement delay of the degree function is 0 times In the case of: check = :: the number of times. When the time is set, the detection delay will be reduced in step 33 after the completion of the operation of the parent and the secondary monitoring program, and the number of intervals from i to the detection delay will change. When it is 0, the temperature will be detected during the monitoring operation. After measuring the working temperature of the optical head, the person compares whether it is higher than the maximum starting temperature (step 34). If it does not exceed the maximum start-up temperature, check whether the speed is the same as the read speed originally set for this drive (step 36). When Muli's reading speed is lower than the original speed set by the optical disc drive, 'determine whether the detected temperature is lower than the maximum startup temperature (Tmax) minus the temperature range (T1)' (step 38) 'that is to check Check whether the temperature is lower than (Tmax-T1). On the right, the double-speed control function of the temperature control module 28 'will increase the reading speed of the optical disc drive (step 40). In a preferred embodiment, when the optical head used has an operating temperature of 0 ~ 6 5 t, the maximum starting temperature Tmax can be set to 65 ° C 'and the temperature range can be set to 5 ~ 101. · 1 IBH1 588334 V. Instructions (8) ° C.

一般來說，由於光碟機溫度的變化，並不會在調整光學頭的讀取速度後立刻顯現，因此為了避免讀取速度調升得過快或過多，在每次調升讀取速度後，會延遲一段時間’再進行溫度的債測，以便能更精確的掌握在不同的讀取速度下，光學頭的溫度變化情形。因此，在調升光碟機的讀取速度後，會將偵測溫度功能的偵測延遲設定為2 〇〇次間隔（步驟4 2 )，以便在監測程式後續的第2 〇〇次監測動作時，再進行下一次溫度的偵測。隨後，繼續執行監測程式（步驟4 4 )。以上述監測程式的間隔設定為2 〇微秒而言，在經過（2 0被秒）* ( 2 0 0次間隔）的時間後，便會再度進行溫度的偵測。亦即，在大約4秒鐘的時間後，便會進行下— 次的溫度偵測。Generally speaking, because the temperature change of the optical disc drive does not appear immediately after adjusting the reading speed of the optical head, in order to avoid the reading speed being raised too fast or too much, after each reading speed increase, It will be delayed for a period of time before the debt measurement of the temperature, so that the temperature change of the optical head can be more accurately grasped at different reading speeds. Therefore, after the reading speed of the optical disc drive is increased, the detection delay of the temperature detection function is set to an interval of 2000 times (step 42) so that when the monitoring program follows the 2000th monitoring operation, , And then perform the next temperature detection. Subsequently, the monitoring process is continued (step 4 4). Taking the interval of the above monitoring program as 20 microseconds, the temperature will be detected again after the time of (20 seconds) * (200 times interval) has elapsed. That is, after about 4 seconds, the next temperature detection will be performed.

至於，在上述步驟3 4的判定中，如果光學頭的工作溫度已超過最大啟動溫度，則判斷目前的讀取速度是否仍大於光碟機的最小讀取速度（步驟4 6 )。若是，則顯然光碟機仍有降低倍速的空間，因此可在螢幕上顯示訊息以告知使用者，且經由中央處理器1 2傳送訊號至電腦系統中正在使用光碟機的相關應用軟體（步驟48 )。然後，可將讀取倍速降低兩倍（2 X )(步驟5 〇 )，並且將偵測溫度功能的偵測延遲設定為2 0 0次間隔（步驟5 2 )，以決定下次進行溫度偵測的時間。As for the determination in step 34 above, if the operating temperature of the optical head has exceeded the maximum startup temperature, it is determined whether the current reading speed is still higher than the minimum reading speed of the optical disc drive (step 46). If so, it is clear that the optical disc drive still has room to reduce the speed, so a message can be displayed on the screen to inform the user, and a signal is transmitted to the relevant application software of the optical disc drive in the computer system via the central processing unit 12 (step 48) . Then, the reading speed can be reduced by two times (2 X) (step 5 〇), and the detection delay of the temperature detection function is set to an interval of 200 times (step 5 2) to determine the next temperature detection. Measured time.

This can be set to 'When one of the above steps 4 to 6 is the same, Tidi I 疋 drive has not reduced the speed to display a message to inform the user, and stop the optical head-take two: the relevant application software (step 54). Then (Λ 8 step 56), and turn off the servo system ΓΛ: to reduce the temperature of the optical head. Until the subsequent value (step ⑷, which is lower than the value of (Tmax_T2), and then set the relevant settings (step 6 2), and then enter the lean material reading and transmission procedure (step 64). As before, the maximum starting temperature Tmax is set to 65 °, and the temperature range τ2 is set between 1 ~ 5 ° C to resume the reading operation of the optical disc drive as soon as possible. 41 Next, please refer to the third figure, this The figure shows the application of the temperature control module 28 of the present invention to adjust the writing speed of the burner. Similar to the read case, a burn monitoring program with an interval of 20 microseconds is first executed (step 70), that is, every time 20 microseconds, a condition monitoring is performed. Next, check / check whether the measurement delay is 0 intervals (step 72). When the monk measurement delay is 0 intervals, immediately perform temperature detection simultaneously in the current monitoring program.
