Description
Technical field
The present invention relates to the technical field of CD-ROM drive aspect, especially relate to by adjusting CD-ROM drive operating rate unnecessary noise and reduce the technological improvement of the probability of quick-fried of discs when reducing the CD-ROM drive running.
Background technology
Along with user's demand, at present the reading speed of CD-ROM drive is promoted to now 52 times of speed from 8 times of early stage speed.Yet, increase along with reading speed, to the motor rotary speed of ray machine be improved day by day, incident problem also just the more, for example, (discs has distortion or scratch, when perhaps discs structural strength deficiency, thickness deficiency or heat resistance are relatively poor for noise and quick-fried problem, bigger noise all takes place under running up easily, even quick-fried).More specifically, only when reading great mass of data, just may be greater than the reading speed of 24 times of speed, under most situations, for example under the situation of play CD or VCD, CD-ROM drive only need turn round and can satisfy the demands under 24 times of speed of reading speed.Therefore, the reading speed of adjusting CD-ROM drive according to circumstances is in order to reduce noise and to reduce the practice commonly used of quick-fried situation.
The way of adjusting the CD-ROM drive reading speed at present mostly is to make the reading speed of CD-ROM drive change its value by the running software mode by the user, and its shortcoming is comparatively to bother in the operation.Another kind is mode eaily, be to quicken by the button on the CD-ROM drive, the ESC Escape that for example ought push on the CD-ROM drive surpasses the schedule time, even this CD-ROM drive is promoted to high reading speed, its shortcoming is after finishing acceleration, unless move back sheet, otherwise can't be cut to original reading speed, simultaneously, it can not change this high reading speed by the running software mode voluntarily by the user.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of CD-ROM drive of adjusting the method for CD-ROM drive operating rate and implementing this method, in order to noise effect and the quick-fried generation probability that reduces CD-ROM drive.
For achieving the above object, this method is determined the high operation speed of this CD-ROM drive earlier by user oneself, and this step can be finished by a setup unit that operates in a computing machine.Then, make this CD-ROM drive can be according to a generation that activates incident, select this high operation speed and in advance in be built in one of them real work speed of the standard operation speed of this CD-ROM drive as this CD-ROM drive.Wherein, this real work speed determines according to following step:
Obtain the present operating rate of this CD-ROM drive; And
Judge whether this present operating rate is higher than this standard operation speed, and when judged result is " very ", making this CD-ROM drive is its actual operating rate with this standard operation speed, when judged result is " vacation ", makes this CD-ROM drive be its actual operating rate with this high operation speed.
Because it is in down running of standard operation speed (for example 24 times of speed of reading speed) usually that this method can make this CD-ROM drive, and only when being arranged, demand just is operated to high operation speed (for example 52 times of speed of reading speed) by the user.Therefore, this CD-ROM drive of most time is to be in the low noise situation, and therefore, the noise effect of this CD-ROM drive can minimize.
In addition, the high operation speed of this CD-ROM drive determines by following step:
Determine high operation speed expectation value by the user;
Obtain the specified high operation speed of this CD-ROM drive; And
Judge whether this high operation speed expectation value is higher than this specified high operation speed, when judged result is " very ", make this high operation speed equal this specified high operation speed, when judged result is " vacation ", make this high operation speed equal this high operation speed expectation value.
The high operation speed of this CD-ROM drive is to be decided in its sole discretion by the user.Though for example the specified high operation speed of CD-ROM drive is 52 times of speed (referring to reading speed), but the user can consider according to employed discs quality and low noise, this high operation speed is set at 32 times of speed (referring to reading speed), therefore, this CD-ROM drive can only turn round under 32 times of speed of reading speed at most, and the situation of its quick-fried of generation and high noisy can reduce naturally.

Embodiment
With reference to figure 1, show a preferred embodiment of the present invention, wherein disclose a computing machine 1, CD-ROM drive 2 that connects with its electricity of installing on this computing machine 1, these CD-ROM drive 2 outsides have a speed change button 20, an execution/search button 21, reach one stops/moving back sheet key 22.
In addition, these CD-ROM drive 2 inside have a control module (not shown) of its running of control, and this control module is decided at the higher level but not officially announced one high operation speed and a standard operation speed via the solid design mode, and this high operation speed is more than or equal to this standard operation speed.In this example, the value of this high operation speed can be changed by a setup unit that may operate at this computing machine 1 by the user.The value of this standard operation speed then is by promptly not changed by the user after manufacturer's decision.
With reference to figure 2, when pressing this speed change button 20, an activation incident takes place promptly.At this moment, the control module of this CD-ROM drive 2 is obtained the present operating rate of this CD-ROM drive 2 earlier according to this generation that activates incident, and judges and then whether this present operating rate is higher than this standard operation speed.When judged result was " very ", making this CD-ROM drive 2 was its actual operating rate with this standard operation speed, when judged result is " vacation ", made this CD-ROM drive 2 be its actual operating rate with this high operation speed.
Wherein, need subsidiary this high operation speed that be pointed out that to refer to the high reading speed or the highest motor rotary speed of CD-ROM drive, this standard operation speed refers to the standard reading speed or the standard motor rotary speed of CD-ROM drive, this real work speed refers to the actual reading speed or the actual motor rotating speed of CD-ROM drive, and this present operating rate refers to the present reading speed or the present motor rotary speed of CD-ROM drive.Therefore, the reading speed of CD-ROM drive and motor rotary speed are the saying of one integrity with both sides in fact, and reading speed is represented the motor rotary speed height soon, and vice versa.But, when the operating rate of CD-ROM drive is discussed, use reading speed person traditionally, based on such reason, example is subsequently used the operating rate that reading speed is expressed CD-ROM drive instead.
Suppose that this CD-ROM drive 2 is by the experience of user according to oneself, changing its high reading speed is 32 times of speed, and this standard reading speed is decided to be 24 times of speed in, and CD-ROM drive 2 turns round under 24 times of speed of this standard reading speed at present, and promptly the present reading speed of CD-ROM drive 2 is 24 times of speed.When pressing this speed change button 20, because reading speed (24 times of speed) is not greater than this standard reading speed (24 times of speed) at present, this expression user wishes to improve the reading speed of CD-ROM drive at this moment, therefore, the actual reading speed of this CD-ROM drive 2 is set to this high reading speed (32 times of speed), in other words, this CD-ROM drive 2 has quickened.Then, click this speed change button 20 again, at this moment, because the present reading speed of CD-ROM drive 2 is because of previous variable speed operation is promoted to 32 times of speed, so, reading speed (32 times of speed) is greater than this standard reading speed (24 times of speed) at present, this expression user wishes to reduce the CD-ROM drive reading speed at this moment, and therefore, the actual reading speed of this CD-ROM drive 2 is set to this standard reading speed (24 times of speed), in other words, this CD-ROM drive 2 has slowed down.
From above-mentioned explanation, can recognize, the inventive method can make this CD-ROM drive 2 switch at high operation speed and both intercropping of standard operation speed, and, this CD-ROM drive 2 of most time is in the low noise state under this standard operation speed owing to turning round, in other words, the noise effect of this CD-ROM drive 2 can minimize.
In addition, what need particularly point out is, above-mentioned high operation speed is not the specified high operation speed of CD-ROM drive 2, and this high operation speed is to be decided according to step shown in Figure 3 by a setup unit that runs on this computing machine 1.The specific practice of this setup unit (not shown) is design one application program execution graph 3 described steps, that is:
At first, import high operation speed expectation value (X) earlier by the user;
Then, obtain the specified high operation speed of this CD-ROM drive 2, and judge whether this high operation speed expectation value (X) is higher than this specified high operation speed, when judged result is " very ", make this high operation speed equal this specified high operation speed, when judged result is " vacation ", make this high operation speed equal this high operation speed expectation value (X).
In this example shown in Figure 3, this high operation speed refers to the high reading speed or the highest motor rotary speed of CD-ROM drive, and this specified high operation speed refers to the specified high reading speed or the highest specified motor rotary speed of CD-ROM drive.Similarly, use reading speed in the majority traditionally owing to express the operating rate of CD-ROM drive, so example is subsequently used the operating rate that reading speed is expressed CD-ROM drive instead.
The specified high reading speed of supposing this CD-ROM drive 2 is up to 52 times of speed, but considers low noise and optimum efficiency, and still suggestion preferably is set in this high reading speed the scope of 8～32 times of speed, is the best with 24 times of speed wherein.Because the high reading speed of this CD-ROM drive 2 is only to 32 times of speed, therefore, its situation that quick-fried and high noisy take place certainly reduces.This is to allow the user decide one of benefit of this high reading speed in its sole discretion.
In addition, be not provided with at CD-ROM drive under the situation of this speed change button 20, can trigger above-mentioned activation incident yet by the mode of pushing this execution/search button 21 simultaneously and stopping/moving back sheet key 22.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
