Offer some help for meeting the puzzled friend while choosing the optical drive.
The first, Read a ability . Reading a ability is to correct ability by mistake. As VCD machine, to correct by mistake ability the very important optical drive. CD have outside protect shell, it rows wounded so ability who optical drive’ read sodden ones’ seem essential. Can take a’ sodden disc’ while choosing, test in person. Whether the optical drive that should pay attention to selecting at the same time has been adopted some and corrected technology by mistake . Have it is neither public praise to pay attention to products nor well-known brand correct by mistake ability should have been good by optical drive, A ability a little more outstanding that the optical drives of some of brands are read.
Second, The speed. At one the forms of speed mark the speeds of optical drive, the speeds of optical drive 150 kB/ses single speeds, The speed of optical drive of speed 4 is 600 kB/ses, analogize with this. But from behind speed of 16 times optical drive, the speed of the optical drive no longer accords with and marks the calling value strictly, Often just reaches and marks the calling value when being a outer lane which reads the CD, this is the reason why mark’ MAX’ printed words on a lot of optical drives panels too. Generally speaking, are used in general family amusement, ordinary user who plays the CD game, It considers and buy the optical drives of speeds have relatively high friend that requires consider and buy 48 or the optical drives of speeds to speed.
The optical drive of high speed will often bring shaking, noise, and while reading the CD, Laser want and comply with dishes of Taxi vibrations make repeated focus movement, influence ability by mistake of correcting by head, This is exactly a lot of optical drives at present too there is reason which lower the speed function. The manufacturer of some optical drives has paid attention to the improvement in this respect. Have adopted ABS homeostasis systematic technology in its product. ABS technology is to put balls in the main shaft of the optical drive, improve the performance when the optical drive reads the disc with uneven density. When the optical drive reads the partial disc, the ball function because of the centrifugal force under the tray, It is balanced in twinkling of an eye to know and go to a light side of quality to realize. However, avoid and shake technology have pairs of oil pressure trends avoid and shake system, rubber shock attenuation technology, etc. adopt at present. While choosing, the optical drive that you can noticed and selected has been adopted and avoid shaking technology .
The third, Mechanical question. At the promotions of speed, the caloric values of optical drive increase much, because heat-resisting ability relatively poor traditional plastic inner works really, Use and happen out of shape for a long time and read one wait for phenomenon smoothly. Optical drive dispel the heat unable to solve through fin, however, high to generate heat the question causes people’s attention. In order to solve these problems, some producers have already used the inner works of all steel to make optical drive. Though the cost relatively ordinary optical drive of optical drive which uses the steel movement should be high, the life-span improves notably, From the view point of longing run, it is very worth that it costs one more twenty yuan to buy a all steel movement.
The fourth, After-sale service. The after-sale service is only the question of guaranteeing a accident of the quality, last three months by one according to different brands in optical drive products guarantee period of now, The size of guarantee period has embodied the confidence to one’s own products of producer in the certain degree.
In a word, present even more doing without the optical drive of computer, it helps to be chosen and use correctly to fully realize the optical drive. Hope that the orientation meeting above helps you to some extent.
