For some novice users, it can be hard to believe that in such a sophisticated device as a laptop or computer, just like in everything else, malfunctions sometimes occur. Sometimes they can be eliminated on their own at home, although in some cases you have to spend money on acquiring new components or visiting a service center. One of these problems is that the drive does not read disks.
Now in the field of
storage media there has been a clear tendency to gradually abandon compact discs in favor of flash drives. The constant availability of fast Internet has made it possible for many to forget about disks - their computers simply do not have a reader / writer. Alas, even the BluRay standard, which at one time had high hopes, appeared too late to compete with alternative solutions. It is not surprising that some computer owners do not know what to do if the drive does not read the disks.
But CDs, in comparison with the same flash drives, have one indisputable advantage - the cost. It is unlikely that anyone will be able to find a flash drive for 50 cents (this is how much a good DVD-ROM costs). And since they have not yet completely gone out of use, many are faced with the fact that the drive does not read disks.
Before considering ways to solve this problem, let's recall the theory. The basis of the CD is a metal surface with a high reflectivity. The electronic circuit of the drive generates a laser beam, which in a certain order makes recesses in this surface (process
records). While reading the recorded circuit, it captures the reflected beam and converts the order of the recesses into a stream of digital data. For example, a full return of the beam (the surface is flat) means a logical unit, and its absence (recess) means zero. Usually the problem “drive does not read disks” arises at this stage. Of course, when it comes to hardware failure. Have you ever wondered why the message “drive does not read disks” was almost never seen before?
The fact is that between the coherent light source and the disk is a focusing lens. In the early drive models, it was glass, and in modern - plastic. As you know, transparent plastic in itself is subject to turbidity, and here, too, the beam constantly passes through it. The effect is predictable - the beam focusing is deteriorating, reading failures begin, and the recording quality decreases.
What can be done? Alas, a little. Lens problems are a disaster for all modern drives that have been in use for more than two years (although there are exceptions).
It is necessary to increase the beam intensity by twisting the tuning resistors on the control board. To do this, it is recommended to contact the SC.
Another common problem is the drive does not read some drives. In this case, not everything is so simple. The device ROM contains information about the most popular types of disks (at the time the drive was sold). In accordance with these data, the device adjusts the beam strength and spindle speed. But as more and more manufacturers appear on the market, sooner or later a situation arises that there is no data on the inserted media in the device database. Hence the possible problems. The solution is simple - you need to visit the developer's website, download the firmware update for your model and flash it.
