Description

Tool for removal and transplantation of magnetic head of Winchester hard disk and method of use thereof

technical field

The invention relates to the technical field of removal and transplantation of a Winchester hard disk head in hard disk data recovery.

Background technique

At present, Winchester hard disk occupies a dominant position in the market, with its large storage capacity, fast read and write speed, stable information recording, and the development of related supporting data management system and technical level has been quite perfect. It has the advantage that other types of storage media are difficult to replace, so it has been widely used in various places such as military, finance, government, scientific research, and business. However, when the Winchester hard drive is working, the distance between the magnetic head and the high-speed rotating platter is only about 0.2 microns, and its internal structure is very precise. When the hard disk is powered off, subjected to sudden vibration, or the voltage of the device is unstable, etc., the hard disk may be damaged. The hard disk is the warehouse for data storage. Although there are various management mechanisms and technologies for data protection, in some cases, it is still necessary to manually open the hard disk to complete the data recovery work.

When the disk platter is not scratched, the hard disk cannot work normally due to head damage, motor stuck, etc., and the data can be recovered by transplanting the magnetic head or platter. When transplanting, it is necessary to remove the magnetic head of the source disk and replace it with a new compatible magnetic head. During the whole process, the newly replaced magnetic heads should not touch each other, the newly replaced magnetic heads and the magnetic head support should not have any deformation, and the discs with data should not have any scratches. At present, in the process of transplanting the magnetic head assembly and the disk, it is usually operated manually, and the probability of successful operation completely depends on the technical proficiency of the operator. However, the structure of the hard disk is too precise, even if the operator is skilled and careful, the success rate of replacing the magnetic head assembly is relatively low. Currently, operators usually use cut or trimmed rubber blocks, origami blocks and other objects, and use tweezers to separate the magnetic heads. For each type of magnetic head assembly, a lot of practice is required to ensure a certain success rate; and objects such as rubber blocks or paper blocks used for separation will contain a large amount of dust that is invisible to the naked eye. There will be pollution in the warehouse, which will reduce the success rate of data recovery; in addition, there is no suitable temporary storage device and equipment for the transplantation process of the magnetic head assembly. The probability of recovery success is reduced.
