The structure is designed to prevent dust from entering, and assembly is also carried out in a clean, dust-proof room. However, if such work could be completely managed to ensure that the dust generated inside the tank does not adhere to each component, it would be possible to prevent dust from remaining inside the enclosure, or, most urgently, to prevent the dust from adhering to the disk surface. Although it would be possible to prevent dust from adhering, it would require a fairly large investment in clean equipment and operational costs, making it impractical; Although the dust that is trapped will stick to the surface of the device during assembly, any dust that tries to get into the disk enclosure from the outside will be removed by a filter, etc., so it will be difficult for new dust to get in, and the amount of dust inside will be limited. If there is a means to efficiently remove things that adhere to the surfaces of the disks, etc. that are placed inside the disk during enclosure, the water inside the assembled disk enclosure can maintain a fairly good dust-free level and contain the disk heald, etc. becomes possible.

ぐい取ることにより実現することである。(Purpose and Features) The present invention has been made with attention to these points, and its purpose is to prevent assembly during the course of assembly, that is, at the time when the disk and head are assembled into the enclosure as a head disk assembly. To remove some of the dust and dirt that has adhered to the bottom, a dust removal head with abrasive tape attached to the slider surface of the head is brought into contact with the disk surface, while the disk is rotated at low speed and slid into contact. The attached dust can be removed from the disk surface by adhering to the abrasive tape without scattering.The feature of the present invention is to remove the dust from the disk surface by adhering to the abrasive tape without scattering. In the assembly process of a magnetic disk drive formed by purchasing a drive means in a sealed manner, Uehiko Sairi et al. do not rotate the magnetic disk just before the oath that is crooked in the sealed structure without applying abrasive tape to the abutting surface. This is accomplished by inserting and sliding a dust removal head that presses and clamps the surface of the magnetic disk to wipe away the dust that has adhered to the surface.

When cams b and 7c do not support the arms, the abrasive tape portions of the respective abrasive tapes horizontally sandwich the recording surface of the magnetic head from the front and back by the arm's biasing spring force.
a, 7b, and 7c are connected to the interlocking mechanism 8 by moving the interlocking operation lever 9.
Pressure can be released by rotating the cam so as to open the space between the opposing dust removal heads via a, 8b, and 8c.

Then, set the disk in a pressurized state, and in that state, pull out the assembly 10 to near the outer periphery, repeat the return several times, and then release the operating lever 9.
When you open the head and pull it out from between the discs, dirt and flakes on the surface may adhere to the tape side.
The cleaning work is finished.

A plastic paste abrasive tape embedded with alumina with a grain size of 3 μm was pasted on a slider with a diameter of 0.01 μm and a surface roughness of 0.01 μm, and the above operation was carried out at a circumferential speed of approximately 7 m/s while applying pressure with a pressing force of approximately 350 g. It was confirmed that the dust adhering to the disk surface was wiped off.0 (Effect) As explained above, according to the present invention, the dust adhering to the surface of the disk is removed immediately before the disk is sealed in the disk enclosure during assembly. Since the assembly 10 can be incorporated, it is possible to control the amount of dust on the disk surface, or in other words, the dust inside the enclosure, to a minimum with only a short additional step.The assembly 10 was operated manually, but It goes without saying that even if it is mechanized, the effect will be the same.
