り一層の平滑さが要望されている。The flying height of the magnetic head 8 is as small as 0.2 to 0.3 μm, and with the recent increase in recording density, the flying height of the magnetic head is set smaller and smaller, making head crashes more likely. Therefore, the surface of the magnetic recording medium 3 is required to be even smoother.

気ヘッドの浮上性を劣化させ、極端な場合はへソドクラ
ソシュ等の原因となっていた。In manufacturing the magnetic recording medium 3, when a magnetic paint is applied to a substrate, orientation processing is performed to increase output. Since the iron powder in the magnetic paint is magnetized, the minute magnetic powder generated during grinding and polishing is attached to the media surface by magnetic attraction.
They become protrusions on the surface of the medium that are difficult to remove in the cleaning process. As a result, the flying ability of the magnetic head deteriorates, and in extreme cases, this causes problems such as hesodoclasosis.

ける。This cleaning vat 13 is provided with a magnetic attraction means 18 for attracting magnetic powder. The cleaning vat 13 has an elastic element made of sponge, felt, cloth, etc. at the tip of the pressing rod 14, like the conventional cleaning vat 12 shown in FIG. 7, so as not to damage the surface of the medium. , a magnetic attraction means 18 was built therein. For example, as shown in FIG. 2(A), a permanent magnet 15 may be provided at the tip of the pressing rod 14, or as shown in FIG.
As shown in b), an electromagnet consisting of a coil 16 and an iron core 17 is provided.
