本発明は磁気デイスクを研摩して、表面の突起
を除去するヘツドに関する。TECHNICAL FIELD The present invention relates to a head for polishing a magnetic disk to remove surface protrusions.

気デイスクの塗膜に突起が著しい場合は、浮上量
を大きくする必要がおきる。BACKGROUND ART In order to increase the recording density of magnetic disks, it is desirable to minimize the flying height of the magnetic head. If the coating film of the magnetic disk has significant protrusions, it may be necessary to increase the flying height.

0.15μｍ程度とかなり大きい欠点がある。Prior Art and Problems In order to remove protrusions on the coating surface of a magnetic disk, a polishing head with an abrasive tape attached to the base is moved back and forth in the radial direction of the disk while rotating the magnetic disk. Polish the paint surface with tape. However, since the base portion of the conventional head is a flat plate having rigidity, it is difficult to maintain a uniform interval in contact with the slightly uneven surface of the coating film. Therefore, uniform protrusion removal cannot be achieved, so the number of reciprocations of the polishing head is reduced.
10 to 15 times are required, and the remaining protrusions are high
It has a fairly large defect of about 0.15 μm.

することができる。Structure of the Invention The above-mentioned object of the present invention is to provide a head having a base supported by a leaf spring, which is used for polishing the surface of a coating film having minute irregularities, which is one of the steps of manufacturing a magnetic disk. Between the tape piece and the base on which this tape piece is attached, a film with a thickness of 2 to 3 mm and hardness
This can be achieved by a magnetic disk polishing head characterized by a 40±10 degree silicone rubber buffer.

半径方向に約1.8mm／ｓの速さで、３〜５回往復
させて得られた磁気デイスクは突起の高さが0.1μ
ｍ程度であつた。EXAMPLE An embodiment of the present invention will be described with reference to FIG. The arm 1 has a piece of abrasive tape 3 on the base portion 2 at its tip. A silicone rubber film (hardness:
40±10 degrees) with a film thickness of 2 to 3 mm. The magnetic disk 5 is rotated at about 500 rpm and reciprocated 3 to 5 times in the radial direction of the disk at a speed of about 1.8 mm/s. The height of the protrusion is 0.1 μ.
It was about m.
発明の効果
本発明の研摩ヘツドは塗膜表面をむらなく研摩
することができるので、従来の研摩ヘツドより短
時間で、同等以上の突起除去効果を得られる。Effects of the Invention Since the polishing head of the present invention can polish the surface of a coating film evenly, it can achieve the same or better protrusion removal effect in a shorter time than conventional polishing heads.
