本発明は、コンピューターの外部記憶装置に使用される
磁性材料ディスク板等の表面研磨に使用するラッピング
テープに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lapping tape used for surface polishing of magnetic material disk plates and the like used in external storage devices of computers.
従来、この種のラッピングテープは、ベースフィルムの
上に砥粒・樹脂を含む溶剤を塗布し、乾燥させていた。Conventionally, this type of wrapping tape has been made by coating a base film with a solvent containing abrasive grains and resin, and then drying it.
上述した従来のラッピングテープは、磁気記憶媒体のよ
うな、特にやわらかい面を研磨する場合、砥粒が、ラッ
ピングテープ表面に突出しているため、被研削面に、深
い研磨スジを残すという欠点がある。The conventional lapping tape described above has the disadvantage that when polishing a particularly soft surface such as a magnetic storage medium, the abrasive grains protrude from the surface of the lapping tape, leaving deep polishing streaks on the surface to be ground. .
本発明のラッピングテープは、テープ表面に、潤滑油か
らなる層を有している。The wrapping tape of the present invention has a layer made of lubricating oil on the tape surface.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例の断面図である。FIG. 1 is a sectional view of an embodiment of the present invention.
本実施例の製造は、砥粒１を、ベースフィルム２上に樹
脂３を介し接着し、その上に潤滑油４を塗布することに
より行う。この種のテープは、砥粒を樹脂で接着した後
、乾燥工程があるが、本実施例での潤滑油４の塗布は、
乾燥工程の前後のどちらか、又は前後ともに実施する場
合を選択できる。乾燥前に実施すると、乾燥時に潤滑油
が、砥粒層５の内部までしみ込み、強固に、潤滑層６を
形成できる。また、乾燥後では、砥粒層５の上に乗って
いるだけで、潤滑層６と砥粒層５との接着力は弱い。こ
の２者は被研磨面の状態により選択する。The production of this example is carried out by adhering the abrasive grains 1 onto a base film 2 via a resin 3, and applying lubricating oil 4 thereon. This type of tape requires a drying process after adhering the abrasive grains with resin, but in this example, the application of lubricating oil 4 was
You can choose to carry out either before or after the drying process, or both before and after the drying process. If carried out before drying, the lubricating oil will penetrate into the abrasive grain layer 5 during drying, and a strong lubricating layer 6 can be formed. Moreover, after drying, the adhesive force between the lubricating layer 6 and the abrasive layer 5 is weak because it just rests on the abrasive layer 5 . These two are selected depending on the condition of the surface to be polished.
以上説明したように本発明は、ベースフィルム上に砥粒

減できる効果がある。As explained above, the present invention has the effect of reducing round-trip flaws and scratches that occur during polishing by applying lubricating oil to a lapping tape with abrasive grains adhered to a base film.
