本発明は、磁気ディスク装置のキャリッジ部に関し、特
に、モータの駆動力をラックピニオンでキャリッジに伝
達する方式における、ラック形状に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a carriage portion of a magnetic disk device, and particularly to a rack shape in a system in which driving force of a motor is transmitted to the carriage by a rack and pinion.
従来の磁気ディスク装置のキャリッジ部ラック形状は、
Ｕ、Ｓ、Ｐ、４．４２ａ０１２に記され、第３図に示す
ように、ラック３４には溝が切られていなかった。The shape of the carriage rack of a conventional magnetic disk device is
As noted in U, S, P, 4.42a012 and shown in FIG. 3, the rack 34 was not grooved.

There was a phenomenon in which abrasion powder due to wear of the teeth of No. 7 accumulated on the rack 34, and residual υ of grease applied to the rack 34 to reduce wear accumulated on the rack 34 as well as abrasion powder. Abrasion powder and grease accumulated on the rack 54 are
It was blown away by the airflow inside the magnetic disk drive, polluting the air inside the magnetic disk. A major problem was that the magnetic head became cluttered due to abrasion particles and grease scattered in the air.

る。Therefore, in order to solve such problems, the present invention provides a magnetic disk drive having a carriage mechanism using a rack and pinion, in which abrasion powder and grease from the rack and vinyl door are not scattered inside the magnetic disk drive. The objective is to be able to install magnetic disks with fewer head crashes.

中央部に溝を切ったことを特徴とする。In order to solve the above problems, the magnetic disk drive of the present invention is characterized in that grooves are cut in the perpendicular direction to the teeth of the rack and approximately at the center of the rack.
以下に本発明の実施例を図面にもとづいて説明する。第

第２図に示すように、溝が切っである。Embodiments of the present invention will be described below based on the drawings. In FIG. 1, a rack 14 is fixed to a carriage 13 on which a magnetic head 12 is mounted to be moved and positioned above a magnetic disk 11. As shown in FIG. The rack 14 is in contact with a pinion 17 cut into the shaft 16 of the carriage drive motor 15 under preload. Here, in the rack 14,
As shown in FIG. 2, the grooves are cut.

生する摩耗粉をラック溝部に導き、同時に余剰グリース
もラック溝部に導く。According to the magnetic disk drive configured as described above, wear particles generated on one side of the rack, especially because the binion and rack have an inclination that cannot be corrected even by adjustment during assembly, are guided into the rack groove. At the same time, excess grease is also guided into the rack groove.

ニオン部には、常にクリーンなグリースが供給されるよ
うになる。また、グリースは溝部に余剰分がたまるため
、ヘッドシーク時にグリースが飛散することもなくなる
のである。Due to the difference in specific gravity between the wear powder and grease accumulated in the groove, the grease accumulates on top of the wear powder, and clean grease is always supplied to the rack binion. Furthermore, since excess grease accumulates in the groove, the grease will not scatter during head seeking.
