置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a magnetic disk device, and particularly to a disk enclosure equipped with a head assembly and a disk assembly, or a plurality of disk enclosures with collars mounted concentrically inside. The present invention relates to a magnetic disk drive that is attached to a frame via anti-vibration rubber.

て複数箇所で取付けられている。Conventionally, this type of magnetic disk device has a disk assembly equipped with a head assembly and a disk assembly, as shown in FIG.
Enclosure 1 is disk enclosure 1
Attach collar 7 to frame 2 for attaching to the system side.
are attached at multiple locations with screws 5 via vibration isolating rubber 6 that is concentrically mounted inside.

ために防振ゴム６の硬度を変えて変位量を調節し、バラ
ンスをとっていた。However, since the load is not applied equally to all the vibration isolating rubbers 6 that support the disk enclosure 1, if vibration isolating rubbers of the same shape and hardness are used, the difference in displacement between the vibration isolating rubbers cannot be calculated. Ljiru. When vibration etc. are applied to the frame 2, the disk enclosure 1 behaves unstablely (referred to as rolling), and the rotating magnetic disk (
(not shown) caused a gyroscopic movement, which caused an adverse effect on the positioning of the magnetic head. Therefore, conventionally,
In order to suppress the rolling of the disk enclosure 1, the hardness of the anti-vibration rubber 6 was changed to adjust the amount of displacement and maintain balance.

方向のバネ定数も変えることになり、それまで安定した
方向に対して悪影響を与える欠点がある。The conventional magnetic disk drive described above has a circular shape as shown in Figures 2(a) and (b) using anti-vibration rubber, so by changing the hardness it can be used not only in the required direction but also in other directions. This also changes the spring constant in the direction, which has the disadvantage of adversely affecting the previously stable direction.

めかできる磁気ディスク装δを提供することである。An object of the present invention is to stabilize the state in which the disk enclosure is held against the frame of the magnetic disk drive, and to position the magnetic head while keeping the behavior of the disk enclosure stable when the frame is subjected to vibrations etc. from the outside. An object of the present invention is to provide a magnetic disk device δ.
本発明の磁気ディスク装置ｉｄ？は、防振ゴムまたはカ
ラーが楕円形の外形を有している。The magnetic disk device id of the present invention? The anti-vibration rubber or collar has an oval outer shape.
楕円の長軸、短軸の長さによって、Ｘ方向（長軸方向）

る。Depending on the length of the major and minor axes of the ellipse, the X direction (long axis direction)
, the spring constant in the Y direction (minor axis direction) can be set to 111.
次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.

It is a sectional view taken along the line A-A of FIG.
本実施例では、円形の防振ゴム３に楕円形の穴かあけら
れ、外形か楕円形のカラー４が防振ゴム３に装着されて
いる。その他は、第３図の従来例と同しである。In this embodiment, an oval hole is made in the circular vibration isolating rubber 3, and a collar 4 having an oval outer shape is attached to the vibration isolating rubber 3. The rest is the same as the conventional example shown in FIG.

同様である。The spring constants of the anti-vibration rubber 3 in the X direction and the Y direction can be adjusted by adjusting the flatness of the collar 4, and it is also possible to change the spring constant in either the X direction or the Y direction. Further, the same applies to a combination in which the outer shape of the collar is circular and the outer shape of the anti-vibration rubber is oval.
