かかる構造の磁気ディスク装置においては、磁気ディス
ク群６のうち最上部の磁気ディスクと最下部の磁気ディ
スクとの間に１．５℃以上の温度差が生じ、このために
ヘッド位置決め精度が低下するという問題があった。In a magnetic disk drive having such a structure, a temperature difference of 1.5° C. or more occurs between the uppermost magnetic disk and the lowermost magnetic disk of the magnetic disk group 6, which reduces head positioning accuracy. There was a problem.
この温度差の原因を考察するに、主に駆動機構部から出
る熱で熱せられたベース２からの輻射熱および伝導熱に
よって最下部の磁気ディスクが集中的に熱せられること
によって、叙上の如き温度差が生じると考えられる。Considering the cause of this temperature difference, it is mainly due to the fact that the lowermost magnetic disk is heated intensively by radiant heat and conductive heat from the base 2, which is heated by the heat emitted from the drive mechanism. It is thought that there will be a difference.
因みに、ベース２はアルミニウム等の金属材料で作られ
るのが普通である。Incidentally, the base 2 is usually made of a metal material such as aluminum.
したがって本発明の目的は、上下部の磁気ディスク間の
温度差を減らしヘッド位置決め精度を改善した磁気ディ
スク装置を提供するにある。Therefore, an object of the present invention is to provide a magnetic disk drive that reduces the temperature difference between upper and lower magnetic disks and improves head positioning accuracy.
しかして本発明の主たる特徴は、ベースの放熱を促進さ
せるための放熱体を設け、ベースからの熱輻射を抑制す
ることにある。However, the main feature of the present invention is that a heat radiator is provided to promote heat radiation from the base, thereby suppressing heat radiation from the base.
本発明の一実施例を第２図に説明するが、第１図と同等
部分には同符号を付して説明する。One embodiment of the present invention will be described with reference to FIG. 2, in which the same parts as in FIG. 1 are designated by the same reference numerals.
本実施例では、上ケース１とベース２との結合部分に放
熱体１２を介在させている。In this embodiment, a heat radiator 12 is interposed at the joint between the upper case 1 and the base 2.
放熱体１２は熱伝導率の良い材料、例えばベース２と同
じアルミニウムによって作られ、この放熱体１２はベー
ス２と熱的に結合されている。The heat sink 12 is made of a material with good thermal conductivity, such as aluminum, which is the same as the base 2, and is thermally coupled to the base 2.
放熱体１２は、磁気ディスク群の下側部分を取囲んで延
在しており、磁気ディスク群収容室５の内外に突出する
鍔部１３を有している。The heat sink 12 extends to surround the lower portion of the magnetic disk group, and has a flange portion 13 that protrudes into and out of the magnetic disk group housing chamber 5 .
上ケース１は、保温効果を高めるためにプラスチック等
の断熱材によって形成されている。The upper case 1 is made of a heat insulating material such as plastic to enhance the heat retention effect.
尚、上ケース１を金属材料等で形成し、その内側にプラ
スチック等の断熱面を内張すする構造も可能である。Note that a structure in which the upper case 1 is formed of a metal material or the like and a heat insulating surface made of plastic or the like is lined inside is also possible.
本実施例によれば、放熱体１２の放熱効果によってベー
ス２からの熱輻射が軽減し、また上カバー１の保温効果
によって空間１の上部側の空気の温度が上がり、その結
果として上下の磁気ディスク間の温度差を従来の半分程
度以下に減少できることが実験で確認されている。According to this embodiment, the heat radiation from the base 2 is reduced due to the heat radiation effect of the heat radiator 12, and the temperature of the air on the upper side of the space 1 is increased due to the heat retention effect of the upper cover 1, and as a result, the upper and lower magnetic fields are Experiments have confirmed that the temperature difference between disks can be reduced to less than half of the conventional value.
以上に述べたように本発明によれば、磁気ディスク群の
上下の温度差が減り、ヘッド位置決め精度の改善を達成
できる効果がある。As described above, according to the present invention, the temperature difference between the upper and lower sides of the magnetic disk group is reduced, and head positioning accuracy can be improved.
