タの読み書きができなくなる。 In conventional sealed magnetic disk devices, especially those with a high density of data in the radial direction of the magnetic disk, track following is performed by the servo surface of the magnetic disk and the servo head.
That is, the servo head automatically tracks the commanded track position), and the data head is positioned on the target data track of the magnetic disk.
At this time, servo disk (magnetic disk with servo surface)
If a temperature difference occurs between the data head and the data disk (the magnetic disk having the target data track), the data head will be displaced from the target data track, making it impossible to read or write data.

円板を持つ磁気デイスク装置では、送風機でエア
フイルタを通して強制的に各磁気円板間にほぼ同
等に風を吹き付け各磁気円板間の温度差を生じな
いようにしている。 Generally, in a magnetic disk device that has multiple magnetic disks that introduce outside air as a pair, a blower is used to forcibly blow air almost equally between each magnetic disk through an air filter, creating a temperature difference between each magnetic disk. I try not to.
しかるに密閉形磁気デイスク装置では、空気は
内部循環であるため、空気の流れが装置内で偏り
がでやすく、サーボ円板とデータ円板の温度差が
生じ易い欠点があつた。 However, in a sealed magnetic disk device, since air is circulated internally, the air flow tends to be uneven within the device, and a temperature difference between the servo disk and the data disk tends to occur.
この発明は密閉形であつても各磁気円板に同等
の風を吹きつけ各磁気円板間に温度差の生じない

とするものである。 The object of the present invention is to provide a closed type magnetic disk device that blows the same amount of air onto each magnetic disk and does not cause a temperature difference between the magnetic disks even if it is a closed type.

穴12があけられている。 In the sealed magnetic disk device constructed as described above, the spindle 1 is rotated counterclockwise when viewed from above in FIG. 1 by a motor comprising a stator 6 and a rotor 5. This rotation causes the hub 7 to
The grooves 11 cut in a spiral shape on the side surface create a flow of air from top to bottom. In this case, the air intake port is a hole made in the disc retainer 10, but it is omitted in FIG. Air flows from groove 11 to spacer 9
Air flows 13 through the upper hole 12 and flows out while uniformly cooling the magnetic disks 8 as shown by the arrows, so that each magnetic disk 8 is equally cooled. In addition,
A large number of holes 12 are drilled in each spacer 9 such that at least one hole 12 in each spacer 9 directly faces the groove 11 .
