型磁気ディスク装置に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an access control system having a drive shaft loaded with a magnetic recording medium for recording information, and a magnetic head for recording and reproducing information on the magnetic recording medium. The present invention relates to a so-called shielded magnetic disk device including a head disk assembly in which a drive portion is sealed and housed by a base housing and a cover to which the drive portion is fixed.

トを介してねじ固定されている。In conventional shielded magnetic disk drives, magnetic recording media (magnetic media) for recording information are stacked parallel to a drive shaft via precision-machined spacers. The bearing portion of the drive shaft is supported by a base housing whose centrality is highly accurate, and is screwed from the end face of the base housing via a fixing plate.

対応している。The conventional shielded magnetic disk device as described above is
In order to maintain a relatively constant height between the magnetic medium and the magnetic head that records and reproduces information on it, the machining accuracy of the individual parts of the magnetic medium and spacer loaded on the drive shaft is increased. In addition, by interposing an adjustment spacer between the end face of the base housing and the fixing plate, the height of the entire drive shaft can be changed.

る。In such a structure, if the accuracy of the concentricity of the bearing holding part of the base housing or the accuracy of the parallelism of the outer surface of the bearing part of the drive shaft that comes into contact with the fixing plate is poor, the drive shaft may be installed at an angle. The disadvantage is that it is impossible to make adjustments. Another disadvantage is that spacers of various thicknesses must be prepared in order to adjust the height of the entire drive shaft.

is raised high. Therefore, by tightening the adjusting screw 20 and adjusting the height, the drive shaft 1 can be pulled up vertically or its inclination angle can be changed. Adjustment screw 2
A steel ball 21 is provided at the tip of 0, and the adjustment screw 20 and the steel ball 21 are in contact at one point. Therefore, adjusting screw 2
It generates less dust when turning 0, and the resistance is small, so it can be turned easily. Furthermore, by providing a gasket 22 between the fixed plate 8 and the base housing (bearing part) 6, dust generated due to the contact between the adjustment screw 20 and the steel ball 21 can be prevented from entering the magnetic medium 2. It is possible to prevent and prevent

Due to a bad condition, the II drive shaft was installed at an angle.
When the angle of inclination can be changed by adjusting the height, tightening the adjustment screw has the effect of changing the angle of inclination. Another advantage is that there is no need to prepare spacers of various thicknesses to adjust the height of the entire drive shaft.
